Best Spark Plugs For Rzr 1000: NGK MR7F and Iridium Options

#1 · Best Overall

1. Quad Logic MR7F Pair

• Compatible with Vehicle Type: ATV, UTV, Side-by-Side
• Core Material: Copper
• Top Material Type: Nickel alloy

Best for: OEM-style twin-cylinder pair.

Why it ranks #1: The two-plug set uses NGK MR7F plugs and replaces Polaris numbers 3022662, 3022639, 3022462, and 3022274 for listed twin-cylinder models.

A two-plug set of NGK MR7F plugs is Quad Logic’s clearest advantage, enabling a paired replacement for compatible twin-cylinder Polaris machines. The listing calls these direct OEM replacements and names RZR, Ranger, Sportsman, ACE, General, and RS1 models, with several Polaris factory part numbers covered.

The pair is specified for twin-cylinder Polaris models, so buyers needing both plugs can source them together rather than purchase a single replacement. Direct replacement references include 3022662, 3022639, 3022462, and 3022274, and the description says the plugs match OEM specifications and install like the originals. NGK MR7F plugs are also presented as supporting reliable ignition, steady power delivery, and smooth idling; check the exact vehicle application before ordering.

Skip it if you need only one replacement plug; Quad Logic’s NGK MR7F package is sold as a pair.

This suits owners replacing both plugs on a listed twin-cylinder Polaris RZR or related model who want an NGK MR7F direct replacement. Match the vehicle and factory part number before buying.

#2 · Best Iridium Pair

2. AIP Dragon Fire Iridium

Best for: Iridium RZR replacement pair.

Why it ranks #2: This two-piece iridium set lists RZR 1000 compatibility for model years 2011–2020 and replaces NGK 95897 and several Polaris numbers.

Iridium electrode technology is the defining feature of AIP Electronics’ Dragon Fire pair, and the listing says it enables quicker cold starts and faster acceleration. The plugs are presented as OE-fit replacements for a broad range of 2011–2020 Polaris machines, including RZR 1000 models, with NGK 95897 and MR7F replacement references.

The two-plug set suits buyers replacing both plugs together, while the stated OE factory fit and testing to match OE fit support a familiar replacement workflow. Iridium electrodes are linked in the listing to quicker cold starts and faster acceleration, useful when responsive starting and pickup matter. Compatibility spans listed Polaris ACE, General, Ranger, and RZR models, including 1000, but the seller specifically advises checking its fitment chart; verify the exact year and model before ordering.

Skip it if you need a single plug or a model outside the listed 2011–2020 Polaris range; this set contains two plugs.

Choose this pair if your listed Polaris RZR 1000 application calls for the referenced replacement plug and you want iridium electrodes. Check the chart against your exact year and model before purchase.

#3 · Best Single Plug

3. Quad Logic MR7F Single

• Compatible with Vehicle Type: UTV
• Core Material: Copper
• Top Material Type: Copper

Best for: Single NGK MR7F replacement.

Why it ranks #3: A single NGK MR7F replacement is listed for RZR 1000 models from 2014–2020 and replaces Polaris part numbers 3022274, 3022462, 3022639, and 3022662.

Sold individually, this genuine NGK MR7F replacement lets a Polaris owner replace one failed plug without buying a pair. Quad Logic lists RZR 570, 900, and 1000 applications alongside Polaris replacement numbers, making the single-plug format the key distinction for targeted maintenance.

The listing identifies the plug as an exact replacement for specified Polaris models and names part numbers 3022274, 3022462, 3022639, and 3022662. Its description includes RZR 570, RZR 900, and RZR 1000 fitment across stated model years, while the individual sale format is useful when only one plug is being changed. Confirm the full product description’s fitment details for the exact RZR year and version before installation.

Skip it if you want both plugs in one purchase; Quad Logic’s paired NGK MR7F set is sold as a two-pack.

Consider this for a one-plug repair on a listed RZR 570, 900, or 1000 when the MR7F and replacement number match. Its individual format is not a complete pair.

#4

4. SUKATC MR7F Plug

• Compatible with Vehicle Type: ATV, UTV

Best for: Listed RZR and Ranger fitments.

Why it ranks #4: This single-plug listing names MR7F and Polaris replacement numbers, with verified fitment details covering multiple RZR and Ranger 570 and 900 models.

SUKATC lists specific RZR and Ranger applications, including RZR 570 and Ranger XP 900 versions, giving buyers a named fitment range to check before replacing a plug. The package contains one MR7F-compatible spark plug and identifies several Polaris replacement numbers.

The one-plug package is associated with 3022274, 3022462, 3022559, and 3022639, while the verified applications include RZR 570 variants and multiple Ranger XP 900 trims. That model detail can help narrow the fitment check beyond a broad vehicle label. Because the supplied application list does not establish every RZR 1000 year or version, match the exact machine and replacement number before installation; this is a single-plug purchase, not a pair.

Skip it if you need confirmed RZR 1000 fitment; the listed verified applications identify RZR 570 and Ranger XP 900 models instead.

This is a candidate for owners whose RZR 570 or Ranger XP 900 trim and replacement number appear in the supplied fitment details. Do not treat its broad title as confirmation for every RZR 1000.

#5 · Best Wire Kit

5. MOTO1988 Plug Wire Kit

• Compatible with Vehicle Type: UTV
• Core Material: Iridium
• Top Material Type: Iridium

Best for: Plug-and-wire service kit.

Why it ranks #5: The package includes two spark plugs, two plug wires, and caps, with compatibility listed for RZR XP 1000 and other RZR models.

This MOTO1988 package combines two spark plugs with two plug wires and caps, enabling buyers to replace ignition leads alongside the plugs. Its compatibility list covers several RZR 900 and 1000 variants, as well as XP Turbo and Turbo S applications across stated model years.

Replacing the wires and caps with the plugs can consolidate ignition-system parts into one purchase, rather than sourcing those listed components separately. The compatibility details name RZR XP 1000, XP 4 1000, S 1000, and Trail S 1000 variants from 2014–2023, plus other RZR lines. The supplied information also identifies iridium core and top materials. Check the exact year and model against the long application list before installation.

Skip it if you are replacing plugs only and do not need two wires with caps; this package includes both types of parts.

This kit fits buyers servicing plugs and ignition leads together on a listed RZR XP 1000, XP 4 1000, S 1000, or Trail S 1000. Verify the year and variant carefully.

#6

6. TIKSCIENCE Plug Wire Kit

• Compatible with Vehicle Type: UTV
• Core Material: Iridium
• Top Material Type: Iridium

Best for: Ignition lead replacement kit.

Why it ranks #6: This iridium plug-and-wire-cap product lists replacement numbers 4014296, 4014295, and 4017695, but its supplied fitment details are less specific.

TIKSCIENCE pairs spark plugs with wire caps, giving owners a combined option when their ignition service includes both plugs and leads. Its listed features describe high-voltage transmission through insulated wire and iridium plug materials, while the title identifies Polaris RZR 900 and 1000 family fitments.

The wire’s stated role is to carry high voltage to the plug, and its insulating material is described as helping prevent electrical leakage for stable ignition-current transmission. The plug is specified with iridium core and top materials, and the listing names replacement numbers 4014296, 4014295, and 4017695. Together, those parts support a combined replacement workflow; however, the provided compatibility details do not give model years, so check exact vehicle application before fitting.

Skip it if you need a confirmed model-year fitment list before ordering; these supplied details name no compatibility years.

Consider this for an RZR owner replacing plugs and wire caps together who can verify the listed replacement numbers against the machine. The supplied details leave model years unspecified.

#7

7. Polaris OEM 3023173

• Compatible with Vehicle Type: UTV
• Core Material: Copper
• Top Material Type: Copper

Best for: Genuine Polaris OEM choice.

Why it ranks #7: It is a genuine Polaris OEM spark plug with a one-year limited warranty, but the listing directs buyers to the owner’s manual for applicable models.

Genuine Polaris OEM status is the central reason to consider part 3023173: Polaris says its recommended plugs are selected to match the machine. That approach suits owners prioritizing a manufacturer-branded replacement, but the listing directs buyers to their owner’s manual for the specific plug type and gap.

The listing identifies this as a Polaris spark plug for select vehicle models, rather than confirming a universal RZR 1000 application. Checking the owner’s manual for the recommended plug type and gap gives buyers a route to verify whether 3023173 matches their machine before purchase. Polaris also recommends authorized-dealer installation, a relevant consideration for buyers who prefer support during maintenance. The copper core and top material are specified, but application confirmation remains essential.

Skip it if you need a listing that names your exact RZR 1000 year and trim; this one refers only to select vehicle models.

Choose this if your owner’s manual specifies Polaris part 3023173 and you want a genuine Polaris replacement. The listing does not name exact RZR applications, so verify plug type and gap first.

#8

8. Generic RZR XP 1000 Plug

Best for: RZR XP 1000 application listing.

Why it ranks #8: The nickel plug listing names RZR XP 1000 fitment for several model years, but gives less precise brand and plug-number identification than MR7F options.

The listed application for Polaris RZR XP 1000 models from 2014–2019 and 2021 gives this replacement its clearest use case. The description also names XP 1000 High Lifter, Trails & Rocks, Sport, Premium, and MD versions, helping buyers narrow the application by trim.

The application list extends beyond the standard XP 1000 to named trims and includes XP 4 1000 years, giving owners specific entries to compare with their machine. The listing describes OEM fit and function with exact dimensions and specifications intended to replace factory components seamlessly, which supports a factory-part replacement workflow. Heavy-duty alloys and reinforced composites are also claimed to resist premature wear. Match the exact trim and year, since the supplied applications are not universal.

Skip it if you have a 2020 RZR XP 1000; the listed XP 1000 years are 2014–2019 and 2021.

This is worth checking for owners of the listed RZR XP 1000 and XP 4 1000 applications who want a factory-component replacement. Confirm trim and year; the stated range is specific.

#9

9. SYKRSS CR9EIX Iridium

• Compatible with Vehicle Type: Motorcycle, ATV, Car, Truck, SUV, Marine…
• Core Material: Iridium
• Top Material Type: Iridium

Best for: Four-pack iridium option.

Why it ranks #9: This four-pack is iridium and lists some RZR compatibility among many vehicles, but the broad fitment list does not establish a specific RZR 1000 match.

A four-pack of iridium CR9EIX plugs gives SYKRSS buyers multiple replacements in one package. The compatibility list includes Polaris Ranger 900 and Ranger RZR 570 and 900 references, while the title identifies the product as an option for Polaris RZR owners.

The iridium core and top material distinguish this set from plugs specified with copper materials, and the 0.8 mm gap is a concrete specification for buyers comparing plug details. Four plugs can support keeping replacements together for ongoing maintenance, while the broad vehicle list includes several non-Polaris machines as well as Ranger RZR references. The supplied compatibility details do not explicitly identify RZR 1000, so verify the CR9EIX application for your exact machine.

Skip it if you need an explicitly listed RZR 1000 application; SYKRSS names Ranger RZR 570 and 900 references instead.

Consider this four-pack if your machine is confirmed to use CR9EIX and you want iridium plugs on hand. The listed Polaris fit references do not establish RZR 1000 compatibility.

#10

10. NGK CR9EIX Iridium

• Compatible with Vehicle Type: Car, Truck
• Core Material: Iridium
• Top Material Type: Iridium

Best for: NGK CR9EIX four-pack.

Why it ranks #10: The four-pack is a genuine NGK iridium replacement, but its listed compatible vehicle types are car and truck rather than Polaris RZR.

NGK’s genuine CR9EIX Iridium IX plugs arrive as a four-pack, enabling buyers to stock multiple replacements from the named manufacturer. The listing identifies part number 3521 and a 10 mm thread, but its stated vehicle types are cars and trucks rather than UTVs.

The iridium core and top material, together with the NGK OEM replacement description, make the product’s construction and manufacturer identity clear for buyers checking an existing plug specification. Four plugs are included, useful when a confirmed application calls for multiple replacements. However, the supplied vehicle compatibility specifies cars and trucks, and does not establish Polaris RZR fitment. Treat the CR9EIX designation as a specification to verify, not proof it suits an RZR 1000.

Skip it if you need an RZR 1000 application explicitly confirmed; NGK’s supplied compatibility lists cars and trucks.

This suits buyers whose confirmed application calls for NGK CR9EIX part 3521 and who want a four-pack. It is not established as an RZR 1000 plug by the supplied compatibility details.
