Best Spark Plugs For Mazda Cx 5: 10 Options Compared

#1 · Best Overall

1. Sixity Auto NGK Laser Iridium

• Core Material: Iridium
• Compatible with Vehicle Type: Car, Truck
• Gap Size: 0.04 in

Best for: NGK Iridium Replacement Set.

Why it ranks #1: Lists genuine NGK iridium plugs for CX-5 2.0L and 2.5L L4 models from 2013–2020, with a set of four plugs and a 0.04-inch gap.

Laser iridium construction and a four-plug set make this NGK option a direct replacement candidate for listed 2013–2020 Mazda CX-5 2.0L and 2.5L four-cylinder engines. Its center and ground electrodes focus the spark, a feature intended to help reduce misfires while supporting consistent ignition across the set.

The listed CX-5 fitment covers both 2.0L and 2.5L L4 engines from 2013 through 2020, giving owners of those specified configurations a clear application range. Iridium is the stated core material, while the center and ground electrode design promotes sharper spark focus; the product description connects that geometry with fewer misfires. A durable shell is also described as protecting the plug, supporting continued sparking. The package contains four plugs for a set replacement.

Skip it if you own a CX-5 outside the listed 2013–2020 range; SYKRSS 94124 lists CX-5 coverage through 2023.

This set suits owners of listed 2013–2020 CX-5 2.0L or 2.5L L4 models seeking NGK laser-iridium plugs. Its stated CX-5 coverage does not extend beyond 2020, so later models fall outside this listing’s specified range.

#2 · Genuine Mazda Set

2. Mazda PE5R Iridium Plugs

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

Best for: Genuine Mazda Plug Set.

Why it ranks #2: Genuine Mazda iridium plugs include four pieces and list CX-5 among compatible models; the supplied fitment detail should be checked for the exact vehicle.

Genuine Mazda PE5R-18-110A iridium plugs provide an original-brand option for owners prioritizing Mazda-supplied components. The four-plug set lists CX-5 among its compatible models and also names Mazda3, Mazda6, CX-3, and MX-5 Miata applications, making the fitment details central to choosing it.

Mazda Motor Corporation is the listed brand, and the plugs use an iridium core, pairing an OEM-branded part with the stated electrode material. The four-piece set is listed for several Mazda families, including CX-5, while the supplied fitment information also specifies particular years and engine configurations for other models. Its replacement references include several PE-series numbers, which can help buyers comparing an existing Mazda plug reference with this set.

Skip it if you need a clearly stated CX-5 year and engine range; Sixity Auto NGK plugs list 2013–2020 2.0L and 2.5L L4 coverage.

This set fits buyers who want a Mazda-branded iridium option and can match the PE5R-18-110A reference to their CX-5. The supplied listing names CX-5 but does not provide its year or engine details here.

#3 · Broad CX-5 Fitment

3. SYKRSS 94124 Iridium Plugs

• Core Material: Iridium
• Compatible with Vehicle Type: Car, Truck, Motorcycle
• Gap Size: 0.04 in

Best for: Broad-Mazda Iridium Four-Pack.

Why it ranks #3: Lists compatibility with Mazda CX-5 from 2014–2023, uses iridium, and specifies a 0.04-inch gap and a two-year manufacturer warranty.

A four-pack of 94124 iridium spark plugs combines a CX-5 application list spanning 2014–2023 with coverage for several other Mazda models. That broad range helps owners cross-reference family and year, while the specified 14mm thread and 0.04-inch gap provide concrete plug dimensions.

Iridium is listed as both the core and top material, and the 0.04-inch gap gives buyers a stated setup specification to compare with their vehicle requirements. The compatibility list includes CX-5 models from 2014–2023, plus Mazda3, Mazda6, CX-3, CX-30, CX-50, and MX-5 Miata. A four-pack supplies a complete set for a four-cylinder application, while the listing also names Scion iA and Toyota Yaris fitments.

Skip it if you have a 2013 CX-5; Sixity Auto NGK Laser Iridium plugs list 2013–2020 CX-5 fitment.

This pack suits owners of listed 2014–2023 CX-5 models who want iridium plugs with stated thread and gap dimensions. Its CX-5 fitment begins in 2014, so the listing does not cover 2013 models.

#4 · 94124 Alternative

4. BDFHYK 94124 Iridium Plugs

• Core Material: Iridium
• Compatible with Vehicle Type: Car
• Gap Size: 1.1 millimeters

Best for: 94124 Iridium Four-Pack.

Why it ranks #4: Lists Mazda CX-5 compatibility from 2014–2023 and iridium construction; the listing specifies a 1.1-millimeter gap and a one-year warranty.

BDFHYK’s 94124 iridium set lists CX-5 coverage from 2014–2023 and specifies a 1.1-millimeter gap. That combination gives buyers a stated compatibility window and gap dimension to check against their service needs, in a four-plug set also listed for other Mazda models.

The compatibility list names CX-5 alongside Mazda3, Mazda6, CX-3, CX-30, CX-50, and MX-5 Miata, plus Scion iA and Toyota Yaris applications. Iridium is specified for the core and top material, while the listed 1.1-millimeter gap makes the plug’s setup dimension explicit. The four-piece quantity supports a complete set replacement, and the product description characterizes its ignition jump as faster and more sensitive.

Skip it if you own a 2013 CX-5; Sixity Auto NGK plugs list CX-5 fitment beginning in 2013.

This is a relevant option for owners of CX-5 models within the listed 2014–2023 span who want a four-pack with a stated gap. Its supplied CX-5 range excludes 2013, which is a clear fitment boundary.

#5 · Turbo CX-5 Option

5. OverstockDirect NGK 90288

• Core Material: Iridium
• Gap Size: 0.03 in

Best for: Turbo CX-5 Laser Iridium.

Why it ranks #5: The listed DILKAR7M8 plug is compatible with CX-5 2.5L turbo models from 2019–2024 and comes as a four-plug iridium set.

NGK Laser Iridium DILKAR7M8 plugs specifically list 2019–2024 Mazda CX-5 2.5L turbocharged applications. The four-pack and 0.03-inch gap give turbo owners a narrowly targeted option with clear plug dimensions, while the same listing covers other named Mazda turbo models.

This set contains four NGK 90288 Laser Iridium plugs, and its supplied vehicle list specifies CX-5 2019–2024 with a 2.5L turbocharged engine. The 0.03-inch gap and 12.0mm thread size provide concrete specifications for application checks. NGK is identified as an OEM spark-plug supplier, and the listing describes its Laser Iridium plugs as high-ignitability, making this more targeted than a general CX-5 fitment listing.

Skip it if you drive a naturally aspirated CX-5; SYKRSS 94124 lists broader CX-5 coverage across 2014–2023.

Choose this four-pack for a CX-5 2.5L turbocharged model in the listed 2019–2024 range, especially when matching the specified gap and thread. Naturally aspirated CX-5 applications are outside its stated fitment.

#6

6. A-Premium Double Iridium

• Core Material: Iridium

Best for: Fine-Wire Turbo Plug Set.

Why it ranks #6: Fits listed CX-5 2.5L turbo models from 2019–2020, with a 0.030-inch gap and double-iridium electrode materials.

A-Premium’s double-iridium fine-wire plugs list turbocharged CX-5 2.5L fitment for 2019–2020 and a 0.030-inch gap. The pack of four targets owners seeking a turbo-specific replacement, with the same reference number as NGK DILKAR7M8 named in the listing.

The listing specifies iridium for both the center electrode tip and core, while the double-iridium designation identifies the electrode material approach. Its vehicle details cover CX-5 2019–2020 2.5L turbocharged models and also list other Mazda turbo applications. A stated 0.030-inch gap gives buyers a useful specification to compare, and the four-piece pack supplies a full set for the listed four-cylinder engine configuration.

Skip it if you have a 2021–2024 CX-5 turbo; NGK DILKAR7M8 lists turbo CX-5 coverage through 2024.

This set fits buyers with a listed 2019–2020 CX-5 2.5L turbo who want double-iridium plugs and a defined gap. Its CX-5 range ends in 2020, so later turbo models are outside the supplied fitment.

#7

7. X4XZ Coil and Plug Kit

• Compatible with Vehicle Type: Car

Best for: Coil And Plug Repair Kit.

Why it ranks #7: Includes ignition coils and double-iridium plugs and lists CX-5 compatibility from 2013–2018, but is a combined replacement kit rather than plugs alone.

A combined ignition coil and double-iridium spark plug package addresses both components in one repair kit for listed 2013–2018 Mazda CX-5 applications. The included parts target ignition-system replacement together, while the fitment list also covers several Mazda car lines for buyers sourcing a broader compatible set.

This kit includes an ignition coil and double-iridium spark plug, so a buyer addressing both components can source them together rather than assembling separate parts. The listing identifies CX-5 fitment from 2013–2018 and names additional Mazda models, including Mazda3 and Mazda6. Its description links faulty coils and plugs with misfires, rough idle, reduced power, and poor fuel economy; it also says components match or improve on OE design for installation.

Skip it if you need only spark plugs; NGK Laser Iridium DILKAR7M8 is a four-plug set for listed turbo CX-5 models.

Choose this package when replacing a coil and plug together on a CX-5 within its listed 2013–2018 range, or another named Mazda application. It is a combined repair kit, so it is not the focused choice for plug-only service.

#8

8. A Plus Auto Coil and Plug Kit

Best for: Four-Coil Ignition Refresh.

Why it ranks #8: Includes four ignition coils and four spark plugs and lists CX-5 fitment from 2013–2025; the listing advises checking confirmed fitment.

Four ignition coils plus four spark plugs make this A Plus Auto package a broad ignition refresh kit for listed Mazda CX-5 models. Its fitment spans CX-5 years 2013–2025, alongside several other Mazda lines, giving owners a single package when replacing both ignition components.

The included components are four ignition coils and four spark plugs, so the package covers all four positions with both component types. Its listed Mazda CX-5 range runs from 2013 through 2025, with additional coverage for Mazda3, Mazda6, CX-3, CX-9, CX-30, CX-50, and MX-5 Miata. The listing also provides interchange numbers such as UF656 and UF805, useful when comparing the kit with a prior component reference.

Skip it if you are replacing plugs alone; Bosch 9621 is a four-plug set without coils in its listed components.

This kit suits CX-5 owners planning a full four-cylinder coil-and-plug replacement within the listed 2013–2025 span. Its four coils expand the job beyond spark plugs, so it is less suitable for a plug-only maintenance visit.

#9

9. BELKEBIR UF656 Coil Kit

• Compatible with Vehicle Type: Car

Best for: Plug And Coil Set For Mazda.

Why it ranks #9: Bundles four coils and four iridium plugs and lists CX-5 compatibility across several engine-year combinations, including 2.0L and 2.5L variants.

A plug-and-play package containing four ignition coils and four iridium spark plugs gives this BELKEBIR kit a complete replacement focus. Its extensive Mazda compatibility list includes CX-5 configurations from 2013 onward, with engine-specific qualifications such as 2.5L models without cylinder deactivation.

The four coils and four plugs arrive together, making the set relevant when both ignition components are part of the service rather than plugs alone. The listing specifies CX-5 applications including 2013 2.0L and several 2.5L ranges, with cylinder-deactivation qualifications on some entries. Its stated plug-and-play installation type supports a standard installation workflow, while the broad list also includes Mazda3, Mazda6, CX-3, CX-30, and MX-5 Miata.

Skip it if you have a CX-5 2.5L with cylinder deactivation; the listing qualifies some 2.5L applications as without it.

Consider this kit when servicing coils and plugs together on a CX-5 configuration specifically covered by its detailed list. Because some 2.5L entries exclude cylinder deactivation, that engine qualification is an important boundary.

Listed on Amazon as: Set of 4 Ignition Coil Packs & Iridium Spark Plugs Compatible with 2.0L 2.5L 2012-2019 Mazda 3, 2016-2018 3 Sport, 2014-2017 Mazda 6, 2016-2020 CX-3, 2013-2018 CX-5, 2016-2018 MX-5 Miata Replace UF656

#10

10. Bosch 9621 Double Iridium

• Core Material: Iridium
• Compatible with Vehicle Type: Car, SUV, Truck
• Gap Size: 0.04 in

Best for: Double-Iridium Long-Life Set.

Why it ranks #10: Offers double-iridium construction and a 0.04-inch gap, but the supplied listing does not specify Mazda CX-5 fitment, so verify its application first.

Bosch’s double-iridium design places iridium at both the firing pin and ground electrode, with a stated four-times-longer life than standard copper plugs. The four-pack also uses an ultra-fine wire firing pin that the listing says reduces voltage requirements by up to 24%.

The iridium firing pin and ground-electrode inlay combine two iridium elements, while Bosch’s 360-degree laser-welded ultra-fine wire is associated with better ignitability and up to 24% lower voltage requirements. Nickel-plated rolled threads are described as resisting corrosion, supporting easier removal over time. These details make the set appealing for buyers weighing ignition demand and service maintenance, though the supplied information does not state CX-5-specific fitment.

Skip it if you need a listed CX-5 application; NGK Laser Iridium DILKAR7M8 specifies turbo CX-5 years and engine configuration.

Bosch’s set suits buyers prioritizing double-iridium construction, reduced voltage demand, and corrosion-resistant threads. The supplied details do not identify a CX-5 application, so treat it as a candidate only when its specifications match your vehicle.
