Best Intake For Holley Sniper Efi: 8 Manifolds Compared

#1 · Best Overall

1. Holley Sniper EFI 822112-1

• Weight: 17.5 lb

Best for: Low-clearance Sniper builds.

Why it ranks #1: Its name explicitly identifies Sniper EFI, and its low-profile design is the closest stated match; engine application details still need confirmation.

The low-profile sheet-metal fabricated construction is the key feature of Holley’s 822112-1, giving buyers an intake option when vertical clearance matters. Its listed dimensions are 21.25 by 14.5 by 10 inches, and the low-profile designation helps distinguish it from taller Hi-Ram choices in this lineup.

The low-profile form is the practical reason to consider this manifold for a build where space above the engine is a concern; the listing also gives its dimensions as 21.25 by 14.5 by 10 inches, so buyers have a concrete size reference for planning. Holley identifies the product as a fabricated intake manifold, but the supplied details do not state an engine family, port measurements, or throttle-body size. Treat those application details as unresolved before selecting it for an EFI setup.

Skip it if you need a stated LS application, port dimensions, or throttle-body size; the supplied listing does not identify those specifications.

This is the most directly Sniper-named option here for buyers prioritizing a low-profile manifold and a defined overall size. Its listed details leave engine-family and throttle-body compatibility unanswered, so those requirements should guide the final selection.

#2 · Best LS Single Plane

2. Holley 300-137 Single Plane EFI

• Weight: 6.3 kg

Best for: Higher-rpm LS EFI builds.

Why it ranks #2: The listing specifies GM LS1, LS2, and LS6 fitment, EFI use, and a 2,500–7,000 RPM range, though not Sniper compatibility.

Holley’s 300-137 is a single-plane EFI intake with a stated 2,500-to-7,000-rpm range, making its operating band the clearest selection point. It is identified for GM LS1, LS2, and LS6 applications, with port dimensions and sensor-port threads that aid build planning.

The 2,500-to-7,000-rpm range makes this manifold a candidate for buyers whose intended engine operation falls within that stated band. Its LS1, LS2, and LS6 application identifies the engine family, while the 2.66-inch-high by 0.92-inch-wide ports give a measurable reference for the intake side. A 3/8-inch NPT vacuum port and 1/8-inch NPT MAP sensor port specify connection threads, helping buyers plan sensor and vacuum plumbing rather than guess at those interfaces.

Skip it if you need a Hi-Ram intake with a stated 92 mm throttle body; Holley’s 300-116 lists that configuration.

This intake fits LS1, LS2, or LS6 builders targeting the stated 2,500-to-7,000-rpm range and needing specified vacuum and MAP port threads. Its single-plane format and operating band should suit the engine’s intended use.

#3 · Best 92mm Hi-Ram

3. Holley 300-116 Hi-Ram

• Weight: 34 lb

Best for: 92 mm LS Hi-Ram setup.

Why it ranks #3: This EFI Hi-Ram lists a 92 mm GM LS throttle body and LS3-style molded O-ring gasket type, useful details for matching LS components.

Holley’s 300-116 pairs a Hi-Ram EFI intake with one 92 mm GM LS throttle body, giving a build a clearly stated throttle-body size and LS-oriented configuration. Its listed port dimensions and flange height provide useful planning references for buyers evaluating engine packaging and intake fit.

The base plenum top mounting flange sits 8.42 inches above the engine block’s lifter-valley cover flange, a measurement that helps assess vertical space before installation. Port size is listed as 2.49 inches high by 1.21 inches wide, providing a concrete reference for matching the intake to the engine-side setup. The supplied mounting-flange gasket type is a standard LS3 molded O-ring. Together, these details make fit planning more specific, though the stated single 92 mm GM LS throttle body remains the application-defining choice.

Skip it if you need a 102 mm throttle-body configuration; Holley’s 300-117 is listed with a 102 mm GM LS throttle body.

The 300-116 suits LS builders who want a Hi-Ram EFI intake with a specified 92 mm GM throttle body and useful height and port measurements. Check those dimensions against the engine and available space before choosing it.

#4 · Best LS3 Option

4. Holley 300-290 LS3 EFI

• Weight: 20 lb

Best for: Corrosion-conscious LS3 builds.

Why it ranks #4: The product title identifies an LS3 split single-plane EFI intake, making its stated engine family more specific than most other listings.

Holley identifies this intake as an LS3 split single-plane EFI manifold and specifically lists corrosion resistance, giving buyers both an application cue and a material-care consideration. Its listed 11-by-15-by-21-inch dimensions offer a useful package-size reference for installation planning.

The LS3 designation and split single-plane EFI description make the intended engine and intake style clear, helping buyers screen it against their build before installation. Holley also lists corrosion resistance, quality materials, easy installation, and durable, long-lasting construction; those stated attributes support a practical focus on upkeep and fitting. The dimensions are 11 by 15 by 21 inches and weight is 20 pounds, useful figures for handling and space planning, but the listing does not provide port or throttle-body measurements.

Skip it if you require stated port and throttle-body measurements; Holley’s 300-137 lists port dimensions and sensor-port threads.

This manifold suits LS3 buyers seeking a split single-plane EFI intake with stated corrosion resistance and installation ease. Its listed dimensions help with space planning, but buyers needing port or throttle-body specifications should account for those unanswered details.

#5

5. Holley 300-122 LS Hi-Ram

• Weight: 35 lb

Best for: Modular LS Hi-Ram systems.

Why it ranks #5: It is an EFI Hi-Ram system for LS1, LS2, and LS6 with a stated 92 mm throttle body, but the listing does not identify Sniper fitment.

Holley’s 300-122 is a modular LS Hi-Ram EFI system with a listed 92 mm throttle body, giving LS1, LS2, and LS6 builders a defined throttle-body and engine-family starting point. Its stated broad power range and race styling make the intended performance-oriented character clear.

The modular Hi-Ram system label identifies an intake built around a modular configuration, while the listed 92 mm throttle body gives buyers a specific size to consider when planning the EFI setup. Holley names LS1, LS2, and LS6 use, which narrows the application rather than leaving engine family open-ended. The product also cites broad power range and aggressive race styling, useful cues for a performance build, though the supplied facts do not give a numerical operating range or detailed module contents.

Skip it if you need a stated operating RPM band; Holley’s 300-137 lists a 2,500-to-7,000-rpm range for LS1, LS2, and LS6.

The 300-122 suits LS1, LS2, and LS6 builders seeking a modular Hi-Ram system with a stated 92 mm throttle body. Consider its non-numerical power-range description when a precise operating band is essential.

#6

6. Holley 300-117 Hi-Ram

• Weight: 15.45 kg

Best for: Large-throttle-body LS Hi-Ram.

Why it ranks #6: The listing describes an LS3/L92 Hi-Ram kit and gives a 102 mm throttle body in its title, but another description says 105 mm.

Holley’s 300-117 is titled as a Hi-Ram EFI manifold with one 102 mm GM LS throttle body, a concrete differentiator for buyers choosing a large-throttle-body setup. The listing also supplies overall length and width, helping builders begin packaging checks around the intake.

The titled 102 mm GM LS throttle body and Hi-Ram EFI description identify the central configuration, so buyers can compare it with their planned LS induction setup. Holley lists dimensions of 26.3 inches long by 14.6 inches wide, which support preliminary packaging checks before the manifold reaches the engine. Additional description identifies an aluminum, natural-finish, multi-port, rectangle-port kit for LS3/L92 and GM LS-series applications, while the supplied material does not clearly reconcile its separate 102 mm and 105 mm flange wording.

Skip it if you need a 92 mm configuration with detailed port and gasket specifications; Holley’s 300-116 lists those details.

The 300-117 suits LS builders pursuing a Hi-Ram arrangement and a 102 mm GM LS throttle body, with dimensions for initial packaging review. Resolve the listing’s 102 mm versus 105 mm flange wording before settling on the setup.

#7

7. Holley 300-122BK Left Side Hi-Ram

• Weight: 24 lb

Best for: Left-side modular Hi-Ram builds.

Why it ranks #7: This is a left-side version of the LS Hi-Ram system, but its supplied specifications do not state engine application or throttle-body size.

Holley’s 300-122BK is specifically identified as a left-side Hi-Ram modular intake system, making its orientation the key selection detail. That configuration can guide buyers whose planned engine layout calls for the listed left-side system, while its 24-pound weight helps with handling preparation.

The left-side designation separates this 300-122BK from a generic Hi-Ram listing and gives builders an orientation detail to check against their intended layout. Its modular Hi-Ram system identity points to the product configuration, while the 24-pound listed weight is useful when planning handling during installation. The supplied facts do not identify engine-family fit, throttle-body size, port measurements, or included system modules, so buyers should not infer those specifications from the model name alone.

Skip it if you need a stated LS application and 92 mm throttle body; Holley’s 300-122 lists LS1, LS2, LS6, and 92 mm.

The 300-122BK is for buyers whose layout calls for a left-side modular Hi-Ram system and who can verify the remaining application details independently. Its listing gives no engine family or throttle-body size, important boundaries for EFI planning.

#8

8. Edelbrock 7501 Performer RPM

• Weight: 8.77 kg

Best for: Air-gap dual-plane builds.

Why it ranks #8: Its listing says it is meant for square-bore carburetors, not a Sniper EFI setup, so it is the least direct match in this selection.

Edelbrock’s Air-Gap design separates the intake runners from heat at the lifter-valley cover, a layout intended to help keep the incoming charge cooler and denser. The 7501 is a dual-plane manifold for square-bore carburetors, making its carburetor-oriented application central to any EFI buyer’s decision.

The dual-plane layout and Air-Gap space give this manifold its defining arrangement: the runners are separated from the hot lifter-valley area, which the supplied description connects with a cooler, denser charge. A temperature-sending-unit boss clears all water necks, helping preserve that installation point. The listing specifically states square-bore carburetor use and no exhaust-heated choke or crossover provision, so it is not presented as a direct Sniper EFI intake; the stock Corvette hood limitation also matters for fit.

Skip it if you want a listed EFI throttle-body intake; Holley’s 300-137 is explicitly an EFI manifold for GM LS1, LS2, and LS6 engines.

Choose the 7501 only if its square-bore carburetor application suits the build and the Air-Gap layout is the priority. It is a poor match for buyers seeking a clearly specified Sniper EFI manifold, and stock Corvette hood clearance is restricted.
