Best for: Cable-throttle cathedral-port builds.

Why it ranks #3: The 102mm manifold explicitly specifies cable-drive-only use and cathedral-port LS engines, helping buyers avoid an electronic-throttle mismatch.

The 102mm inlet is the defining feature of Htostar Racing’s LS intake, giving cable-throttle cathedral-port builds a large opening while retaining a stated 210mm height. Its listed engine range includes 4.8L and 5.3L applications as well as LS1, LS2, and LS6 engines, making head shape and throttle control the key selection checks.

Htostar specifies compatibility with cathedral-port LS heads and an LS four-bolt intake with cable drive, which helps narrow the intended installation to the appropriate engine and throttle setup. The 102mm/4.02-inch inlet provides the central sizing reference for a build using a matching throttle body. Its 210mm height is relevant when checking available under-hood clearance; the listing calls it tall. The stated vehicle applications include Corvette, Firebird, GTO, and TrailBlazer SS models.

Skip it if you need electronic throttle control; this intake is specified for cable drive, while the FAST LSXr 146302B is listed for LS1, LS2, and LS6 applications.

A cable-throttle LS owner with cathedral-port heads can use the stated engine and vehicle lists to assess this 102mm option. Check the 210mm height against available clearance, and do not choose it for a drive-by-wire setup.

• Package Dimensions: 23.2 x 13.5 x 10 in

Best for: Broad-range black LS applications.

Why it ranks #4: It lists 102mm fitment across several cathedral-port LS engine families and vehicle applications, but the supplied details say to purchase its cable-operated throttle body separately.

A 102mm opening paired with a long list of cathedral-port LS engine codes gives the YESHMA intake its clearest appeal: buyers can screen a broad range of 4.8L to 6.0L applications. The listed vehicles include Corvette, Firebird, CTS V-series, GTO, and TrailBlazer SS, while the cable-throttle body is sold separately.

YESHMA names LR4, L33, L59, LM4, LM7, LS1, LS6, LQ4, LQ9, and LS2 engines, giving a buyer concrete engine-code references before selecting an intake. The 102mm size identifies the opening, and the cable-operated throttle body can be purchased separately using the supplied product reference. This separates manifold selection from throttle-body sourcing, but means the buyer must plan that additional component. Cathedral-port heads remain the stated head configuration.

Skip it if you want the throttle body bundled with the manifold; the Haytalras 300-122 listing includes a 92mm throttle body and fuel rail kit.

This intake suits a buyer matching a listed cathedral-port engine code who wants a 102mm manifold and can source the throttle body separately. Verify the control type and account for the additional component in the installation plan.

#8

8. FAST LSXr 102mm Manifold

• Weight: 19.45 lb

Best for: Serviceable polymer LS1/2/6 manifold.

Why it ranks #8: The 102mm cathedral-port manifold supports the FAST Big Mouth throttle body or listed OEM and aftermarket 90mm and 92mm bodies, but this listing is manifold-only.

FAST’s removable-runner design lets the LSXr manifold be disassembled for porting, giving engine builders a clear maintenance and modification advantage. Longer runners and a larger-than-stock air inlet are described as adding horsepower while maintaining low-RPM torque, and the polymer body is lighter than aluminum and runs cooler.

The modular runner layout supports access for disassembly and porting, which can simplify a planned manifold modification. FAST connects the longer, less restrictive runners and larger inlet to added horsepower while retaining low-RPM torque, addressing both airflow and drivability priorities. The 102mm inlet is specified as suited to FAST’s Big Mouth throttle body, though the listing also says OEM or aftermarket 90mm and 92mm bodies can be used. It is C.A.R.B.-approved under the stated designation.

Skip it if you want a matched throttle-body kit; FAST’s LSXr 146302B-KIT bundles this manifold family with a 102mm Big Mouth throttle body.

This FAST manifold suits an LS1, LS2, or LS6 builder who values porting access, polymer construction, and stated low-RPM torque retention. Plan to source a throttle body separately and match its size to the listed inlet options.

9. Haytalras 92mm Hi-Ram Kit

• Weight: 34.3 lb
• Package Dimensions: 24.8 x 14.18 x 13 in

Best for: High-RPM cathedral-port builds.

Why it ranks #9: Its included 92mm throttle body and fuel rail kit suit a specialized Hi-Ram build, with a stated basic operating range of 3,500–8,000 RPM.

A stated 3,500–8,000 RPM operating range makes the Haytalras 300-122 a specific choice for high-revving LS cathedral-port builds. Its package combines a Hi-Ram manifold, 92mm throttle body, and fuel rail kit, giving buyers a coordinated set of named components for EFI applications rather than a manifold-only listing.

The 92mm throttle-body bore and cathedral-port configuration identify the engine-side requirements, while the 3,500–8,000 RPM range points toward a performance-oriented operating window. The included fuel rail kit and accessories shown can consolidate major intake components for installation planning. Haytalras lists 1997–2004 GM LS cathedral-port cars and trucks, including Corvette, Camaro, Silverado, Tahoe, Sierra, and Yukon models. Its 34.3-pound listed weight is worth considering when handling the assembly.

Skip it if you prioritize low-RPM operation; the FAST LSXr 146302B is described as maintaining low-RPM torque with longer runners.

The Haytalras kit fits a buyer assembling an EFI street-rod or track-oriented cathedral-port LS setup with a 92mm throttle body and fuel rails. Its specified RPM range is a meaningful boundary for builds centered on low-speed operation.

#10

10. POSENG Fabricated 102mm Intake

• Weight: 18.31 lb
• Package Dimensions: 23.15 x 14.09 x 9.76 in

Best for: Fabricated 102mm supercharger builds.

Why it ranks #10: Although it lists a 102mm opening and fuel rails, the product specifically requires a supercharger adapter and lists a different engine-family fitment from the cathedral-port options.

A 102mm opening, 203⁄4-inch total length, and 9-inch height distinguish this POSENG fabricated intake for buyers planning around its physical dimensions. The listing also specifies two high-flow fuel rails and says the manifold must be matched with a supercharger adapter, making adapter planning central to this setup.

The 3mm material thickness and TIG-welded fabrication identify the construction, while the two included fuel rails provide a stated component advantage for installation planning. POSENG lists 4.8L, 5.3L, 6.0L, and 6.2L LS engines, and the 102mm opening establishes the throttle-body size reference. The required supercharger adapter is a critical compatibility condition, not an optional detail; buyers need to include it in their parts plan before assembling this intake.

Skip it if you want a straightforward intake without a required supercharger adapter; the FAST LSXr 146302B is a manifold-only LS option.

This POSENG intake is for a buyer planning a supercharger-adapter-matched fabricated LS setup and able to work within its stated dimensions. Include the adapter in the parts plan; the listing names it as necessary for matching.
