FAST LSXR Intake Manifolds

The engineers at FAST teamed up with the airflow specialists at RHS to develop a 3-piece, polymer intake manifold. They are constructed from a proprietary advanced polymer material that offers a host of benefits over aluminum aftermarket intakes, including lighter weight and improved strength and heat dissipating characteristics. While they feature a 102mm air inlet that is perfectly suited to the FAST Big Mouth 102mm throttle body, they can also be used with stock or aftermarket 90mm or 92mm throttle bodies. Other features include integrated nitrous bungs and perfect bolt-on fitment that allows for the use of factory accessories without modifications or clearance concerns. FAST LSXR intake manifolds' 3-piece modular design allows for easy disassembly and porting. This new design gives you the ability to remove individual runners from the manifold for modification.

FAST LSXRT Intake Manifolds

FAST LSXRT intake manifolds are designed specifically for GM truck engines (4.8L, 5.3L, and 6.0L) and LS1, LS2, and LS6 race applications where hood clearance is not a concern. FAST LSXRT 102mm intake manifolds follow the path chartered by the original FAST LSX Gen III intakes by featuring a modular design that allows for easy porting and disassembly and a runner design that yields an incredible 25 peak horsepower gain over the stock intake (on a stock 6.0L engine with a Big Mouth 102mm throttle body). Similar to the LSXR 102mm intake manifold for cars, the LSXRT features the ability to remove individual runners for modification. LSXRT's are constructed from a proprietary precision injection molded polymer which offers many benefits, including lighter weight, greater strength and lower heat soak propensity. While they feature a 102mm air inlet that was designed for the FAST Big Mouth 102mm throttle body, they can also be used with stock 90mm or aftermarket 92mm throttle bodies (78mm three-bolt throttle bodies require an adapter). Other features include integrated nitrous bungs and precise bolt-on fit that permits the use of factory accessories and OEM fuel/emission connections without adjustments or clearance issues. Some GM truck models may require the FAST 92mm or 102mm throttle body.

Holley EFI LT1 Gen V Hi-Ram Intake Manifolds

Holley EFI LT1 Gen V Hi-Ram intake manifolds provide the ultimate performance with GM direct-injected Gen V 6.2L LT1 engines. The modular design allows easy disassembly for custom porting, multiple tops, or custom induction systems. Each runner has a large radius where it meets the plenum, and optimized taper and cross-sectional area to perform in a wide variety of engine configurations. When you look for the pinnacle of performance, price, and quality, look to Holley Hi-Ram intake manifolds for your LT1 application. Features include: * Available with injector bosses on the intake runners that provide increased performance potential by using additional injectors and the factory direct injection * Removable top * Large plenum volume * Intakes with injector ports include fuel rails with dual mounting * Fuel rails are anodized, laser-etched, and machined for -8 AN O-ring fittings at each end * Rear of plenum machined for MAP sensor and three vacuum ports * Head flange has clearance for fuel supply to a high-pressure pump * Increased runner wall thickness for custom porting at the plenum to runner entry on each runner * O-ring seals at cylinder heads and plenum top * Easy assembly with top-mounted screws on plenum top (except front two screws) * Several top options: 1 x 95mm, 1 x 105mm, 2 x 4150, 2 x 4500, or blank flange for custom throttle bodies * 3,500 to 8,000-plus rpm power band

Edelbrock Victor II EFI Chrysler HEMI Intake Manifolds

Edelbrock Victor II EFI Chrysler HEMI intake manifolds are designed for the later model Eagle or WT versions of Chrysler 5.7L, 6.1L, and 6.4L Gen III HEMI passenger car engines (with stock fuel injectors). They are similar in design to the early factory 6.1L SRT models but incorporate a wider plenum with long tapered runners, increasing airflow to the head, and relocated injector bosses to decrease port restriction. The front inlet accepts stock 80mm or Hellcat 92mm OEM throttle bodies and features the 5.7L/6.1L throttle body location/orientation. Edelbrock Victor II EFI Chrysler HEMI intake manifolds will clear most hoods without modifications and provide increased horsepower over stock units. Additional information: * Nitrous bosses added along the near-vertical runners * OEM or OE-style replacement air intake system must be used on 5.7L/6.1L engines. The 6.4L engines require OEM or OE-style 6.1L intake systems (without intake runner control valve) as stock and aftermarket 6.4L air intake systems will not fit * EDL-3647 fuel rail and hose kit are required for installation (sold separately) * Calibration required after installation * Not intended for use on Dodge/Ram trucks
