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.

Holley EFI LS Single Plane Split-Design Race Intake Manifolds

Developed with performance in mind, Holley EFI LS single plane split-design race intake manifolds feature a race bred, 2-piece split design that was previously found only on the most expensive race intakes. These manifolds will fit GM LS Gen III engines with cathedral port heads for high performance/racing engine applications with 5.3 to 6.2 liter displacement and maximum engine speeds of 6,000 to 7,000 rpm, depending on the engine combination. The single-plane design provides optimal performance across the rpm spectrum, while the split feature, which allows disassembly of the intake for direct access to internal plenum and port surfaces, makes custom porting and matching a snap. Shoulder bolt locators and an O-ring seal makes reassembly simple and precise.

Holley EFI LS Hi-Ram Intake Manifold Bases

Holley EFI LS Hi-Ram intake manifold bases are cost-effective alternatives to fabricated sheet metal for high performance applications where induction system height is not limited. Coupling these cast aluminum Hi-Rams with the high flowing LS-style cylinder heads has outstanding potential for N/A and forced induction applications at a budget-minded cost. These modular lower manifolds accept a wide range of carbureted and EFI tops, making them attractive to builders and fabricators as the perfect foundations for custom induction systems. Fuel rails are included and machined for -8 AN O-ring fittings with passages large enough to accommodate high fuel flows and dampen pressure pulsations in the fuel system. The aggressive, bold, race-bred styling of Holley GM LS modular Hi-Ram lower manifolds will make bad intentions clear for drag race, muscle car, marine, off-road, sand rails, pulling trucks, track, and street-rod applications.
