Unlock Maximum LS Power with FAST LSXR Intake Manifolds

Whether you’re rocking a high horsepower street-driver or chasing lower ETs at the track, FAST LSXR Intake Manifolds deliver the big dose of airflow needed to get the most power possible from your fire-breathing GM LS.

At the core of every LSXR manifold is a 102mm throttle body inlet paired with optimized runners that maximize airflow velocity and distribution. The three-piece modular design allows you to remove the individual runners for porting or swapping to a different runner set. This flexibility allows you to shift power and torque curves to better suit your combination. Integrated bungs make it easy to plumb a direct-port nitrous system, further expanding power potential.

Unlike aluminum aftermarket manifolds, the LSXR manifolds’ proprietary advanced polymer construction resists heat soak, keeping the incoming air/fuel charge cooler. This boosts air density for making consistent power. It also makes the manifolds significantly lighter and stronger than aluminum manifolds.

On the dyno is where the LSXR manifolds really shine. Stock or mildly modified engines typically net a 10 to 18 horsepower improvement just by swapping the factory manifold for an LSXR manifold. If the engine has been modded with improved heads and a cam, gains of 25 to 40-plus horsepower can be expected. Add a bunch of boost and you can see the power numbers swell by 50 or more.
 
Designed as a true bolt-on upgrade, FAST LSXR Intake Manifolds are compatible with factory accessories and connections without creating hood clearance issues (most applications). The manifolds are available individually or in kits that include a 102mm Big Mouth Throttle Body to fit most late model LS engines with cathedral or round port cylinder heads
