The wheels of government move slowly, but with enough patience, sometimes you get the result you hoped for… We’re happy to announce that the very popular FAST LSXR 102mm manifold has passed California Air Resources Board testing and has been issued Executive Order number D-279-7, making it street legal for the entire US of A. All three LSXR 102mm part numbers are covered – 146102 for LS3/L76/L92/L99 rectangular port applications, 146202 for LS7 raised port engines, and 146302 for good old cathedral-port LS1/LS2/LS6 powerplants.
These intakes feature a 102mm throttle body opening, though they are compatible with 90/82mm throttle bodies as well, and OEM 75mm LS1/2/6 throttle bodies when the PN 146029 adapter kit is used. When paired with a FAST 102mm Big Mouth throttle body, gains of as much as 16 horsepower on a stock-displacement engine are possible, but big-cube applications are where this manifold really shines.
The modular design of the FAST LSXR intake means that the individual runners can be ported or modified for racing applications – needless to say, this voids the EO number, but for street use where emissions are a concern, the straight-out-of-the-box manifold will provide a big bump in performance.
