Description

Constructed from the same advanced polymer material as the original FAST LSX 92mm Intake Manifold, but now in the popular black color, the LSXR offers a host of benefits over aluminum aftermarket intakes, including lighter weight, increased strength and improved heat dissipating characteristics. While the LSXR features a 102mm air inlet that is perfectly suited to the FAST Big Mouth 102mm Throttle Body, for maximum convenience it can also be used with OEM or aftermarket 90mm or 92mm throttle bodies. Other features include integrated nitrous bungs and perfect bolt-on fitment that allows the use of factory accessories without modification or clearance concerns. Fits most C5 and C6 Corvettes without modification.

Aside from shipping taking extremely longer than normal due to snow delays. they always come thru with quality. Best intake on the market for you LS. Do your own research. great price and bang for your buck kit on Amazon!

Very misleading

Does not come with the hardware to install the intake. One review said it did but it does not. Make sure to click “what’s in the box” it’ll only state manifold. Poor husband is now doing research to find the correct hardware because the pictures and the description showing the manifold with the hardware. Instruction manual states it comes with hardware but upon further inspection there’s grease all over it and and bolt sticking out. Will be returning if we can’t get this resolved!! ... show more

I bought this and was fairly happy. It comes with everything Hardware wise to be installed. I got it from summit racing so I only want to inform people of what else is needed to go with this. First the obvious, the 102 mm throttle body which runs in the $400 range, Next was the fuel injectors part# 306000 from FAST or Summit racing, That's about $475. Next we have the after market fuel rails which run you about $150 and includes all the things you need. Then you need the fuel injector adapter kit harness that lets you plug in your new FAST fuel injectors with the stock electric harness on your car because they are very different(ev1 to ev 6 I believe). That's about $90. Point is if you buy this plan on spending a lot more to get the things needed to make this work on your car. I have a 2011 camaro ss and after install, the electric actuator of the throttle body sits way to close to my tension pulley for my belt. I'm talking like 1 to 2 cm away. its really close so I thought of flipping the throttle body around but we will see. ... show more

Bull s***.. I bought this manifold with NW 102 throttle body and installed them on my ls3 cammed camaro, then I lost HP instead of gaining it :( So DON'T bother and waste your money ..
