FAST LSXr 102mm 吸気マニホールド LS1、LS2、LS6用 (146302B) ブラック

I got this for my 2006 Pontiac GTO. It's a good DIY upgrade and bolts right on. Only modification necessary is to drill a little hole for the MAF, otherwise it goes right in. I'd recommend getting new gaskets while you're in there. As soon as it was installed, I noticed my car pulled harder in 3rd and 4th gear. Definitely would recommend.

I used to have one of these intake manifolds on my LS1. Years ago I started the process of turbocharging my car and I must have bumped my head on something because I sold it and bought a Holley intake. While Holley does make a nice intake I missed the Fast intake as I felt it was more appropriate for my build. The " best usable" RPM range of the Fast is around 2-7k rpm, exactly where my engine makes power best. It's lightweight, won't heatsoak, and its very well made. For a cathedral port LS engine I firmly believe that this is a solid upgrade. I'm running a 92mm throttle with a velocity ring (which unfortunately can be difficult to find nowadays), and 10lbs of boost. I made sure to follow the directions exactly when installing, boost leak tested it up to 20psi, and did not have a single leak. I'm very happy to have a Fast intake again, the car is running great and making some good power.

Be wary about purchasing through this seller. Had a price error and everyone who ordered got the same "it was damaged in transport" email. Didn't give me the option to wait for another replacement and when the refund was issued they took the money out again. WATCH OUT !!!

You can definitely tell a difference, it took me 2 weekend's to install with a bad back. I installed on a C6 corvette. Easy install, I just watched YouTube videos and not one problem. I would definitely spend the money on the FAST gaskets. Take pics of all your hose connections and should be breeze. I'm running stock air box, stock TB. X4 tune and mainfold together sings very well.

Be prepared to spend some extra money on miscellaneous parts that dont come with it. Bought this after using a FAST 92 intake, which is very good. This is just better, and with a 102mm tb, the airflow is incredible. Picked up power all the way through the RPM range.
