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

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.

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.

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 !!!

I have an 06 Corvette with an LS2 and I was getting a continuous check engine light because of lean codes on both banks because of an internal air leak with the stock manifold. I was going to buy the Dorman manifold which is a couple of hundred less but opted for this manifold because of the so called power increase. It also has a cool look and I thought that it would be a good selling feature when I sell the car. I'm an ASE certified master auto technician and I would rate this as a tricky installation. It has to be drilled out for the MAP sensor and the harness will also have to be extended. I was surprised that for this much money the intake port gaskets weren't included. I think that if I were going to do this again I would go with the Dorman manifold.
