FAST LSXr 102mm Intake Manifold for LS1, LS2, and LS6 (146302B), black

It came super early and the packaging was SUPERB. This will give you amazing gain, especially if you have other intake mods to go with it. The instructions are very instructional. One big tip is to make sure that you use the provided throttlebody bolts. The stock ones are too long and they will screw through the body of the intake and damage it.

No extra parts needed, fuel rails worked perfect along with injectors. If you have a ls 1 or 6 then you'll need to have additional parts.

Fits perfect on my ls1 engine. I got a 2000 camaro Z28. Yes, the other reviews are accurate about the fuel rails and other adjustments, but this intake manifold is a beast

C6 LS2... With my tune..the mid range pull is awesome!!!If you have an LS2 it will bolt right on!! Everything from your LS2 will fit perfectly..

c5 ls1 install going at 2 weeks currently a lot of trial and error. Ordering parts is destined but they dont tell you every part you need. Hoping i dont have to cut into my windshield wiper tray to make room.

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.

I like it

i am very disappointed with this manifold. first of all the fact that you have to drill holes for sensor mounting in a piece that cost almost a thousand dollars is just nuts. i replaced my stock ls2 manifold with this per comp cams website because they said it is REQUIRED with the xr281 cam i installed. so for fun i had the car tuned and dyno tested with the stock ls2 manifold still installed and it produced 397rwhp with my other supporting mods. i was pretty happy with these numbers but wanted just a touch more and hoped the lsxr would tip me over the 400 hp mark. so next off the only change i made was installing the fast lsxr 102 and i again had it re-tuned and dyno tested. i was expecting to see a small gain in hp and torque. much to my surprise the second time around on the dyno i lost horsepower at 394 compared to my previous 397 and my torque went down also.. i extremely disappointed with this highly overpriced and over-hyped chunk of plastic
