Do they really work like they say gaining 20hp and like 40 lbs of torque?

 

Chop the zeros off those numbers and I might believe it. Especially on a stock engine.

 

I dont know how much the numbers changed, but I could feel a difference on my LO3 when I put on the 1'' spacer. Is it snake oil? Not sure but I did notice a bit of a difference.

 

more power?...how did it act see i just want alittle more power....

 

My throttle response seemed a little quicker and it felt like it launched a little harder off the line. When cruising and trying to accelerate, it did make it feel like it was lagging a little bit more. Like I said, though, I have no numerical evidence and I think that I heard somewhere that people have done testing and found no numbers difference...

I just know what I felt. I would do it again, even if it doesn't really do anything

The one that I had was a 1'', no name brand I bought off of Ebay, and it had the swirls cut into the sides of the holes. I had it installed in about 20 mins. It came with the longer TB bolts (make sure you get those).

The only draw back to it was that the wing nut for the air cleaner and the top of the air cleaner housing was in the hood insulation, so an open element, a taller air cleaner, or flipping the lid on the stock air cleaner housing may not work with the stock hood... I know that the wing nut on top of mine actually punched a hole in my hood insulation, and was a mere few mms from scraping on the underside of the hood itself.

Good luck

i had a 1/2"-3/4" spacer from my nitrous kit which used a plate. once i put it on it made absolutely no difference on my car unless nitrous was put through it
