I got mine from Fred Beans Chevy they are forum vendors i think it was around $50 not sure though check there link on the left, and i guess if it's good enuff for the 400HP Z06 it should be fine for a stock LS-1.

Hi bradleyls103 -
You might notice it by SOTP - my guess is no, you will not notice the increase but you might get some placebo effect. It is very difficult to notice a few hp gain without some specific way of measuring.
JMHO.
Have you heard of the zip-tie mod? Search for that - no $ (except for the zip ties) and it will open the airbox up as much as it possibly can be opened.
best regards -

You might get a little boost from it. I had one on mine for a while until I bought my Blackwing.

I put the Z06 cover and K&N filter on my 04 with A4 and 2.73 gears. There is a definite SOTP difference. It is now very easy to spin the tires from a stop. The car is also a bit louder and seems to respond quicker. I am very happy with it.

Yes, I failed to mention that I have a K&N filter and the all important hood seal.
