10-15HP is typical but the price is way out of line. Filters $80-90, tubes $65-80.

Agree with Fred. $450 is a total rip off! Go to www.roeracing.com He has the filters and smooth tubes...on sale right now I believe.
Agree with about 10 hp(i.e. ACR)...check out Roe Racing on this board...great prices, tube colors to MATCH your car).

I did a dyno run yesterday with stock inlet tubes and with smooth tubes. Very little difference in the low-to-mid-range, and maybe 3 hp at the top end. I didn't do a separate dyno with K&N filters only (I also had Borla exhaust and headers after my baseline run), but I would believe the combo of smooth tubes and K&Ns would provide 10 rwhp.
