is this bogus?

[99GP/GT]

I used to own a 99 Camaro SS that recently got totalled so i picked up a 99 Grand Prix GT 2dr for a great price and was looking on ebay for some mods for it and ran across some resistors saying 20+ hp gains. Anyone know if its true or bogus?? :dontknow:

it's a lie, i bought one for my TA when i first got it. figured heck, why not? but there was no real difference in power.

Not that I've looked, but let me guess, it'll lie to the computer about the intake air temp right? I think you can get like five for about $.75 at Radio Shack. Not that I'd do that particular mod...

Just go to Home Depot and make your own Cold Air Induction

Go to
http://www.zzperformance.com/grand_prix/, http://www.pfyc.com/c/GP/, http://www.intense-racing.com/, or go to www.ClubGP.com (http://www.ClubGP.com) for mod suppliers.

You could probably pick up a couple used perf parts in the parts for sale section.
