I got mine from Advance Auto Parts, same thing. Works fine for a stock engine or engine with mimimal mods that doesn't turn a lot of RPMs on a frequent basis.
I just replaced mine on my very stock gt, got it from the dealer, about 35 bucks.
Couldnt afford the top dollar one, this will work for the year or so until I get new motor.
Im getting mines replaced very soon, I ordered the one from 50resto.com thats made by performance products for 80 bucks. I hear its really good. As soon as I get it (since its on back order) I'm slappin that thing on there.
Good Luck,
Jesse
I'm on my 3rd one from AutoZone. They are junk (only rated for 4,500 rpm). The only reason I got it from them again, is because it was under warranty. I'm getting a Romac or a Powerbond next month.
