If you can find a good deal for like $20 or less then get it.
But don't go to Kragen and buy their $50 rolls. That's a rip off.
You can find some online for around $15-$25.
If your hood always gets hot and is starting to fade, sure get it. Or if your header always gets extremely hot.
thnx that helps..I dunno about more power....
In my opinion, it's like changing spark plugs or something along those lines.
They might not make that much power, but it's something that will make your car run better.
It's like a "supporting mod" if you want to call it that. It's not a major modification itself, but if you get it, it's one of those things that will help it run it's best.
