PI cams

Do PI cams fit directly into npi heads with no modifications? and do the PI cams make a npi sound more aggressive or just sound like a stock 99-04.

Also does anyone have some for sell for cheap..

RE: PI cams

you will need to change your valve springs. as for idle, it will sound stock.

RE: PI cams

The springs are exactly the same for all 96-04 Mustang 4.6s. They don't have to be changed unless yours are messed up.

You don't have to, but it would not be a bad idea
