Cobalt f/l header into 04 sunfire
Tuesday, March 08, 2022 2:40 PM
New guy here. Picked up an 04 sunfire 5 spd. Looking for 25/30 more HP.. have a 2.4 big runner intake here, and and done some ex work.

Cant seem to get a Pacesetter Header anymore ever place ive talked to saysback ordered. So there is a Cobalt full length header new never put on, near me its really cheap.

Ive read some will fit some will fit with a hammer, nope they dont fit.

What all is involved, or rather what doesnt clear?

Not new to cars..just these. Have had soem 11 sec GNS, and recently 11 sec 2.3L FOrd OHC turbo stuff [SVO and a cougar] and ive been porting cyl heads for 15 years full time. Appreciate any first hand info anyone has as t what they ran into if trying to use a cobalt header.. they look similar enough.
