Who all makes headers for the 4.2L V-6, I know Gibson does and that about it. Or I'm thinking about a fan kit form Troyer. I would like to know if the fans or headers would be the best power gain?

 

I would get fans. Better A/c, engine warms up faster, adds 15-20 hp, makes engine noice quieter. Plus, I dont think headers are going to sound too good a on 6 cylinder...

order from here for a better price on the fans! www.Jusnesmodified.com

 

I dont care about sound I want more power.

 

If your looking for more power I'd go with the fans.

 

headers will reduce more low end torque and move it to the 3-4 thousand RPM range. Plus they will put a bigger dent in yo pocket!

 

Fans, headers won't get ya much for the ol 4.2, the 3.8 mustang had headers stock and didn't do much for them.
