Simple Performance Mods?

I just picked up a 92 4.0 AWD Aerostar. The engine seems to be in good shape.

Are there any bolt on performance mods for this engine? Intake or exhaust? I'm looking to replace the Exhaust System anyway.

Thanks for any help,
Steve

My setup with the Gibson exhaust and a free flowing intake with a homemade heat shield and a 180 degree stat has given me a very noticeable power and mileage increase. Headers, high-flow cat and a Diablo Delta chip are my next steps.

header source for 4.0?

What would be a good source for headers to fit my 4.0?

Do you know if anyone makes a system to fit the Aerostar?
