Hello, I have a Grand Marquis 2004 Ultimate Edition


and I want improve the car performance.


is that possiable for the car?

 

Yes. there are cold air intakes available as well as exhaust kits (welding, cutting, and bending may be required). Serious performance mods will require fabrication and/or modification to make fit. You can use some things that bolt-on for a mustang gt.

do a google search for the part you want with your year and model and you should find some stuff. But like I said, serious mods will require fabrication and modification of the car.

 

I don''t need the serious mods.


I justwant the cold air intake and the exhaust kit.





Do you were I can find them?

Google for starters.

search for [ 2004 "grand marquis" "cold air intake" ]

then click on Shopping at the top.

you can also use something like a K&N Apollo universal kit.

The best bet for an exhaust is to find a same year dual exhaust setup, like that on a police car (if yours doesn''t already have that), or a muffler shop that can install a performance setup since any exhaust kit will be a universal and require cutting and welding.
