i have a 87 grand marquis and i was wondering if someone could tell me what headers and what cold air intake would fit on it.? thanks

 

only guessing you are talking about a cold air setup kinda like what is in my signature picture? i have done this to a few other Grand Marquis and Grand Marquis cars... headers mounted to the car wont help much unless you swap the cylinder heads and cam... but to do that you have to get a computer from a Mark 7 with HO and change firing order along with a few other things to make your engine into a HO engine pretty much...
