Mass Air 5.0L in 78 Fairmont

[TWR2003]

Can anyone give some input on using 'Mustang' EFI 5.0L cold air kits on a 1978 Fairmont with a 5.0L mass air EFI install? Like all early Foxes my Fairmont has the large round hole in the passenger side inner fender where the stock air intake tube was located. I know on the later EFI Mustang the air intake/filter box was located further forward on the inner fender (where the battery was on the early Fox) and the cold air kits are made to fit the large oval hole where the Mustang's filter box was. Are there any kits out there that would alllow me to use the existing F/Z round air intake hole or do I need to cut a hole further forward. Or can any of the Mustang kits be modified so I could use the stock round hole? I am relocating the battery to the drivers side so I have that space open on the passenger side now. Or should I just let the cone filter sit inside the engine compartment (no cold air)?

Thanks

I just used a cone filter as it was more trouble than it was worth to devote any amount of time to it....I was lazy when it came to that...lol

I don't see why you couldn't modify a mustang kit to exit through the existing hole.

I save the Air filter housing hole from an '86 Mustang so I can stuff it in Friggin' Futura.

I hope to tack weld it in...

You can use a cone filter in the engine compartment, or aftermarket companies like AFM (https://www.andersonfordmotorsport.com/) have kits that go through the small hole just in front of the strut tower, but they're not cheap.

The previous owner of my car cut a hole in the inner fender for a normal Mustang cold air intake. If it was my choice I wouldn't have done it.

I did this on my ltd lx, just another option: get a couple 90 degree rubber tubes- one for tb to maf, and one for maf to the existing plastic tube going through the fender, and then I just clamped a k&n round filter to the bottom of the tube inside the fender. Cheap cold air.
