Misc. Air Filter Question

[Lou Tenant]

What air filter are you running on your 79 with the AMC 258 i6 / 4.2l and power brakes? The original air cleaner is long gone and it was replaced with a, K&N. Which doesn't fit the new 2 barrel carb.
I've read a cold air intake system is needed, but I cant find one.

The original factory ate hard to find in rough shape and crazy expensive.

Thanks ,
Lou

I wouldn't say cold air intake is needed. You lose maybe 1-2 HP without it. I run an open air cleaner on my 83.

K&N makes both a 7" and 9" filter housing that fit with a power brake booster.

I should also mention I'm planning on doing a single barrel carb to,a two barrel if I can find an intake manifold. My plan is to do a complete new fuel system from the tank forward.

I have a Howell TBI on mine so it's likely a different base than the 1bbl.

If you go with a motorcraft 2100 for your 2bbl or one like it, your options open up since that base is shared with most 4bbl carburetors. That's what my TBI uses.

Like Grimjeeper stated, if your new 2 bbl carb is the common 5-1/8” diameter, there are a ton of options out there.

I have a Howell too and the 10” Edelbrock 1208 fits if shoe-horned against the booster. This is the biggest one I could fit in that space.
