What Air cleaner is everyone using with the PF4,I'm trying to get some ideas I have the 35930. I've tried a K&N 66-3040 but it was a no go. TIA

This kit is my next big plan for my bronco, I hate the look of the foxbody efi.

You have tons of options for style air cleaner. Something chrome?

Stock air cleaner for starters if you still have yours. You lose some flow especially at higher rpm but at least don't usually have to worry as often about fit with those.

In addition to oval shaped ones, there are larger triangle ones that should work decently.
Just be sure to use the paper type and not the old foam-filled ones!

Lots of options.
If you want the hot air open element traditional hot rod look, an offset base like https://www.summitracing.com/parts/knn-85-3540 will help clear the distributor.
Other options exist as well. My F250 I sold last month on BaT had a enclosed air cleaner with a snorkel that had a large recess to clear the distributor. '77 with a 460. I hot rodded it a little and put a second snorkel on the air cleaner and both went to the core support for a cold air intake.
The Sunbeam Tiger had a space limited air filter that should work as well, probably find one as a repop.
There are blow through supercharger hats that will convert that flange into a tubing that can be routed for a cold air intake, they are high flow as well.

The low profile triangle one I would NOT recommend is something like the Edelbrock ProFlow. Some wire mesh and a very open cell foam. Useful in regards to keeping rocks, boulders, and small children from falling in. Useless for actually filtering.

It's not the issue with the Proflo 4. It's the Duraspark sized distributor that comes with the kit.
I ran into the same thing a regular Edelbrock 4 barrel carb. The distributor cap, throttle linkage, and fuel inlet were in the way.
I found that the large Edelbrock triangle air cleaner would clear all those things if you put it on backwards.
I'm building a 347 with the Proflo 4 for my '62 Ranchero project. I plan to get another Edelbrock triangle for that too.

Spectre air cleaner, not cheap, works great. I have one, but I also have a quadrajet and needed a 1/4 ring below the air cleaner to clear the quads accel linkage. Not an issue with yours. You can return to summit if you don't like it.

I've acually been looking at the Spectre as an option.

Thanks , I'll take a look at the Triangle one.

Lol, Thanks

I may end up going the stock route.

Thanks, I'll check them out

You could try an oval shaped one and turn it 90 deg. just asking you already considered/addressed potential hood clearence issues??

I have, I'm also going with a 1" body lift to help with clearance for the air cleaner & 4R70W

This kit is my next big plan for my bronco, I hate the look of the foxbody efi.

Yes, they are somewhat bulky.

Don’t know but the motor looks pretty sweet

Thanks, I really like the Explorer Serpentine setup.

Did we find a solution? I'm following this and also looking for those running the Pro-Flo if it fit under the hood? 302 with a 1" body lift.

Thanks

If you look for a blow through carb hat there is a lot of options. I ended up with a procharger low profile (2") hat with my 408.

Just curious if you ever installed that and how it fit? Any pics? I wonder if it will work with a 351?
I've installed it as pictured above and the body shop has set body on with hood so I think it's good to go, sorry I don't have any pic's of it with body on. Hoping to get it back painted in November

I bought the spectre and a 1 inch body lift but the pf4 still sits too high on my 351 to clear the hood by about an inch.
