I am currently running my conical air filter off my mass air meter as shown in my sig. pic. I have read several posts on here that that is not the best place to have it because of underhood heat being drawn in and air turbulance affecting the air meter. So that has got me to thinking I should go something different.

My question is what would be better, the stock air box with a K & N filter or a cold air kit with the filter in the fenderwell as another option?

My concern is going to a different setup I would have to have my Pro M Air meter sent back in for another $100 re-cal, as it is calibrated right now for the filter attached to the meter. The only other option I would have would be to go back to the C & L air meter, that I also have, and I do have the brown sample tube for it to calibrate it for a "cold air" set up. Although the C&L meter does not seen to be a Stangnet favorite, but I really have not had a problem in the past using it.

I have C&L's on all three of my Mustangs and have never had a problem. One has a cold air kit, the other two have stock air boxes with K&N filters. Po-tay-to, po-taht-to. Pick which ever one you like and go with it. Personally, looking at your photo, I'd go with the cold air kit. That's a pretty sweet engine bay.

FWIW there was absolutely no difference in on-track performance on my car between either of these two setups, but the performance was a lot better than when I had the filter in the engine bay like you have it now.

A curve before the MAF would be the cold air kit, correct?

Where would one find a stock OEM airbox and piping for a Foxbody?

Ebay fairly regularly for cheap. Junkyard. Craigslist. Stangnet classifieds.

the normal fender mounted style... you can run a set up like mine with an open filter and a heat shield and do just about the same thing.

anderson power pipe is fender mounted and has the maf on filter.


found this issue when i was working mostly with 03/04 cobra's about 90% of the time the curve before the MAF would cause the maf counts at idle to go crazy...the air was swirling so to speak.
