Weber Air Filters

[crazycasey]

Hey gang,

I’m setting up some 48 IDA’s for a 289 in a Mustang, that will eventually make it’s way into a 289 FIA car. The Mustang has little more room for an air cleaner than I would assume the Cobra would have, so the discussion may be relevant.

What are you all running for air cleaners? Most of the photos I see have either the screen that pops into the velocity stack (sold by Redline), or the mesh screen that pops over the velocity stack (black band around the bottom). Based on my rudimentary measurements, I don’t think I have room for something like a K&N (even the shortest one). I’ve seen a few people running the foam disc type filters, though I’ve heard they’re terribly restrictive. I’ve seen no one running UNI filters, which surprises me because they actually work pretty good on motorbikes. Is there anything that I’m missing?

What would also be great, is if folks would post what effect whatever type of filter they ended up going with had on their jetting.

Thanks for reading!

Casey
