I was talking with someone involved in building a Baja project vehicle, and he was talking about their plan to use UNI air filters.

Well, I'm curious, so I go surfing and find http://www.unifilter.com/

The UNI filters are oiled foam (like Amsoil)- NOT oiled gauze (like K&N, AFE, etc.)

These filters are VERy popular for motocross, ATVs, and other off-roaders and have a reputation for great filtration among the Baja racers.

I would imagine that an oiled foam might not flow QUITE as much as the oiled gauze, but the filtration seems to be a much higher quality.

They list a drop-in for the CTD on their website. But they also list a universal cone filter with various IDs available.

What's the ID of the stock air snorkel? I wonder if one of these couldn't be made to work.

BTW- they're WAY WAY cheaper than an AFE or similar- these go for around $50.

Ok, I'm curious. I wonder how much less these flow? The inlet for the stock air box is 4" - I can't remember if that's OD or ID. You think the smaller flow is why they're so cheap? Wanna run some tests?

I am working on getting into one-- I like oiled foam over oiled gauze. To me, it would be worth it for even a mild improvement.

Like I said, they are highly respected. Guess which air filter's going on the T-rex race truck and the Baja Bomber? Hint: it's not an AFE

I think the one you'd need for a closer to stock application is UAP-908. It fits on 4" pipe. It's 6 1/2" round at the bottom, 5 1/4" round at the top and 11" inches long. Too bad they don't sell one that fits on 5" inlets or I'd think about trying one.
