Paper air filters

Kinser

No, Kinser makes a 14 inch filter for traditional 4 barrel carbs. I have been running one for a couple of years. I haven't had any issues. I clean it every race and have never found dirt in the carb. Motor HP seems good or better than the paper Wix filters I was running. I was just curious if anyone else had tried them.

Used to be the only thing I ran on the sprint car and had a noticeable difference between it and a k&n air box. Makes me think I should get one again

For what it's worth - I will never run a R2C again.

I ran only throwaway paper Wix filters for years, then won a free R2C. Tried it for a season. During the offseason freshen, my engine builder said to never run whatever air filter I had been using because there was sludge in the engine. Switched back to paper and never had another problem.

On a similar topic - do Outerwears pre-filters really work? My brain says that if I'm filtering out dust with a super fine pre-filter, whatever dirt gets through to the actual air filter will pass right through since the air filter is more coarse than the pre-filter. Is this correct?

Interesting thought on the Outerwears. You may have something but I use 'em on the carb and oil breathers. A few shots of Oil Eater and a water rinse every week keep them clean. We run a few heavy tracks and, at least, they keep the big chunks of dirt out and my Wix paper filters last longer and my carbs seem to stay cleaner. Someone on another thread a while back said they kill air flow to the carb and he didn't like them but my carbs are jetted a little smaller than many of our friends and they don't run lean so I doubt that.
