[Rich-Tripower]

I've been reading up on air filters. We currently have reproduction foam air cleaners on the tri-power. These foam air cleaners don't get a very high rating for stopping dirt. I re-oil them every Spring. We've only put about 500 miles on the car in the past 4-5 years so they aren't getting dirty. But, if the foams aren't all that efficient, I could get paper filters and save the foams for car shows or whatnot.
