Cummins intake products
 

I was searching around for something to help keep the trash out of the filter. I ran across the OptiAir filter first. It looks pretty well built and supports up to 1100 CFM...IIRC. Then I got to looking at more products. I saw the Magnum RS which closley resembles the 6637 filter. Now the thing I'm most interested in is the pre-filter which can support up to 1400 CFM, removing 98% of debris before it gets to the filter. Just wanted thought and opinions on the designs and logic of buying either of these?? I found Ryder fleet service web site that sold the pre-filter for $330.


Air Precleaner, AP8410, Fleetguard Cummins

Precleaners

OptiAir? Air Filtration

Magnum RS? Radial Seal Air Filtration

I've been looking at doing a ram air intake which would pick up a lot of debris...thats why I'm interested in the pre-filter.

Thanks for the input guys
