IMO >I think they are totally worth it. as much as the BAHF costs, if I can block the large particles first before they get into and clog the pleated filter and then rely on the pleated filter to catch the small stuff I personally think it will more than double the life of the BAHF. We have run them on air filters and oil breather filters on the dirt track cars forever specifically for that reason.

They are both dry filters, do not require oiling. I wont bother you with details, just do some searches on this forum or google about them. Less filter area than a BHAF, but flow better, and still filter well.

the pre filter really cuts the flow down on the air filter. I would not run it if you want it to breath...
