Sprint P08-F85 Long term
I am doing my winter servicing on the H2. And I purposely left the Sprint P08-F85 filter go for 5000 miles in the dirtiest, nastiest, dustiest, place you could imagine....Reno, NV. We have construction trucks lined up on our freeways. It is a dustbowl of sand, silt, talc, dustdevils, blowing sand and more dust, everything. Like everyone else I worry about what gets through a filter. Most use the Sprint P08, I took a chance and got the P08-F85 which flows about 4 times the air and is waterproof. So here are the results of this long term test (the bike has 23,000 on it and the filter has 19,000). As you can see the filter is just nasty, really nasty. BUT the clean side is spotless , not a trace of detectable dirt. One picture shows the crumpled towel which I just took a swipe off the outside filter carrier, the towel has nothing more than the oily residue that is the color of the oil. Nothing on the inside. I have been riding bikes for 50 years, I was a professional motorcycle mechanic for a 15, I have logged hundreds of thousands of miles on my bikes. And this just astounds me as to how clean it is on the inside. I do attribute some of the cleanliness to the oil film that gets spit up into the filter, which is just fine with me. All I can say is WOW.
