The best filter out there is the Purolator (PureONE) part#PL14610. It's the same filter that's on the ZX12, ZX10, ZX636 etc. We spent long many hours debating this on the 12R boards & done tons of research and comparisons to find the BEST of the best filter. This filter strains out the smallest particles and has a Anti Drainback check valve, and more pleats for greater surface area.
Not saying that the OE filter is junk, but it's made by a company that's NOT anywhere near the top of the list for the highest quality filters. It meets the factory specs and that's great, but there are much better filters out there.
Also I'll say this a larger better flowing filter will give you free HP. It's worth 6 to 9 HP on a 500" PS motor. This is because the pump don't have to work against the restriction of the small filter thus allowing the motor to spin more fleely. = Free power
So just think about how much a stopped up dirty filter cost you.
OH! and best of all the PureONE is about 6 bucks compared to the Stealership model being 12 or so.
