It looks like the K&N does filter better than the "97.5%" efficient Purolator Classic. 97.5% is a good rating anyway, so I am pleased with the results, as I pay a lot more for the K&N. As far as fill-time flow, the K&N was about 20%-30% faster for me. Left K&N HP2009, Right Purolator L20195. Bosch Premium.
