Hey Steve,
I can appreciate that there is a lot of misinformation on the net regarding re-usable air filters. I used K&N filters for many years in off road racing and appreciated the ability to clean it between races. I chose not to use one in my Porsche because of the sensitive MAF in our cars and this ISO 5011 study on intake air filtration. YMMV
K&N air filter or OEM, why OEM is better
