Excellent service, Fast Shipping, Went on my 1956 Porsche 356A, Solex P4011 and fit great.

Replaced the OEM's in my 11' Porsche GTS - like a nice big breath of fresh air.... literally. Much happier, both of us.

This is the 5th K&N filter that I have installed on my vehicles. They are high quality and fit perfectly. My Porsche filter finally failed after 20 years. I just sent them a picture and a new filter showed up in several days. Great customer service!
