K&N 33-2573 Air Filter Product Reviews

Wednesday, December 31, 2014 - Part 33-2573
My 1989 BMW needed a new air filter and the lube company did not have one in stock. I ordered the air filter on-line and I had it in my possession almost immediately. My husband put the air filter in the car for me. My BMW is keeping up with our Audis now. This is a new type of filter for our BMW so I put the K&N info in the glove compartment, as they suggested. My experience with K&N and their product is good, hence the 5 stars.
