K&N YA-6598 Air Filter Product Reviews

Nearly 30 years ago, I was using a K&N air filter on my MK2 Ford Escort after I dropped in a 1.6 litres engine with high lift cam and Piko exhaust system. The K&N air filter was the icing on the cake. This time, fast forward into the future. I wanted to replace the standard OEM filter in my Yamaha Dragster 650cc Classic with a well known performing brand and there was only one option - K&N air filter. Slotted it in very easily, instant difference and the bike sounds even better too. Thanks, K&N.

I have coupled K&N air filters with Pulstar plugs in all my cars and motorcycle. Makes considerable differance in performance and fuel economy. I tell everyone I can that these are the best air filters you can buy. I might add that I also use K&N oil filters in all my vehicles also.

I like my new filter a lot. My big test for this product was going up a hill. Before I got the K&N filter I would start the hill at 80 MPH and at the top my speed would be 60 MPH. With the K&N filter it stayed at a constant 77 MPH all the way up. My bike is a 650 Yamaha v-star.

Filter fit just fine in stock cover. I noticed a performance boost in the low rpm and about 3-5 mpg improvement.

Replacing my stock air filter with this one seems to give me more power.
