K&N E-3402 Air Filter Product Reviews

Friday, September 30, 2016 - Part E-3402
Just purchased a 1997 Kawasaki VN1500 Vulcan Classic with a very ill fitting air filter in a non-standard K&N housing. I had no idea what size filter I needed or part number. Phoned these guys up and spent about 40 minutes discussing the problem. They totally nailed what the problem was, advised me of the part number. I purchased the item on line. PERFECT! Thanks fellas, job well done.

The dimensions are exactly as described and of course it is the usual outstanding K&N quality product. Super fast shipping.

Installed on our Landscaping Tractor, increased power significantly and decreased fuel consumption by 40.
