Purchased the set (155-157) for an older KTM. Great price and fast delivery. Confident in product quality.

KN-157 is a quality filter. Sadly I was unable to find the short oil filter required for my 2015 KTM 690 Duke on K&N's web site and guessed wrong that this one would fit. The KN-157 is the correct length and diameter but lacks openings required at both ends for the 2015 KTM LC4 engine. For now, I will have to go back to KTM for at least the short oil filter.

Fact: K&N filters are quality products. Have used these products for years without issue. Quality beyond question. Fact: Filters were on my doorstep 26 hrs. after the order was placed. Fact: It just doesn't get any faster than that.
