Customer Feedback


I read in a few forums that some folks have had fitment issues with this product. I installed this on a base model 2012 Triumph Bonneville, and it seemed to have fit fine, although I can only speak for this trim specifically. So far the filter seems to be working okay, but I have a hard time feeling a noticeable difference in power, but I don't go to WOT too often where a change like an air filter would be most noticeable. Since my company's only motorcycle dynamometer is in 130 rusting pieces in a parking lot, if anyone out there has any dyno results with both the [brand] and the stock air filter, I would love to see them. As far as dealing with K&N goes - I am perfectly happy. The product did what it said it would do, it shipped on time, and arrived in the mail quickly.

The k&n air filter added 6 miles to the gallon on my 2008 land rover. I have used the air filters in my last 6 vehicles. I am very pleased with this product.
