K&N quality and performance! GREAT!

March 27, 2011

I have been a dedicated K&N customer since at least 1996, and this product does not disappoint! You get an awesome quality product here, and the reason I bought this was it uses your stock air cleaner cover for a factory look but pulls in MUCH more air. The assembly directions could be a little more clear in the correct location/orientation of the "Spacer" nuts, just make sue you read carefully. Also Do NOT forget to put some BLUE thread-locker on the air cleaner cover bolt (I didn't do this and after about 280 miles it vibrated loose and I ALMOST lost my air cleaner cover).

I would recommend this item to a friend.

Nice Product

June 18, 2010

I went back and forth between this product and the Big Sucker. Decided to go with the K&N because of the company's history for making a quality product. Install was fast and very easy, instructions were detailed and veru idiot proof. Performance increase is significant. Installed this with a set of Vance and Hines Big Shots and a V & H FuekPak. Runs very nice.

I would recommend this item to a friend.

SIMPLE INSTALL /BEST K&N ASSY YET!

April 6, 2010

First off got quite a deal through Dennis Kirk using there price match on top of that there shipping time was outstanding (as usuall) Back to the K&N 3930, install was a breeze, about 1/2 hour but it probably would of been less if I had not to dig up the tools. I feel that there 3930 is a vast improvement over the earlier HD style Stage 1 air cleaner kits using the round filtyer. This by far is the simplest to install.

I would recommend this item to a friend.
