This is a Christmas gift so it has not yet been installed. My ordering experience was simple and efficient and I do not see that there will be any problems with your well proven product.

The online store was easy shopping for great K&N products, the Billet oil filter was a perfect addition to my Harley

I bought this for my 2000 H-D FXD. Easy to assemble, install and looks great. Gave it 4 stars for the following reasons: A little pricey (would've been nice to at least include a couple K&N stickers for the money) but, worth it in the long run. Somewhat cautious about the filter element not twist-locking into place on the adapter ring. However, the Viton seals and crankcase vacuum should keep it together. No leaks so far. We'll see what the season brings.

SS-171 is a very well, engineering designed device, that certainly improve engine performance on Harley Davidson motorcycle.

VERY NICE finish and overall quality. There are other pretenders out there with CRAP they want to sell at a discount BUT this unit is the REAL DEAL. Like anything else, you get what you PAY for. Bike runs COOLER with this Hi Flow Filter. Have been a K&N fan for a VERY LONG time.

This filter did what it was made to do. Easy install. I'm glad I made the investment. It dropped the bikes temperature by 25 degrees.

I am very pleased with the look, the fit, the finish of this filter and based on all my previous K&N products I am sure I will be happy with the performance of the filter.
