    Love the product and amazon was good with sending me a new one when it was missing a part it’s a spacer washer for soft tails ( part o) so they send the new one and it’s also missing the part so they gave me a parcial refund and let me keep one of the products over all it was a real pain in the ass cuz I had to bring it to Harley cuz the spacers weren’t even in the instructions but they were in the instructions online anyways Harley charged me 179$ to put 4 washers wear the spacers would go I called k&n and they sent me spacers oh and I brought it to Harley cuz with out the spacers it crated a gap so air could go straight in and if was idling at 5000rpm bypassing the sensorsBut it’s all fixed and I love it

    A nice “adornment” to my bike…but more importantly, better breathability!

    Awesome addition to complement my 2:1 D&D exhaust. Easy to install as well. I chose this set up because it will protect my filter from rain better than the other ones.

    Like it allot. However large throttle body o-ring was to large in circumference, and would not fit/stay in o-ring groove. Had to modify and reglue correct size. As i already had stock filter system removed and did not want to reassemble only to remove again to replace when a new/correct o-ring could be aquired

    Liked the air scoop / blower design of the cover. I have recieved many compliments on how great it looks! and I try not to buy int the “added” HP features many manufacturers promote, but I do believe I see increased performance by the “velocity stack” built in to the mount.

    It looks good it’s nice installation was not 100% correct didn’t have to use the spacers also there we’re blemishes on the top of the filter case which I’m not too happy about considering this was $250 other than that seems pretty good so far

    Really opened up the bikes intake. She breathes much better. So much so that I had to have it dyno tuned because I was dumping fuel out of the intake breathers. So much better than stock!
