Customer Reviews

Love my A/C and breather bolts! Review by Robster
Just installed the 587 high flow breather and the black breather bolts on my 2020 iron 883. My first bike. Absolute, high quality stuff all around and what a difference! I could immediately hear the bike gulping up air from the first start. The stock one must have been suffocating the bike! I coupled the a/c with the vied instead of the expensive tuner to both save $ and my warranty. Still have stock pipes. After about an hour of riding this is a different bike! It seems the more I ride the more dialed in it gets and what a difference! From someone who rides almost daily I can tell you that the increase in performance is borderline drastic! It feels like a completely different bike now! The response, the torque increase, even the sound is deeper and more defined (with stock pipes) great, fantastic, awesome, products from DK customs! Why would you waste your time and $ anywhere else? Thank you DK! (Posted on 8/2/2021)
A well made product and good service Review by Acedoc
Ordered this after a lot of deliberation on the locally available air cleaners . The wrinkle black plate really looks “stock” and the Tri Gripper looks old skool on the cleaner. Opted for the external breather and while I was debating changing the moco setup it’s a no brainier once you see the gunk the stock filter is allowing inside - my stock filter was oil splotched and the breathers had a lot of oil and crud caked on.
I can thoroughly recommend the product and their service is top notch (Posted on 10/22/2020)
