Customer Reviews

Great breather? Review by John C
Ordered this along with their premium catch can external breathing system. I've been a customer of theirs for about 10 years now and they always offer quality products at a very reasonable price.

I watched a lot of their YouTube videos and went with the 606 for the most airflow from a non-oval breather (I don't like the look). Kit comes with good instructions and it didn't take long to install. My 2021 Sport Glide breathes so much better now! (Posted on 7/31/2023)
5 spoke 606 with vent kit, Review by Steve
Directions for the 5 spoke cap hard to read mixed language, the end bolt that hold cap on has plastic fastener….. not good, the vents have scratches all over aluminum? Watched install Video and his seam to be a nice polished look, not impressed with quality for price and pour directions (Posted on 7/1/2021)
