Great Product Review by Jocko
Be sure to clean threads both in the head and the bolts. EZ install, no drip, no spit, look great. (Posted on 11/3/2023)

Perfect Review by melville74
I didn't want anything going back into my engine. DK's excellent videos helped me make the decision for my setup. Easy to install, happy with them! (Posted on 10/6/2023)

Simple solution, works great Review by Black Bart
I have two sets, one aluminum and one black one on my 2020 FXST and one on my 2022 FXBBS. Easy install solves the breather issue on my M8's. Great product. (Posted on 9/28/2023)

Piece of mind on my M8 Review by NK Bobcat
I installed these on my 2019 Tri Glide. I used a few layers of Teflon plumbers' tape, and they fix my M8 114 well. I have a full stage 1 setup and so far not a single drop of oil has emitted from them. I know it shows in the description and in their videos that they work fine on the M8 as well as the Twin Cam, but they should change the title to reflect that. (Posted on 4/30/2023)

Polished Aluminum breather bolts, WOW Review by Grey_Bush
So what can one say they are functional and pretty to look at. What more can one ask for. Running this on my 2016 HD Triglide with a 103ci. I did add the spare sponge just to be safe. Besides if its in the breather I cant loose it. (Posted on 4/24/2023)

Fantastic Review by jimijoe
I opted for this style of crank vent because I don't have any carryover issues and didn't want any unsightly hoses hanging off of the engine, so yours fit the bill exactly and are a GREAT product! (Posted on 11/10/2022)

Works as advertised. Better options available. Review by Joe Z
These were easy to install. They do as advertised, but you will get oil on your bike. (Posted on 4/25/2022)

Looks good and works great! Review by Gary
This is a quality made part and an inexpensive alternative to hoses and collection containers some crankcase engine breathers use. I’ve had no issues of excess oil on the engine. Oil vapor seems to be drawn away as air circulates around engine & actually seems cleaner than oil collecting in the intake breather/throttle body or a collection container. This may not be the case for all, but works great for me. Easy to install, looks good and work well. Very happy! (Posted on 8/4/2021)
