Our clean breather bolts feature an integrated and washable filter to keep any unnecessary particles out while maintaining the proper engine breathability.
Our unique design consist of a press in filter and snap ring that holds everything together from the back side of the bolt. The benefit of this feature is that you don't have to remove the pesky little snap ring from the front side of the bolt to remove your breather bolts and/ or carb support bracket.

These look great. I put them on my 88” S&S EVO. Had to run a 1/2” spacer on them since the thread depth of the head breather holes is shallower on the S&S than on the HD EVO heads. Still worked out great for me. I have over 1,000 miles with them so far. The oil weeping is minimal. I will run these agin if I build another EVO.

Crazy something as simple as a breather bolt can be produced at such a high quality. I always come back to Prism for all my bike needs.
