Upgrade your engine bay with these custom AN10 valve cover fittings, 3D printed from durable PETG for heat resistance, strength, and a clean finish. Designed to fit directly into the stock valve cover ports, they make routing your PCV or breather lines to a catch can easy and tidy.
Made in small batches right here in the shop, these fittings aren’t mass-produced — they’re crafted for enthusiasts who care about fit, function, and reliability under the hood.
This item is still in its testing phase, and will be available soon! I want to make sure this part holds up to the standards that I expect it to.
