Replace Your Plastic Head Breathers with Feuling's Billet Aluminum Head Breathers

Okay, everybody! I'm here with Harry from Fueling, and I've got another— and I'm serious—no-brainer performance upgrade. Everybody has this problem. There's not a bike out there that doesn't breathe hard. These big engines run hard, they're fast, and they all have blow-by.

Harley-Davidson has these plastic breathers. They're—well, for lack of better words—garbage. They have a single O-ring, they don't seal very well, they crack, they're non-serviceable, and they let all the oil go right past them. Where does that oil go? It comes out of your throttle body, drips all over your cam cover, and makes your air cleaner filthy. It's not great.

So, what do we have here?

Yeah, so we've designed a billet unit that has a serviceable umbrella valve inside—uh, from the Twin Cam engine—as well as a filter element inside and a separator disc. We also have some very large drainage holes on the bottom to prevent any kind of oil buildup.

These guys work well on stock to wild engines—anything that's having some blow-by issues—or you can use it for preventative maintenance.

Yeah, even if you don't have any blow-by issues, you're going to.

Yep, okay, and you really gotta do it, because what these do is separate the oil from the air mist. So, the oil stays inside your motor, and the air mist comes out. You don't get that oily mess all over your motor, and it doesn't mess up your air filter.

It's easy to install. If you're not doing a performance build at the time, all you do is pop the back of your gas tank up a little bit, and they go right in.

And I gotta tell you—if you don't put them in, you're missing out. It's a big mistake.

They're available at Lifestyle Cycles and on the Lifestyle Cycles online mega store.
