Have a warning for those installing this piece. It requires removal of the Heavy Breather down to the Backplate. If you have one of the older heavy breathers, the adapter ring is a
soft rubber ring which accommodates the 58mm breather tube to the stock 50mm intake. See here:
SE Heavy Breather Instructions, page four, part #29395-08A. This ring has now been retro-designed by HD and is now ballistic plastic so that is will not collapse and get sucked into your intake butterfly under full throttle like mine did.
On the new kits, its glued to the intake tube and can't come off. It's probably worth the time to replace the old part as mine could have gone farther into the engine and caused damage. Luckily, my motor died and the fault codes all pointed to an issue with the throttle body so I was only down for 1/2 day. Still had to get towed to a dealer on my way to Coulterville to meet up with JC, Terrie and some of the Nor. Cal crew.
