Milwaukee-Eight Screamin’ Eagle Air Cleaner
As you know, 2017 brought a new engine to the Harley-Davidson Touring lineup, the Milwaukee-Eight. The singlecam, four-valve-per-head engine is a beautifully designed platform that makes us forget about the beloved Twin Cam engine, which we adored. Changing up from its past releases, Harley-Davidson released its engine upgrade kits, stages one through three, at the same time as the bike, making it immediately upgradable. Then in January, stage four was released.
We decided to install a Stage 1 kit on our borrowed 2017 Road King. Still waiting for the mufflers to arrive, we decided to go ahead and slap on the air cleaner. We went with the Screamin’ Eagle Heavy Breather Performance Air Cleaner (part #29400263, $399.95). The look of the stubby filter in the heavy-breather platform is really rad and flows well with the rest of the bike. Installing a new air cleaner is one of the easier performance upgrades possible to do yourself with only a few simple tools. Follow along with us as we help this ’17 FLHR breathe better with a Screamin’ Eagle Heavy Breather Air Cleaner upgrade.
Our shiny, new Heavy Breather Air Cleaner ready to help our Milwaukee-Eight breathe deeper!
This was our starting point for this install, with the stock air cleaner removed. We started off by installing the new gasket onto the throttle-body face.
With the gasket in place on the throttle body, we attached the back plate to the cover assembly using the three supplied self-tapping screws.
With the cover assembly attached to the back plate we went ahead and started the two breather bolts by hand securing the assembly to the engine. (Do not tighten the breather bolts down all the way at this time.)
With the two breather bolts started by hand, we then installed the three bolts to secure the back plate to the throttle body. Once the three bolts were tightened down, we went ahead and tightened down the two breather bolts completely.
With the back plate completely tightened down to the heads and the throttle body, we then installed the bend and filter element to the back plate assembly using the supplied three bolts. Once the bend was tightened all the way down to the back plate, we tightened the air filter worm clamp to the bend.
And with only a few basic steps we had our new Screamin’ Eagle Heavy Breather Air Cleaner on our Road King ready to pull in more air.
