In the picture below you can see the stand-offs that are part of the backplate (that butt up against the heads). This system includes hose barbs that can be threaded into those stand-offs and allow you to vent externally, as discretely as you would like.
This Picture is showing an Ness Big Sucker Air Cleaner that has our Sano Black Air Cleaner Cover, specifically made for Big Suckers & HD Stage I Air Cleaners. You can see this cover HERE.
An external Breather Kit is preferred with any Air Cleaner System. This allows for only clean cool air to go into the air cleaner and engine, increasing performance and engine longevity.
This DIY kit is designed for aftermarket Stage 1 Air Cleaners that don't allow for venting out the end of the breather bolt. It can even be used with the stock air cleaner.
The EPA has required Harley to route hot, dirty, oily crankcase air back into the air cleaner compromising the performance of your engine. This vents it without compromising the performance and longevity of your motor.
With this breather system you will experience a slight performance increase. This is because engines like Cold Dry air!
Fits All Twin Cam & Milwaukee-Eight Models - 2000-Up Touring & Softail, 1999-Up Dyna
Fits All Sportsters & Big Twin Evo Models - 1991 & Up
*This kit requires drilling (11/32" drill bit) and tapping (1/8" NPT Tap) threads into the stand-offs (that are part of the backplate). The benefits are that you can completely hide the hoses, if you wish, and it will work with air cleaners where no other external venting system will work.
Drill bit & Tap kit is an option above.
If your air cleaner system will accept the Stock OEM breather bolts, we have other breather kits that are straight bolt on, not requiring any drilling or tapping. You can see the one for the Sportster HERE, and the one for the Twin Cams HERE.
Filter may, or may not, have a small loop in it. This does not affect the aesthetics or installation choices.
