Getting the right External Breather Systems (EBS) for Your Bike

Choosing the Right

External Breather System (EBS)

For Your Bike

 

"It seems totally ludicrous to me that nobody really offered an external breather intake that was a complete system.

I've been doing high performance cars for years and would never even think of rerouting breathers back into the intake tract, always vented them to a can or to atmosphere. SO glad I found your products." -C.H.

3 External Breather System Exceptions:

 

The below aftermarket air cleaners (that do not vent externally) use the stock style breather bolts but there is no access to those bolts.

Simply drill access holes to install the external breather hose onto the heads of the bolts.

You can see the systems to use HERE

It will attach and look like this: 

 

 

 

 

There are also Air Cleaners that look like the Arlen Ness inverted, that use nipple head bolts,

but the filter, or a metal plate, blocks access to those bolts.

 

To vent this style air cleaner externally, you will need to weld or plug the head of the bolts,

then drill a vent hole in the shaft of the bolts and tap into the pass-thru spacer.

This style air cleaner also uses the stock breather bolts but there is no way to access the bolts as they are covered and the standoffs (that bolt to the heads) are not long enough for the barbs of the DIY External Breather System to fit.
