The system ensures pressure equalization in the crankshaft housing and thus increased engine performance. The pressure in the crankshaft housing created by the burnt gases is sucked directly into the outlet via the SAS system (secondary air system). Depending on the engine characteristics, this results in up to 1.5 hp more power.
The collected oil mist is directed into a 2-chamber container in such a way that the accumulated oil can run back into the oil pan after the engine has been switched off.
Please note:
The set is not suitable for BMW Motorrad Motorsport Kit engines, as well as for vehicles with installed OEM activated carbon filter.
Certain racing regulations prohibit the use of crankcase ventilation kits.

The higher pressure cap stopped my overflow from becoming pressurized and blowing out. I did a combustion gas test on the cooing system and it passed all 3 times, so it made since the factory cap was to low of a rating for serve duty.
The internet provides many options. Not all are good. HHR provides top notch customer service and the best parts available.
quick shipper
awesome customer service
I ordered Avio fiber glass fairing and all necessary brackets for 2023 Yamaha r1. HHR answered all my questions by email and later by phone. The staff I communicated with were knowledgeable, straightforward, helpful, and non-judgmental. I've had been using the products for more than a year, and I have no complaints and am quite happy with it. I've heard it's easy to installl, too, but I had someone else do it, so I can't say if that's true. The bodywork has cutouts for the tail light and headlights. Works great.
