KIMISS 13mm Car Air Filter Crankcase Filter Crankcase Air Filter Crankcase Breather Filter Motorbike 0.5in Universal Mini Air Intake Filter Vent Crankcase Breather Car Accessory (Black)

I had an aftermarket filter that doesn't provide enough air into the engine and was getting lean results on the obd scanner.Switch to this bad boy and was happy with the results. Sounds stock on idle but roars like a beast on high rpm on a motorway.Never had a lean scan on the obd after having this. Back for the buck!

I regret buying it,as I will not increase performance and damage your engine in time. Do your own research about pros and cons and decide for yourself. Doesn't work for me.(tested) can't ride in rain and needs to be coverd when washing your bike. Good product and delivery service.

Does the job
