VR6 valve guide conical BAR-TEK® BAR-TEK Motorsport 21vr064 - сервиз

12 New valve guides for VR6 engines conical for better air flow. The conical shape improves the air flow rate in the channel of the cylinder head. This allows the engine to take more mixture and the filling is positively influenced. New valve guides should be used if the old ones show too much wear. When using new valves, be sure to replace the valve guides as well. After installing new valve guides, be sure to rework or adjust the valve seat.
