The VTC filter gasket (15845-RAA-A01) is a genuine Honda OEM part. It is a filter assembly for the VTC system and is compatible with all k20 and k24 engines from 2002-2015.
Replacing this part can fix the P2646 code, which is often caused by a lack of oil in the VTC solenoid. A clogged filter can also lead to a loss of oil pressure and prevent the engine from entering VTEC. If you are experiencing the P2646 code or performing a refresh on your engine, we recommend changing the VTC filter and gasket.
