I finally found knock sensor for my car and i also ordered the genuine hydraulic tensioner for RVR. Total $231 AUD delivered directly from Japan.
This place sales almost all parts for rvr and other mitsubishi cars all you need is a part number. If you need something give me a part number and I'll check for you.
