Installation Notes and Quality

Verify connector shape, terminal style, and mount type before installation. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. NTK draws on OE sensor experience and subjects technical sensors to thermal shock, vibration, and OBD verification testing to meet or exceed OE specifications.
