Installation Notes and Tips
Verify the part number and match the vehicle application before installation. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. For best results, inspect spark plugs and related ignition components during service, since worn plugs can place added demand on the coil.
