Installation Notes and Tips

Verify the vehicle’s ignition system and match the confirmed application before installation. Route each lead to avoid contact with hot exhaust components, sharp edges, or moving parts, and compare the existing wire routing to the replacement set before removal. For Buick Regal, Buick Riviera, and Pontiac Bonneville applications, confirm whether the vehicle uses the standard ignition setup or the Delco ignition system listing shown in the fitment data.

Use the part number 51217 to confirm ordering accuracy, especially when cross-checking Buick, Oldsmobile, and Pontiac ignition service parts. This part cross-references DENSO Auto Parts (e.g., 671-6009) and Delphi (e.g., XS10209) for the same application.
