This part cross-references Dorman - HELP 20741 for the same application.

Common Issues This Part Can Help Address

• Engine misfire caused by weak or inconsistent spark output
• Rough idle during cold start or at operating temperature
• Hesitation or stumble during acceleration
• Reduced fuel efficiency from incomplete combustion
• Check engine light related to ignition coil performance

Installation Notes and Tips

Install on the engine head using the bolted mounting design and verify the 4-pin connector seats fully before operation. Because this is a direct ignition coil for electronic ignition systems, confirm the vehicle uses a flush-fitting pencil ignition coil layout and matches the listed Lexus fitment before replacement.

Assy/Disassy by Qualified Personnel Required. Inspect the coil boot, connector terminals, and surrounding ignition components during service to help prevent repeat faults.
