What It Helps Address

• Engine misfire caused by a weak or failing ignition coil
• Rough idle and inconsistent spark output
• Hard starting related to ignition coil wear
• Loss of power under load in Toyota and Lexus applications
• Check engine light conditions tied to ignition performance

Installation Notes

Verify the vehicle year, make, model, and fitment note before ordering. Some applications require an OE part number match, engine-code match, or a production-date cutoff such as Toyota Tundra through 10/2010 or Camry through 11/2005. This part cross-references OE-style application references including Toyota 90919-A2001 for select Corolla and Matrix fitments.
