Tired of poor gas mileage and a shaky ride? Faulty ignition coils can cause high fuel consumption, engine jitter, and a loss of power. Our high-performance coil and iridium plug combo delivers a stronger, more consistent spark for optimal combustion. This translates to smoother idling, restored acceleration, improved fuel efficiency, and reliable starts in any condition—giving you back the pep your car had when it was new.
Built tough for lasting reliability. These ignition coils are constructed with premium copper windings and sealed with high-insulation epoxy resin. This advanced design prevents moisture intrusion and thermal breakdown, dramatically enhancing heat and wear resistance. Paired with long-life iridium spark plugs, this set provides stable voltage transfer and consistent performance through thousands of miles of demanding driving.
Solve multiple issues in one simple upgrade. This complete set addresses common problems like check engine lights (P0300-P0304 misfire codes), rough transmission shifts linked to engine hesitation, slow starts, and spark plug fouling. Replacing both coils and plugs together as a matched system ensures balanced performance. Enjoy a straightforward, DIY-friendly installation that requires only basic tools and gets you back on the road quickly.
