Restore Power & Fuel Economy – Faulty ignition components cause rough idling, misfires, reduced gas mileage, and “check engine” lights. Our premium coils deliver a stronger, more consistent spark, restoring engine performance, improving throttle response, and maximizing fuel efficiency. Tested for high-RPM durability.
Premium Build & Easy Installation – Coils feature a high-impact housing and neodymium magnet core for superior voltage output. Wires use a ferromagnetic Kevlar-reinforced fiberglass core with high-temp silicone insulation for excellent heat/oil/abrasion resistance. Pro tip: Apply dielectric grease to boots during installation to prevent cracking and ensure a secure seal.
