Designed and manufactured to SMP’s strict quality standards, so you can install with confidence. Engineered and tested to match OE for spark energy output, impedance, and durability. Advanced thermoplastic coil connector ensures proper connection and resists fractures caused by heat and thermal cycling. High-temp boot prevents high-voltage leaks, while stainless-steel spring with internal ferrite noise suppressor prevents radiofrequency interference (RFI). High-impact housing material bonds extremely well to epoxy to ensure longer life in all operating conditions. Internal, neodymium permanent magnet core surrounded by grain-oriented, magnetic-laminated steel maximizes high-voltage output at all speeds. Primary (25 gauge) and Secondary (43 gauge) copper wire ensure high-voltage availability for peak performance while reinforced bobbins prevent voltage flashover for extended service life. Isolator manufactured using high voltage-resistant thermoplastics to prevent premature coil failure.
