• High-temp boot prevents high-voltage leaks, while stainless-steel spring with internal ferrite noise suppressor prevents radiofrequency interference (RFI)
• Our ignition coils use 100% pure copper windings in the primary and secondary bobbins to improve durability and provide higher resistance to internal shorts and dielectric breakdown
• Manufactured in Poland
• Advanced bobbin technology, highly specialized silicone magnetic steel core, and optimized winding all provide an accurate high energy output to restore engine performance
• Application-specific engineering
• Engineered and tested to meet OE spark energy output, impedance, and durability in all operating conditions.
• High-dielectric epoxy injected into case and pulled into vacuum to eliminate air pockets and prevent moisture intrusion or internal energy loss
