Set of 8. We have standard USA coils available in another listing.

Blue Streak Heavy Duty

Blue Streak delivers heavy-duty improvements not featured in the original, making it the perfect match for any technician who commands the very highest quality. Suited for standard and high performance engines where the ultimate in ignition is required.(We use these in our Boss camshaft and boosted packages.)

Features & Benefits:
 
Engineered and tested to exceed OE for spark energy output, impedance, and durability
Tested at extreme engine performance condition at 7200 RPM
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 ensures superior bond to epoxy for 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 (44 gauge) copper wire ensure high-voltage availability for peak performance while reinforced bobbins prevent voltage flashover for extended service life
Copper wires using higher insulation grade ensure heat resistance and prevent high voltage breakdown
Optimum wire distribution developed by extensive testing ensures superior functional parameters and durability
Isolator manufactured using high voltage-resistant thermoplastics to prevent premature coil failure
