A coil-on-plug performs the functions of the ignition coil (creating the spark energy) and the spark plug wire set (containing and delivering the high voltage energy to the spark plug). To ensure proper function, Standard® Coil-on-Plug Assemblies feature premium-quality components.
Designed using advanced thermoplastics to ensure proper connection and resist fractures caused by heat and thermal cycling
High-temp boot prevents high-voltage leaks, while stainless steel spring with internal ferrite noise suppressor prevents radio frequency interference (RFI)
High-impact material bonds extremely well to epoxy to ensure longer life in all operating conditions
Internal neodymium permanent magnet surrounded by grainoriented 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
Manufactured using high-voltage resistant thermoplastics to prevent premature coil failure
We performed an extensive engineering analysis of OE DG500 and DG508 compared to Blue Streak® FD-502 and FD-503. The engineers measured winding resistance, inductance and output voltage, spark, energy, waveform peak voltage and ringing, as well as a complete physical and sectioned comparison to OE.
|WINDING RESISTANCE / INDUCTION AND OUTPUT VOLTAGE / SPARK ENERGY|

Blue Streak® Ignition Coils look, fit and perform like the original they replace with 100% end of the line production testing. The Blue Streak® coils also provide an improved secondary winding design (additional winding bays) that helps prevent internal arcing and high-voltage breakdown.
The Blue Streak® coils match or exceed the OE coils in all categories and are an excellent replacement exceeding the OE performance.
All products manufactured at our IATF 16949 and ISO 9001-certified facility in Poland undergo extensive measurement and life testing, in addition to a full range of environmental analysis that includes thermal shocks, thermal cycling and vibration tests, just to name a few. To see what goes into our coil testing, take a look at this competitor comparison between our UF303 and the OE:
"As testing shows, we’ve designed our Blue Streak Ignition Coils for superior performance and durability under the harshest conditions."
