Blue Streak Ignition Coils

Heavier-Duty Ignition Coils

Product of Superior Design

Blue Streak’s new heavier-duty ignition coils are the product of superior design, manufacturing and testing. For example, take our UF-303, one of the many heavier-duty ignition coils in our line.

Blue Streak® vs. OE Coil Comparison

To see what makes our Blue Streak® coils superior, we conducted a visual cutaway comparison against the OE. Here’s what we found:

  • blue-streak-vs-oeweb1png

    OE: 8 primary winding sections.

    Blue Streak®: With 10 primary winding sections, our design reduces the height of each section’s winding to decrease the risk of breakage between sections.

  • blue-streak-vs-oeweb2png

    OE: Uneven number of winding turns.

    Blue Streak®: Our barrel-winding distribution precisely reduces the number of turns in the first and last two sections to reduce the voltage gradient. When combined with our higher G2 insulation grade, our winding distribution lowers the risk of breakage within the winding.

  • blue-streak-vs-oeweb3png

    OE: Potted using “yellow” epoxy system.

    Blue Streak®: When compared to common “amber/yellow” epoxy systems, our “black” epoxy system features nearly 40% higher insulation resistance to voltage breakdown.

Blue Streak® Outperforms the OE

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 UF-303 and the OE:

Blue Streak<sup>®</sup> Outperforms the OE

Testing Takeaways

  • The two OE coils tested short-circuited after 68 hours and 140 hours, respectively.
  • The two Blue Streak® coils tested passed the 300-hour life test as well as 100 thermal cycles, a 24-hour life test and 10 thermal shocks.
  • Compared to the OE, Blue Streak® coils have 9% higher spark energy and 18% higher secondary voltage, which leads to better combustion of fuel mixture and reduced exhaust gas discharge.

"As testing shows, we’ve designed our Blue Streak Ignition Coils for superior performance and durability under the harshest conditions."

SMP Bialystok, Poland

Basic Manufacturing at Our State-of-the-Art Facility

Our IATF 16949 and ISO 9001-certified facility in Bialystok, Poland, is dedicated to the highest-quality manufacturing. Spanning 145,000 square feet, the facility serves as a basic design and engineering center for our Blue Streak® Ignition Coils.

The facility employs lean manufacturing methods such as the 5S philosophy and features a vertically integrated manufacturing process with multi-spindle winding, injection molding, potting, curing and welding. At the end of the day, the parts that leave our SMP Poland facility are manufactured for superior performance and durability.

End-of-life testing confirms polarity and continuity to ensure superior function.

Semi-automatic bobbin winding speeds up the manufacturing process.

All Blue Streak® Ignition Coils are laser etched with the Blue Streak® logo.

What's New

Many of the heavier-duty, longer-lasting ignition coils technicians trust from Blue Streak® are now available in popular Multi-Pack Kits.

We’ve identified several OE coils with high failure rates and recommend replacing in sets.
