Blue Streak® Import Coils

A Product of Superior Design

Blue Streak’s import ignition coils are the product of superior design, manufacturing, and testing. For example, take our UF549, one of the many new import ignition coils in our line.

    Flexible high-temp silicone boot withstands extreme heat for superior insulation

  • uf549-slider2png

    One-piece hi-dielectric strength housing withstands heat stress and secondary arcing for improved durability

  • uf549-slider3png

    Stainless steel spring resists corrosion

  • uf549-slider4png

    High-dielectric epoxy injected into case in vacuum to eliminate air pockets and prevent moisture intrusion

  • uf549-slider5png

    Upgraded brass mounting bushing outperforms the OE and competitors in salt spray environmental testing

  • uf549-slider6png

    Precision-wound 100% ETP copper secondary windings provide higher resistance to shorts and dielectric breakdown

  • uf549-slider7png

    Additional segmented bobbin sections prevent internal arcing and high-voltage breakdown

    More secondary bobbin sections compared to the OE coil

Simplified Core Separator

Simplified Core Separator

Simplified core separators extend the durability of the coil by compensating for thermal expansion.

Blue Streak’s precision-wound bobbin features more sections and simplified core separators to produce higher secondary voltage when required for better coil performance and longer service life. Our engineers conducted voltage tests featuring our Blue Streak® premium import ignition coil, the OE coil and two competitor coils.

Design Improvements

Blue Streak® engineers made design improvements to numerous OE pencil coils. Take a look at our UF-575 Blue Streak® import coil compared to the competitor design. When you add up all of the Blue Streak® design improvements, the end result is a heavy-duty, longer-lasting import ignition coil that is protected from moisture intrusion.

  • The Blue Streak® coil features one-piece housing and simplified press-fit; over-molded secondary terminal prevents moisture intrusion and ensures a secure secondary connection for a long-lasting, high-performing coil.
  • Other manufacturers’ two-piece housing and spring-clip design can lead to moisture intrusion, unwanted contact arcing and coil failure.

Blue Streak® Outperforms the OE

Blue Streak® coils outperform the OE, producing more spark energy and longer-lasting discharge for improved vehicle performance, fuel economy and emissions. Our SMP Poland Testing Lab conducted a performance comparison between the OE and our Blue Streak® UF-349 import coil. They tested both spark energy and discharge duration.

Let's take a look at the results below:

Testing Results:

  • The Blue Streak® UF-349 produces 22% more spark energy than OE.

  • The Blue Streak® UF-349 has a longer-lasting discharge (11%) than the OE.

More sections means less heat

Blue Streak Ignition Coil (UF349) case study compared to original equipment and competitor

Case Study: Blue Streak® Ignition Coil (UF-349)

Problem: Ignition coils on 2020-01 Nissan & Infiniti 3.5L V6s have a high failure rate. A typical system can produce up to 30 kV as needed.

  • Competitor N features 6 sections and is pushing 5 kV per section.
  • The OE features 8 sections and pushes 3.75 kV per section.
  • Blue Streak® with 9 sections only pushes 3.33 kV per section.

Solution: Blue Streak® designed a new Coil to address OE weak points. These Coils are available in multi-packs.

The test results are in: Blue Streak® coils have more secondary bobbin sections than both the OE and Competitor N. The additional section means less heat and a longer service life.

Made to Perform Under Harsh Conditions

Blue Streak Ignition Coil (UF349) compared to original equipment after 200-hour salt spray test

Our SMP Poland engineers subjected our Blue Streak® UF-349 coil and an OE coil to a 200-hour salt spray test. Just like before, the results speak for themselves.

The Blue Streak® coil with an upgraded brass bushing outperformed the OE in the salt spray environmental test with almost no corrosion, while the bushing on the OE coil rusted.
