Expert Manufacturing
NAPA® Echlin® Ignition Coils are designed and manufactured at our IATF 16949-certified facility in Bialystok, Poland. Spanning 145,000 square feet, our most advanced facility has more than 750 employees including 60+ resident engineers. At this plant, we manufacture more than 6 million ignition coils each year and introduce 110+ new products annually.
Simplified Core Separator
Simplified core separators extend the durability of the coil by compensating for thermal expansion.
NAPA Echlin’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 NAPA® Echlin® premium import ignition coil, the OE coil and two competitor coils.

Design Improvements
NAPA® Echlin® engineers made design improvements to numerous OE pencil coils. Take a look at our IC-655 NAPA® Echlin® import coil compared to the competitor's design. When you add up all of the NAPA® Echlin® design improvements, the end result is a heavy-duty, longer-lasting import ignition coil that is protected from moisture intrusion.
- The NAPA® Echlin® 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.

NAPA® Echlin® Outperforms the OE
NAPA® Echlin® 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 NAPA® Echlin® import coil. They tested both spark energy and discharge duration.
Let's take a look at the results below:
Testing Results:
-
The NAPA® Echlin® IC479 produces 22% more spark energy than OE.
-
The NAPA® Echlin® IC479 has a longer-lasting discharge (11%) than the OE.

More sections means less heat
Case Study: NAPA® Echlin® Ignition Coil (IC479)
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.
- NAPA® Echlin® with 9 sections only pushes 3.33 kV per section.
Solution: NAPA® Echlin® designed a new Coil to address OE weak points. These Coils are available in multi-packs.
The test results are in: NAPA® Echlin® 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
Our SMP Poland engineers subjected our NAPA® Echlin® IC479 coil and an OE coil to a 200-hour salt spray test. Just like before, the results speak for themselves.
The NAPA® Echlin® 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.

For nearly 100 years, when the OE failed, technicians have trusted NAPA® Echlin® to deliver a part that’s equal to or better than the original it’s replacing.
