Performance ignition coils for BMW N55/S54/S55/S63 engines.

Ensure adequate ignition with QT ignition coils.

The QT Ignition Coil is a more affordable, longer lasting and more tune-friendly alternative to the OEM ignition coil. No more broken coils and misfire codes.

More efficient ignition energy (+10% vs. OEM)

Higher energy transfer ensures optimal spark throughout the dwell time, improving ignition efficiency, especially in tuned and high-revving engines.

For hard driving - Better spark formation with high boost pressure

Ensures ignition performance even at high boost pressures and rich mixtures, which promotes cleaner combustion and better efficiency.

Save money - Longer service life and mechanical durability

Advanced insulation materials and a winding structure that reduces thermal stress prevent overheating and internal short circuits, extending the component's lifespan.

Forget about misfires - More stable performance under heavy loads

Designed to withstand continuous stress — the right choice for high-performance and tuned engines that require reliable ignition voltage across the entire load range. (where the OEM ignition coil fails)

Heat resistance up to 140 °C

Operating temperature in continuous use up to 120 °C – performance remains stable even at high temperatures without loss of power. (see comparison with original)

Optimized primary and secondary windings

The increased number of turns and high-quality copper wire improve current conductivity and ensure high, consistent ignition voltage even under heavy use.

• At less than 1.5 milliseconds, the performance of both sides is still at the same level.

• When the duration increases to 2.0 milliseconds, the energy delivery of the original coils begins to decline significantly, but the QT coils maintain stable power.

• At 3.0 milliseconds, QT coils produce up to approximately 25% more energy – a significant advantage in tuned or high-revving engines.

• Even at high temperatures of 140°C, QT coils maintain a stable energy level of 70 mJ, while original coils suffer a significant power reduction or stop working altogether.
