Pre order / made-to-order products

If the product you have ordered is a pre order or made-to-order item, it is not subject to the 14-day right of withdrawal or return under consumer protection laws, as the product is manufactured or sourced specifically based on the customer’s individual order.

If you wish to cancel your order before receiving the product, we will refund 50% of the total order amount.

This condition applies to the following product categories:

• Suspension
• Engine Tuning
• Engine Parts
• Exhaust Systems
• Fueling
• Turbochargers/superchargers
• Drivetrain
• ECE-approved Downpipes

All of the above products are manufactured or sourced individually based on the customer’s order, and therefore cannot be returned after delivery, unless the product has a manufacturing or material defect.

In the event of such a defect, the standard liability for defects as provided by consumer protection legislation shall apply.

HG-Motorsport High Performance Ignition Coils

Maximum ignition energy and excellent heat resistance for modern performance engines

In modern vehicles, especially in tuned and performance-enhanced engines, original ignition coils quickly reach their performance limits. This can lead to ignition misfires, uneven combustion, and problems due to thermal load.

HG-Motorsport High Performance Ignition Coils have been specially developed to address these challenges. They offer greater ignition energy, improved heat resistance, and consistent, reliable performance even under the most demanding operating conditions.

Technical Specifications of HG-Motorsport Ignition Coils

• Optimized Primary and Secondary Windings
  A higher number of turns and high-quality copper wire improve energy transfer and maintain high ignition voltage.
• Increased Ignition Energy (+10% compared to original coils)
  Ensures optimal energy supply to the spark plugs throughout the dwell time, which is especially suitable for powerful engines.
• Consistent Energy Delivery under High Load
  An excellent choice for turbocharged and supercharged engines that require stable ignition voltage during prolonged load periods.
• Longer Lifespan
  High-quality insulating materials and optimized winding structure reduce thermal stress and protect against internal short circuits.
• Excellent Heat Resistance
  Continuous operation up to 120 °C and stable performance up to 140 °C without performance degradation.
• Optimized Spark Formation
  Stable ignition even at high boost pressures and richer mixtures, which significantly improves combustion efficiency.

Ignition Energy Compared to Standard Ignition Coils

Measurements show a clear advantage of HG-Motorsport ignition coils compared to original ignition coils:

• Up to 1.5 ms: Both coils produce almost the same amount of energy.
• After 2.0 ms: The energy of standard ignition coils clearly begins to drop, while HG-Motorsport coils maintain a high energy level.
• At 3.0 ms: HG-Motorsport coils produce almost 25% more energy, which is particularly important at high RPMs and in tuned engines.
• At 140 °C: HG-Motorsport coils maintain approximately 70 mJ of ignition energy, while original coils are already at their operational limits or fail.

Especially Suitable for

• Powerful and tuned engines
• Racing and track use
• Performance-tuned cars for daily driving
• Replacing original OEM ignition coils for improved reliability and lifespan

Construction and Operating Principle

The ignition coils use an optimized primary and secondary winding structure.

The primary winding creates a strong magnetic field, which, upon collapse, induces a high voltage in the secondary winding. Thanks to a higher number of turns and improved insulation, the ignition energy remains constant even at high RPMs and load peaks.

Thermal Tests and Long-Term Trials

1. Long-Term Thermal Load Test

Test Setup:

• Continuous operation at 120 °C
• Simulated load fluctuations
• Test duration 100 hours

Results:

• HG-Motorsport ignition coils showed no degradation in performance or thermal damage.
• OEM ignition coils lost approximately 25% of their energy after just 50 hours, after which initial material changes were observed.

Additional Test at 140 °C

HG-Motorsport

• Stable operation for over 8 hours without malfunctions.

OEM Ignition Coils

• Up to 40% power reduction after 4 hours.
• Subsequently, thermal failures occurred.

Summary of Laboratory Measurements
