Bosch Coil Kit

Performance

• Approximately 80 mJ ignition energy.
• Designed to improve combustion efficiency.
• Intended to improve startup performance.
• Intended to improve lean and partial-throttle combustion.

Thunder Coil Kit

Performance

• Approximately 130–140 mJ ignition energy.
• Designed to provide stronger combustion and ignition stability under load.
• Intended to improve startup and high-performance fuel-burn efficiency.

Adjustable Coil Design

The Thunder Coil Kit features a patent-pending adjustable coil design.

• Coils can be rotated to suit loom direction and engine-bay layout.
• Straight or angled positioning is possible.
• Position can be set and locked using an Allen key.
• Captive screws prevent hardware from falling out during removal.

• Black anodised finish.
• Lightweight design.

Shared Coil Kit Features:

Connector & Compatibility

• Bosch and Thunder variants use the same connector design.
• The same loom and configuration can be used.
• Designed to fit stock ignition systems and aftermarket setups.

Gold-Plated Contact System

Gold-plated elements and contacts are designed to:

• Improve electrical conductivity.
• Reduce resistance at contact points.
• Reduce energy loss through heat.
• Help prevent corrosion at electrical contact surfaces.
• Support consistent spark delivery.

Coil Spring Design

• Larger-diameter coil springs.
• Protective coating.
• Multiple contact points.
• Designed to resist rust and corrosion in hot and humid environments.

Silicone Base

• High-quality silicone base.
• Operating temperature described as up to 250°C.
• Designed to provide strong clipping action and resistance to wear and tearing.

Waterproof Spark Plug Sleeve

• Padded sleeve design.
• Creates a watertight seal around the spark plug area.
• Designed to prevent water ingress and water collection around the spark plug tube area.

Hardware

• Stainless steel hardware.
• Designed to resist rust and corrosion.

Captive Bolt Design

A patent-pending design keeps the mounting bolt retained in the coil during removal, helping to prevent:

• Dropped hardware.
• Lost bolts.
• Bolts falling into the cylinder area.
• Incorrect bolts being used.

Electrical Connector

• Slim three-pin connector.
• Locking screw mechanism.
• Designed to prevent accidental disconnection.

Wiring Harness

All coil kits are supplied with a wiring harness.

The wiring is described as:

• Motorsport-grade.
• Tefzel sealing.
• MIL-spec wiring.
• Designed for harsh motorsport and performance environments.

Compatibility
