CA18 Bosch Motorsport Coil Kit

HPR Nissan CA18 Bosch Motorsport Coil Kit
Upgrade the outdated factory CA18 ignition system with the HPR Nissan CA18 Bosch Motorsport Coil Kit for modern performance. 
 
This complete, plug-and-play ignition upgrade combines genuine Bosch Motorsport smart coils, a CNC-machined billet mounting bracket, and a motorsport-grade wiring harness designed specifically for the Nissan CA18 engine.
 
The short VAG-style Bosch Motorsport coils feature built-in igniters and provide more than twice the spark output of the original Nissan coils. This provides a stronger, more reliable ignition system for stock engines and high-boost performance applications.
 
HPR has tested the coil kit in-house with factory Nissan ECUs, allowing it to be installed as a direct upgrade without additional ECU tuning.
 
Bosch Motorsport Coils
The kit includes four genuine Bosch Motorsport coils with integrated igniters. Their compact design allows the coils to fit cleanly within the CA18 cylinder-head area while providing substantially greater ignition output than the original Nissan coil system.
 
Billet Coil Bracket
The mounting bracket is CNC-machined from a single piece of billet aluminum for strength, accurate coil positioning, and straightforward installation. Each bracket is black anodized for long-term surface protection and a clean, factory-style appearance.
 
Motorsport Wiring Harness
The included wiring harness is designed to support the increased current demands of the upgraded coils. It is constructed using motorsport-grade Spec 55 wire and protected with Raychem DR-25 heat-shrink sleeving for excellent resistance to heat, fluids, abrasion, and vibration. An ignitor-delete harness is also included, eliminating the factory external ignition amplifier when installing the smart coils.
