Frequently Asked Questions
Do these ignition coils and spark plugs also work without tuning?
Yes. They are suitable for standard engines as well as for Stage 1 to Stage 3 builds.
Do I need to make any adjustments to the wiring loom or connectors?
No. The kit is plug-and-play on the OEM connectors.
Do these upgrades provide more power?
Indirectly. A stronger and more stable spark improves combustion, which can enhance performance and responsiveness, particularly at higher boost pressures.
What spark plug gap do you recommend?
Follow your tuner’s advice. At higher boost levels, a slightly smaller gap is often used to prevent the spark from blowing out.
