Frequently Asked Questions (FAQs)

Correct spark plug gap is critical for ignition efficiency. By pre-gapping each plug before dispatch, we ensure consistent performance and eliminate the risk of customers installing plugs with an incorrect gap.

The plugs are checked and set by us prior to dispatch. However, as with any spark plug installation, it is good practice to visually check them before fitting.

Iridium plugs feature a very fine centre electrode that requires less voltage to fire. This produces a stronger spark, improves combustion efficiency, and offers a much longer service life compared to traditional spark plugs.

Yes. NGK Iridium plugs are widely used in performance and motorsport applications due to their reliability under higher cylinder pressures, we recommend fitting NGK Iridium Plugs when servicing your vehicle or when running our software.
