Keep your ignition system in good order with NGK spark plugs selected for fast-road applications.

Ideal for servicing your road car or completing a performance build, fresh spark plugs help maintain consistent ignition when the existing plugs are worn or due for replacement.

Correct specification matters more than simply fitting a plug labelled “performance”. Always choose the appropriate fitment and heat range for your engine and its state of tune.

A Sensible Part of Your Maintenance

Spark plugs operate in demanding conditions and wear over time. Worn or fouled plugs can contribute to misfires, difficult starting and uneven running.

Replacing plugs at the appropriate service interval helps keep the ignition system working as intended—particularly on a car that regularly sees enthusiastic road use.

Fitting new spark plugs does not guarantee an increase in horsepower. Any improvement will depend on the condition of the existing plugs and the overall engine setup.

Choosing the Correct Specification

Check the listed application and NGK part number before ordering.

For modified engines, particularly turbocharged or supercharged applications, the required heat range and electrode gap may differ from the standard specification. These should be confirmed with your engine builder or tuner.

A colder plug is not automatically an upgrade for every engine.

Installation

Install with the engine cold and follow the applicable fitting guidance for your engine and plug type.

Check the required electrode gap and tightening torque before installation. Take care when handling the plugs to avoid damage to the ceramic insulator or electrodes.

Professional installation is recommended if you are unsure of the correct procedure.

12-Month Warranty

Supplied with a 12-month warranty against manufacturing defects.

Spark plugs are service items. Normal wear, fouling, incorrect installation, an unsuitable heat range or gap, and damage caused by engine faults or incorrect tuning are not covered.

This warranty does not affect your statutory rights.
