DENSO-ITV22(#5340)

The ITV22 spark plug is a high-performance ignition plug featuring an iridium centre electrode, built for strong, consistent sparks and dependable starting. A finer electrode needs less voltage to fire, which helps combustion efficiency, fuel economy and emissions performance.

The insulator is designed to resist carbon fouling and flashover, while the corrosion-resistant shell and threads make installation and future removal easier. The plug is made to hold its gap over a long service life.

Fitment and installation

Confirm the part number against your vehicle's specification or the plugs currently fitted, paying attention to thread size, reach, hex size and heat range. Fit to a cool engine, thread the plug in by hand first to avoid cross-threading and tighten to the manufacturer's torque value. Fine-wire plugs are pre-gapped, so avoid levering the electrode. Replace plugs as a full set for an even engine balance.

Always follow the vehicle manufacturer's service schedule and fitting instructions, and have the work carried out by a qualified technician if you are not confident doing it yourself. Pairing this part with a general inspection of the surrounding components is good practice, as related parts often wear at a similar rate. Quality replacement parts like this help keep running costs predictable and reduce the chance of an unexpected roadside breakdown. Store spare parts in a cool, dry place in their original packaging until they are needed. Regular maintenance with dependable replacement parts protects the value of your vehicle and helps it pass its next Warrant of Fitness or Certificate of Fitness inspection. Inspecting the old plugs as they come out can reveal useful clues about engine condition, such as oil consumption or a rich mixture.
