DENSO-VK22(#5610)

This VK22 spark plug is engineered for modern petrol engines and features an iridium centre electrode for a focused, stable spark. A finer electrode needs less voltage to fire, which helps combustion efficiency, fuel economy and emissions performance.

Long-life electrode materials resist wear so the gap stays stable for longer. A quality ceramic insulator and plated shell help protect against fouling, heat and corrosion.

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.

Workshops can order with confidence for customer vehicles, and private owners can tackle routine maintenance knowing the part is made to suit the job. Pairing this part with a general inspection of the surrounding components is good practice, as related parts often wear at a similar rate. If you are unsure about fitment, send us your vehicle registration, make, model and year before ordering and we will help you confirm the right part. Every part is checked against its part number before dispatch, so what arrives matches what you ordered. Inspecting the old plugs as they come out can reveal useful clues about engine condition, such as oil consumption or a rich mixture. Our team is happy to answer questions about specifications, compatibility or ordering in larger quantities for fleet and workshop use. Buying the correct part the first time saves on labour, avoids repeat jobs and gets the vehicle back to work sooner. 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. Store spare parts in a cool, dry place in their original packaging until they are needed.
