DENSO has been setting the standard for spark plug technology since 1959. They develop all of their ranges in-house, and manufacture them in their own ISO9000 certified factories worldwide - with 'zero defects' as standard. They also provide this outstanding OE quality to the aftermarket. Including Standard, Platinum and Iridium, DENSO Spark Plugs cover a complete range of continually updated references. Guaranteeing optimum engine performance, choose DENSO Spark Plugs for every automotive, motorcycle, marine and small engine application.

DENSO's Twin Tip Plugs use a tip shape for the ground electrode, in addition to the tip shape of the centre electrode for conventional spark plugs. This unique structure results in improved ignition performance for a more powerful and fuel-efficient combustion. The nickel alloy contacts enables the centre electrode to be made 40 percent thinner than that of conventional nickel spark plugs. When the spark generated by a spark plug grows during combustion with the air-fuel mixture, it loses heat when it comes into contact with electrodes and ignition performance decreases. Thinner electrodes result in less obstruction of spark growth (quenching), meaning better ignitability.

We've tried to keep all other shipping costs as low as we can.

Carriage starts at just £0.95 (inc VAT) for small items, with our most common courier rate set at £5.99 for orders of 5kg (enough for 5 litres of oil).

  • *Free shipping is available for UK Royal Mail, UPS Access Point™ (click & collect) and standard UK courier services (not express / priority / islands).
  • Courier surcharges mean we are unable to offer free "to the door" courier shipping from us in Cornwall up to Highlands / Grampian in Scotland - and because we send a lot of liquids, not every courier option is available to us.
