DENSO Spark Plugs

World's leading pioneers of OEM quality spark plug technology since 1959

  • Nickel TT

    Nickel TT

    • First ever fine-wired Spark Plug without precious metal on electrodes
    • Slimmer ground and center electrodes provide better ignitability than a Standard Plug
    • Less stock, same coverage: Nickel TT plugs cover many applications with fewer part references!

    U-groove technology

    • Better fuel economy:
      U-groove can ignite leaner mixtures, leading to fewer misfires
    • Efficient combustion, lower emissions:
      U-groove allows the spark to expand and fill the gap created by the ‘U’ shape

  • Platinum Longlife

    Platinum Longlife

    • 1.1 mm Platinum centre electrode and Platinum tipped ground electrode ensure optimal performance
    • Platinum’s superior resistance to erosion and corrosion enables DENSO Platinum plugs to create a spark plug capable of consistent, extended operation of up to 100,000 kilometres
    • Requires less voltage to ignite the air/fuel mixture
