Spark Plug DENSO Nickel TT KH16TT (4605)

The DENSO KH16TT spark plug (part number 4605) belongs to the innovative Twin Tip series, which provides ignition efficiency comparable to iridium plugs using nickel electrodes. The unique design with a protruding 1.5 mm diameter ground electrode significantly improves air-fuel mixture ignitability and engine stability at idle. Technical specifications include a heat range of 16, an extended thread reach, and reduced electrode diameters, which help lower the voltage required for the spark gap breakdown. This model is ideal for modern engines from Asian and European manufacturers that require high energy efficiency and reduced CO2 emissions. Using the KH16TT ensures reliable cold starts in low-temperature conditions and extends the lifespan of the ignition system by reducing the load on the coils. Denso spark plugs are manufactured in strict accordance with ISO global quality standards and are supplied as original equipment to leading automotive manufacturers.
