DENSO Innovation – 25 Years of Ceramic Glow plugs

Driven by quality; DENSO is the OE supplier for Glow plugs to Toyota, Mitsubishi and Mazda, and brings this OE quality to its aftermarket customers. The DENSO Glow Plug programme is the leader in scope and performance; drawing on the company’s heritage as an innovator in OEM Diesel systems.

DENSO’s bold step in 1991 to produce of the first OE Ceramic Glow plug headed the Diesel market it into new territory, and led the way in terms of technical innovation and manufacturing quality. DENSO’s Ceramic Glow plugs have since become a prominent mainstay in diesel vehicles and the aftermarket, due to their increased lifetime and vital emissions reduction.

The Ceramic heating coil is much more heat-resistant, meaning the DENSO Glow plug can reach extremely high temperatures up to 1,100°C, greatly increasing its service life.

DENSO’s OE quality allows fast pre-heating and extended post-heating from a cold start; reducing engine emissions and noise, while maintaining greater resistance to erosion – producing a glow plug with a greatly extended lifetime, and unmatched reliability.

The Ceramic Glow plug is just one aspect of DENSO’s extensive OE product range, which encompasses all current metal Glow Plug technologies including double coil and extended post-heating.

DENSO’s Instant Heating Glow plug further enhances the leading product, with precise high voltage heat up properties reducing heating time to just 3 seconds.

DENSO’s full Glow plug range covers 91% of the car parc and consolidated to only 137 part numbers that still cover over 6,000 applications, ensuring near-universal suitability for Diesel engines.
