Denso spark plugs and glow plugs
We distribute Denso spark and glow plugs in New Zealand, helping workshops and vehicle owners find the correct plug for the engine. The range covers everyday servicing and specialist applications, with different designs for different requirements.
Iridium TT and Nickel TT
Iridium TT combines a 0.4 mm iridium centre electrode with a 0.7 mm needle platinum ground electrode. Nickel TT uses Denso's twin-tip design with a 1.5 mm centre electrode. These are distinct ranges, so the application matters when selecting a replacement.
Iridium Tough and Iridium Racing
Iridium Tough is designed to limit electrode wear over its service life. Iridium Racing uses a fine 0.4 mm iridium centre electrode for motorsport applications. Our team can help you find the relevant specifications and check the correct part number.
Glow plugs for diesel engines
The Denso glow plug range serves a wide variety of diesel applications. Matching the plug to the engine and its control system is essential; use the specified replacement rather than choosing by appearance alone.
