If you are looking for a highly ignitable, high quality, durable spark plug without the costs usually associated with high performance plugs, then look no further. A true world first, DENSO’s patented twin tip (TT) spark plugs feature a nickel centre and a ‘twin’ protruding ground electrode with a slimmer 1.5mm diameter.

A true world first, DENSO’s patented twin tip (TT) spark plugs feature a nickel centre and a ‘twin’ protruding ground electrode with a slimmer 1.5mm diameter.

The DENSO difference:

• The first ever fine-wired Spark Plug without precious metal on the electrodes
• Slimmer ground and centre electrodes provide better ignitability than a Standard Plug
• Less stock, same coverage: TT Plugs cover many applications with fewer part references
• Aimed at drivers who care about value for money and savings on fuel

DENSO's revolutionary Twin-Tip design

The additional tip on the ground electrode results in less obstruction of spark growth, while still maintaining the same gap. Less interference at the spark origin (quenching) means better ignitability for a more powerful and fuel efficient combustion.

Due to its excellent ignitability there is better combustion - even with leaner mixtures, resulting in less misfiring than a standard plug. Tests show that when comparing a Standard Plug to a TT Plug, fuel consumption improves by up to 5%, meaning those regular and longer journeys become more economical.

The complete Nickel TT Spark Plugs range is highly consolidated, comprising of 19 convenient part numbers that together offer an impressive coverage of top selling Australian car parts.
