Powerful spark

2 September 2013  

Two Twin Tip (TT) spark plug references join Denso’s ignition programme. TT plugs are the first ever fine-wired spark plugs to be made without precious metal on the electrodes. A nickel alloy centre and a ‘twin’ protruding ground electrode has a slimmer than normal 1.5 diameter – producing more powerful sparks and better combustion. The firm says drivers notice a more responsive engine and more torque when pulling away. The XU22TT reference can be used on the Fiat, Alfa Romeo and Lancia 1.2 and 1.4 FIRE engine, 2009 onwards Ford Ka, Chevrolet 1.0, 1.2 and Daihatsu 1.3. The second reference, XUH22TT, fits the Kia/Hyundai 1.4 and 1.6 engines and is suitable for the Smart 1.0 engine. The range includes 15 part references in total, covering 85% of Europe’s top-selling cars.
