Maserati Ghibli


NGK has been selected as the exclusive supplier of original equipment (OE) spark plugs for the new Maserati Ghibli supercar.

It has developed a spark plug, the SILKAR8C6DG, which is as high-performance as the engines featured in the car – the first to carry the Ghibli name since 1997.

Based on the platform of the Italian prestige car manufacturer’s new Quattroporte, the Ghibli is one of the cornerstones of the Modena-based company’s plans to sell 50,000 cars per year by 2015.

NGK was selected as exclusive supplier of spark plugs for both versions of the petrol, turbocharged 3.0-litre V6 engine featured in the Ghibli.

The first delivers 330bhp, giving it a 0-62mph time of 5.6 seconds and a top speed of 163mph, while the second drives the even more powerful twin turbo charged 410bhp Ghibli S which has a 0-62mph time of just 5.0 seconds and a maximum speed of 177mph.

Tim Ward, Deputy General Manager – Sales & Marketing, NGK Spark Plugs (UK) Ltd, said: “Maserati is one of the most exclusive car marques in the world and it is a great accolade for NGK for our spark plugs to be specified as original equipment on the new Ghibli.

“The company wanted a high performance spark plug for a high performance car and that is what our OE team has delivered which is a tribute to NGK’s engineering prowess.”

The SILKAR8C6DG is a double precious metal spark plug, with a centre electrode Iridium tip of just 0.6mm diameter and a platinum chip on the ground electrode.

Thanks to the use of these precious metals, the electrode gap is only 0.6mm which provides perfect ignition even at highest charging levels and mixture turbulences and remains virtually unchanged over the 37,000-mile service life.

Additionally, the ground electrode features tapered edges to improve mixture accessibility and combustion stability. It also comes with a copper core, to further aid heat dissipation from the combustion chamber.

The spark plug is extremely slim, being designed with a long-reach M12 thread with a 14mm hexagon. As the spark plug requires less space, it gave Maserati maximum flexibility in engine design to allow more room for larger cooling passageways.

In addition the nickel plating of the plug’s metal shell provides excellent protection against corrosion.
