New glow plug introductions bring a further 12 million vehicles within reach

As a diesel pioneer and a leading original equipment (OE) manufacturer, DENSO glow plugs set the standard as they are engineered to reduce emissions, utilise advanced heating technology to ensure quick engine starts, deliver greater fuel efficiency and provide exceptional durability. 

Reflecting its position as a major OE supplier to vehicle manufacturers (VMs) globally, DENSO’s aftermarket range is in continuous growth as it constantly brings its OE solutions into the reach of the independent service and repair sector throughout Europe.

So, with the introduction of nine new part numbers into its glow plug offering, the company has provided a solution for 42 OE part numbers that cover 721 applications and cater for more than 12 million vehicles.

Emphasising the breadth of the vehicles covered by these nine new additions, they address the requirements of multiple models from VMs including Audi, Citroën, DS, Ford, Hyundai, Kia, Nissan, Opel, Peugeot, Renault, Seat, Škoda and Vauxhall. This degree of coverage is also a major benefit to wholesalers when it comes to stock holding levels, as this consolidated range means there is less pressure on warehousing, which further aids their cost controls.

Although diesel engines generally don’t have the same range of potential starting problems as their petrol cousins, winter conditions can still expose issues, which could well require glow plugs to be replaced, and fitting DENSO plugs will provide the ideal replacement solution.

This is because DENSO glow plugs are designed to reduce emissions and provide quick, smooth starts, even in the coldest weather. They feature advanced double coil technology, for exceptional durability with efficient post heating, which ensures optimised combustion, lower emissions and greater fuel efficiency.

As the heating element is the most critical component of the glow plug and allows it to fulfil its role in the ignition system, its functionality has to be verified during the production process. It is for this reason, that at the end of the production line, the performance of each DENSO glow plug is thoroughly tested to ensure that it is working in accordance with the given specification, including its heat-up time and the temperature it needs to reach. This in line production test causes the glow plug’s tip to take on a grey/blue tone.

This colouration is due to the oxidation of the metal, which is accelerated by the high temperature it is subject to during the test, but it does no harm to the glow plug, nor does it degrade its performance. In fact, it should be looked at by wholesalers as a further assurance of the plugs capacity to deliver reliable, long term performance.
