Spark Plugs

product-image

Today’s turbocharged gasoline direct injection engines place high demands on spark plugs. To meet these needs, the new Bosch EVO spark plug is engineered to ensure reliable ignition throughout its long service life – even under extreme conditions in modern engines.Thanks to its improved insulator design and high dielectric strength (greater than 45 kV), the new EVO spark plugs can withstand irregular combustion – known as mega knocking – that can occur in modern, technologically advanced engines. Bosch EVO spark plugs are developed and produced with the same high quality as original equipment spark plugs.

Bosch Silver Spark Plugs are engineered for older European performance cars, as well as some motorcycle applications. These types of vehicle engines operate at particularly high combustion chamber temperatures, increasing the wear on the electrodes. Bosch uses silver alloys in the center electrode tip to resist wear and improve spark plug efficiency.

Bosch Platinum+4 Spark Plugs deliver smoother acceleration, top fuel economy and ultimate engine performance. Bosch Platinum+4 Spark Plugs reach self-cleaning temperatures faster for quicker starts, smoother acceleration and increased fuel efficiency.


product-image

The Bosch Double Iridium Spark Plug was optimized for customers operating in landfill and biogas applications looking for longer service life. The large, 2.4mm high content iridium center and ground electrode resist wear and erosion caused by biogas applications. Test results have shown over 4,500 hours on a CAT 3520 running landfill gas – 50% longer than the previous plug used. Longer run times reduce engine downtime. The result, reduced operating costs and higher revenue for the operator.

The Bosch Double Platinum Spark Plugs combine over one hundred years of spark plug engineering experience with robust construction of the highest quality heavy duty components. The result is a superior platinum/iridium spark plug which exhibits unsurpassed reliability and a greatly extended service life. Precious metals in both the center and ground electrodes provide exceptional resistance to wear.
