Are bosch double platinum spark plugs good

Key Features

Frequently Asked Questions

Bosch precious metal spark plugs are pre-gapped at the factory and do not require a gap adjustment. Adjusting the gap may damage the center and ground electrodes.

The Bosch OE Fine Wire Spark Plug family consists of Double Iridium, Double Iridium Pin-to-Pin, Iridium, Double Platinum and Platinum spark plugs. Built around Original Equipment (OE) technology, these spark plugs have an OE-specific design and are manufactured to meet or exceed OE requirements. As direct injection continues to grow across all makes (Domestic, Asian, and European vehicles) and as ignition systems continue to increase in voltage output, things like advanced ceramic technology, spark position and correct gap are more critical than ever. Bosch created this line of OE equivalent spark plugs for the aftermarket to address these performance requirements.

Bosch guarantees you will feel improved performance in your vehicle when using any of Bosch OE Fine Wire Spark Plugs (Double Iridium, Double Iridium Pin-to-Pin, Double Platinum and Platinum). However, if you do not experience quicker starts, smoother acceleration and improved fuel efficiency, you can return the plugs with a dated sales receipt and Bosch will refund the purchase price of the spark plugs.

EVO Spark Plugs

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 Double Iridium Spark Plugs are engineered to deliver both high performance and long life, representing advanced original equipment (OE) spark plug technology. The ultra-fine wire design and laser welded tapered ground electrode deliver optimum performance, while the iridium center electrode and ground electrode help it to go the distance. Unlock the performance in your engine with Bosch Double Iridium Spark Plugs.

Bosch Double Iridium Pin-To-Pin Spark Plugs represent advanced OE spark plug technology and are manufactured to be original equipment (OE) equivalent in fit, form and function. The ultra-fine wire design firing pin and ground electrode pin provide higher performance.

Iridium Spark Plugs

Bosch Iridium Spark Plugs are engineered to deliver both high performance and long life, representing advanced OE spark plug technology. The ultra-fine wire iridium center electrode pin delivers best performance. Unlock the performance in your engine with Bosch Iridium Spark Plugs.

Bosch Double Platinum Spark Plugs are engineered for up to 3X longer service life.*

Bosch Platinum Spark Plugs are engineered for up to 2X longer service life.*

Copper with Nickel Spark Plugs

Bosch copper core spark plugs feature a heavy-duty nickel center electrode for longer lasting service life compared to standard copper plugs.

Silver 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.

Platinum+4 Spark Plugs

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.
