These high-performance spark plugs operate based on the state-of-the-art surface air-gap principle. It is the first spark plug with four thin ground electrodes and silver-plated central electrode.

Designed to be a long lasting spark plug, the Bosch Super Plus Spark Plug uses a ‘Yttrium-enhanced’ copper core centre to provide far greater service life than OEM specified plug. This plug also boasts improved starting in cold weather thanks to the tapered, v-profile nickel chromium ground electrode. The angular, five-ribbed insulator design also relieves any chance of misfires happening due to current leakage. This plug is ideal for replacing factory spark plugs with the added benefit of 50% longer performance life.

 This technological superiority is also evident in the engine's performance, in all driving situations, over the entire life of the spark plug.

An Overview of the Benefits:

• Noticeably improved acceleration
• Significantly smoother engine running
• Superior engine elasticity
• Factory pre-gapped electrodes
• Higher ignition reliability thanks to eight possible ignition gaps
• Self-cleaning thanks to surface air-gap technology
• Increased thermal range: up to three times as many cold starts possible as with conventional spark plugs
• Increased environmental protection and protection for the catalytic converter

And the Super 4 spark plugs can also be used in older vehicles, allowing them to experience the benefits of state-of-the-art spark plug technology.
