Mercedes-Benz 420SEL Spark Plug

Keeping your 420SEL in top shape is your top priority.

Select Your VehicleYou bought your 420SEL because its performance and German engineering struck a chord inside you; so why would you settle for second best when it comes to superior quality auto parts? Obviously, you didn't buy your 420SEL unless you wanted to buy long-lasting quality and dependability both impeccably combined into one vehicle. Anyone who drives a Mercedes-Benz knows that when it comes to maintaining their vehicle only the most superior replacement parts will do. The vehicle in your driveway symbolizes the best in class when it comes to all the vehicles in today's marketplace.

Don't go too long without fixing your Spark Plug... here's why.

Some engine parts are tucked away out of sight, so they are often overlooked. The job of detonating the air/fuel mixture in the combustion chambers in the engine is your Mercedes-Benz 420SEL spark plug. Several different metals (copper, platinum, iridium) can be used for the spark plug's electrode on all current models. Should a spark plug fail to do its job, the engine in your Mercedes-Benz 420SEL will not turn as hard; reducing power and gas mileage while increasing harmful emissions.
