Mercedes-Benz 420SEL Spark Plug

Why you drive your 420SEL.

It's not a regular occurrence that you discover you need a replacement Spark Plug to fix your vehicle. Obviously, you didn't buy your 420SEL unless you understood you would be getting long-lasting quality and a trusted brand both rolled up into one car, truck, or SUV. When your Mercedes-Benz 420SEL rolled off the assembly line, it was destined for a person with discerning taste who prioritizes German engineering in their automobile. You purchased your 420SEL because its performance and European styling struck a chord inside you; so why would you be okay with second rate when it comes to superior quality auto parts?

What Spark Plug does for your vehicle.

There are ignition parts in your engine so small that they can be forgotten about when performing regular maintenance. 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. If one of the spark plugs wears out, the engine in your Mercedes-Benz 420SEL will not turn as hard; reducing power and gas mileage while increasing harmful emissions.
