Jaguar 420 Spark Plug

Great cars and trucks like your 420 need great parts.

Obviously, you didn't buy your 420 unless you understood you would be getting best-in-class service and a trusted brand both rolled up into one car, truck, or SUV. The vehicle in your driveway symbolizes the best in class when it comes to all the cars, trucks, and SUVs these days. Your Jaguar dealership isn't the only place to buy genuine or original equipment quality parts to repair your 420. Anyone who operates a Jaguar knows that when it comes to fixing their automobile only the highest quality replacement parts will do.

Why Spark Plug replacement is so important.

There are ignition parts in your engine so small that they are often overlooked. The job of creating a spark in the combustion chambers that ignites the air/fuel mixture in the engine is your Jaguar 420 spark plug. Several different metals (copper, platinum, iridium) can be used for the spark plug's electrode on all current models. When one of the spark plugs does not fire when it should, the engine in your Jaguar 420 will not turn as hard; leading to an increase in unburnt hydrocarbon emissions and a decrease in horsepower and fuel economy.
