GMC K25 Spark Plug

Why you drive your K25.

Obviously, you didn't buy your K25 unless you wanted to buy performance and great value both rolled up into one vehicle. It's not a regular occurrence that you realize that you have to buy a replacement Spark Plug for your automobile. Anyone who operates a GMC knows that when it comes to maintaining their automobile only the most superior replacement parts will do. Car aficionados appreciate the a brand you can trust built into each GMC, and know that only the best repair K25 parts will suffice when maintenance needs to be done.

The function and purpose of Spark Plug.

Some engine parts are tucked away out of sight, so they can be forgotten about when performing regular maintenance. The job of creating a spark in the combustion chambers that ignites the air/fuel mixture in the engine is your GMC K25 spark plug. Basic spark plugs use a copper electrode, while performance spark plugs use platinum or iridium on all current models. When one of the spark plugs does not fire when it should, the engine in your GMC K25 will not turn as hard; reducing power and gas mileage while increasing harmful emissions.
