By Brett Foote - October 30, 2014

This article applies to the Ford F-150 (2004-2014) and F-250, F-350 Super Duty (2005-2014).

Spark plugs are something that you don't have to replace very often, but they play a big role in how your F-150 or Super Duty performs every day. On any kind of plugs, sparks like to jump from the sharpest point on the center electrode to the sharpest point on the side electrode. Plugs that retain a sharp edge for a longer period of time are typically made out of platinum or iridium, because these materials are harder than copper and have lower melting temperatures. This is part of the reason why platinum and iridium have become a popular choice among buyers. For a little extra money, you can buy a set of plugs that will perform better and last longer. The average copper spark plugs last from 10,000 to 20,000 miles, while the more expensive iridium or platinum can last 60,000 to 120,000 miles.

Champion plugs are often cheaper than the rest of our competitors, depending on which material you select. Most Champion plugs can be owned for $2-$4 each. Though the company itself has been in business for over 100 years, they don't have a great reputation among forums. Many buyers have reported having problems with failed plugs after only a few thousand miles, though others had better luck. It seems to be a roll of the dice, one that isn't really worth saving a little money up front for. Recommended if you are looking for affordable plugs.
