2005-2008 Mustang Motorcraft SP-547 Spark Plugs - Platinum
The factory Motorcraft spark plugs are designed to last a very long time, but eventually, they can start to get worn. Worn spark plugs can cause misfires, detonations, and poor gas mileage. Replace those old plugs with new Motorcraft replacements. These plugs will get your engine running back to tip-top shape! Motorcraft copper core spark plugs are designed to superbly conduct electricity and be durable enough to withstand everyday use!
