NGK BR7EF 3346 Spark Plugs

When upgrading your 1996-2014 4.6L, 5.4L, and 5.8L with boost or nitrous, it is essential to have the correct spark plug. The stock spark plugs are not capable of handling the strain and additional heat caused by adding a high amount of boost or nitrous. The NGK BR7 spark plugs are perfect for Lightning, GT500, Cobra and GT owners looking to have the best spark plug for their supercharged, turbocharged or nitrous vehicles. The non-projected tip design of these spark plugs helps to efficiently dissipate excess cylinder heat associated with high boost large and nitrous systems.
