Poor idle, low fuel efficiency, and engine misfire codes are all symptoms of worn spark plugs. Replace yours with quality factory direct parts to get your engine running as well as possible.
These plugs from BMW are the solution for all of these problems. Over the years, the electrode wears away on spark plugs, causing too large of a gap and weak spark. Additionally, excess carbon can build up and bridge the gap to negatively effect performance. Replace yours with these factory correct units to regain your power, fuel efficiency, and smooth a poor idle.
If you are replacing any aspect of your ignition system, it's best to replace all serviceable components. By doing so, your ignition system will work in better harmony, freeing up hidden horsepower and raising fuel economy. Skim the ECS Tuning ignition area under your model for spark plugs, wires, coil packs and more to get your vehicle into top shape.
