Review on Bosch Automotive (FR7NPP332) OE Fine Wire Double Platinum Spark Plug - Single: Enhance Your Vehicle's Performance! by Richard Kuntz

Bought a 2010 E93 with 71,000 miles on the odometer. The car jerked or jerks when accelerating sharply or driving uphill. congestion suspected. Spark plugs changed at 72,000 km, the original Ngk with the BMW logo was still there, I removed them. I never thought automakers would push 100,000 units. The candles looked like garbage. Now a little smoother when idling, under the hardest acceleration or load, no problem. I also replaced the coils, but the problem turned out to be in the candles. For two weeks only, any questions I will update. At the moment the engine runs like butter. Update, two years later in October 2020 the car is about to hit 78,000, yes just 6,000 miles. Still no problem.
