I just did mine today with the Bosch 332's, when I took out the plugs 3 were OEM Bosch (from when the car was new in '08) and 3 were OEM NGK (from a valve cover gasket dealer repair when they replaced 3 plugs and coils). I'm sure both will be fine, but the Bosch were like 8 dollars on Amazon and they seem fine.

Coils
For the coils, it's best to pull one out and see what the OEM was. Online sources kept telling me to buy 55 dollar BMW brand ones but it turns out a 32 dollar BOSCH was the OEM part even though Amazon and other told me it wouldn't fit.

NGK wont have nearly as many misfires if your tuned. they are a step cooler. but they do require you to gap them (.22) they are considered the modded 335i's sparks
