i know the topic of spark plugs has been done over a few times, i have just replaced mine with Bosch Super 4 plugs. Luvin it. the idle is smoother, power feels better, pulls stronger to red line and economy is better on the freeway by about 10%. i know that they are relatively expencive, retail for about $100 for the set of 8, but i got them at staff discount, 50% off, from my brother.
Have also seen some information on Bosch fuel injectors - {Design III} - American company Fiveo - www.fiveomotorsport.com/Injector_SetsBMW.asp suggesting fuel economy and performance improvements. for $422 for a set of 8.
Has anyone tried them? any results?
