I need to replace the spark plugs on my recently acquired 1990 300E 3.0L. I have heard that platinum plugs are NOT recommend for the 300E. Any truth? What # Bosch plugs do most people use?
Also i checked into the rotor and distributor cap at my local NAPA store and the price seemed unreal?! The quote was $90 for the cap and $33 for the rotor. Those prices were based on a discount IF I qualified. Are those prices pretty common for those plastic parts? What brands seem to work best?
