clk 430 newbie questions
the car clk 430 with kn filters
what should the oil grade be ? (i was going to buy 5/40 synthetic)
what spark plugs ? (keep standard or is there performance ones)
last of all, how can i avoid any common problems
thanks
#2 Iridium sparkplugs (2) per cylinder
#3 5/40,0/40 synthetic is good.I use Amsoil Euro 5/40 synth!
But like I said new tranny oil fluid chg is numero uno!
