A few quick questions.... What spark plugs would you recomend for a 1996 "mid-facelift" W202 Esprit ?(i.e. some facelift features, but mostly pre-facelift). Is there a difference in spark plugs between the pre and post facelift? (i.e. should I be looking for specific plugs, or any plugs for a W202?) Are the NGK Iridium "the best" (subjective, I know) there are, or is there something better? Is there a difference between NGK Iridium and NGK Trade? Essentially, I need the plugs to be 110% reliable, not to seize in the desert when I may need to pull them out to dry out the cylinders (we are crossing a few streams futher South), and to be as efficient as possible (it is a rally after all!) Finally, I'm going to change the leads while I'm at it... should I got for OEM, Bosch or something else? I've seen some advertised as "high performace" silicone coated ones, but I'm suspicious... again, reliability is the main concern, with performance coming a close second TIA! M.
