CPS & spark plug advice please
1) Is the Bosch P/N 0 261 210 170 from GermanAutoSupply on ebay correct? It is listed as OK for 2004 SLK320 but not for 2004 Crossfire. I want to keep a spare in the car for long roadtrips.
2) What spark plugs do you all recommend for the longest life? I have always kind of stuck with Autolite for American cars / Bosch for German / NGK for Japanese. Is there a specific Bosch plug you guys like? I am more concerned with life than trying to save a few bucks.
Thanks!
