Yo: Just replaced the plugs with Bosch Platinums. The ones I took out are the Supers with the same part number listed in my Bentley. Any harm or foul? The Platinums are the ones with the part # match for my car, per my local auto joint. TIA Todd a/k/a The Judge '90 80Q (With the right plugs?) '86 16v Scirocco (Wolfgsburg Ed.)
