My 2.0 EFi engine runs perfectly, but out of curiosity I've checked if it has the right spark plugs and if they are in healthy condition. It turned out that all four spark plugs are for the 1.6, namely Unipart GSP 4562. According to the car manual they should be Unipart GSP 4452. How bad is this? I have only driven a few hundred miles in the car, but the former owner might have driven for years with the GSP 4562 plugs.
My second question: Are there good alternatives for the Unipart GSP 4452?
