I've had several mechanics tell me I have had the wrong spark plugs in my car. I suspect there is some book or computer that has it listed wrong. I don't know whether it is my current mechanic's or one that I no longer see because he tried to rip me off. I wanted to find out what kind of spark plugs it ACTUALLY uses. I have a '95 Beretta, 4 cylinder.

Any help is appreciated.

Call the dealership and a couple of different parts stores and see what they tell you.
