Hi,

I was wondering which spark plugs are needed for my car as I want to change them to potentially solve the problem I've been having of erratic idling. My local store gave me a couple of Bosch 510 FR78X Super4 but I am skeptical as to whether these are the correct ones as the audi model for which it is used in is not specified on the packaging. Also, which other spark plugs do people use and which are recommended?

Audi A3 1.6 74kw 8L1 AKL (2000 model)

Thanks for any help.
