    Tune-up help?

    I am going to do a tune-up to my 98 z-28 6-speed. I have 94k miles on it, and I'm going to start SCCA racing this year. What do you all recommend as a quality and inexpensive replacement. I was thinking about the Bosch +4 plugs...what else should I do?

    Thanks for your help

    just do the normal routine stuff. new plugs, wires, fuel fliter, go with synthetic oils. the +4s are hit and miss.

    Regular NGK TR55 plugs work fine. Fuel filter, transmission service, new diff fluid (and additive), etc.
