    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.
    Cold Air Intake, Muffler Delete, Vinci High Performance Dual Valve Springs, Hardened Pushrods, Yella Terra 1.85 Rockers, Some Hydropdipped Stuff, Strut Tower Brace, Some SS Badges, boost/vacuum gauge, fuel pressure gauge, some checkered stripes, drilled/slotted rotors, ZL1addons Stealth wickerbill, Ruxifey LED side markers

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