Ignition Parts

I want to replace my plugs, wires, and coils on my 99'Z28. What are the best pieces to use. Thanks for any help in advance.

Stock coils are perfectly fine. If you want to throw money away, I'll PM you my address and you can just send me a check.

Seriously, lots of guys run either NGK TR55 or Iridium plugs and MSD wires. When you swap out the wires, make sure you hear/feel one click on the plugs and two clicks on the coils. Use a little antiseize on the plugs and only install them to 11 lb.ft. of torque.

Thanks man, the car runs fine as is with 75,000mi on it and has all original plugs and wires. Was thinkin it might be a good time to take care of it since its just sittin in the garage for the winter. Theres nothin wrong with the stock coils either so maybe thats a waste of money. So maybe just do the plugs and wires then?

Absolutely. While you are at it change your fuel filter, check your belts and air filter, inspect your PCV hoses, and clean your MAF with some CRC Spray MAF cleaner.

This + fuel filter, bleed breaks and if you have a clutch, bleed it too/A4 change the fluid in the tranny. Also change the fluid out in the rear end. Fluids get old and lose their viscosity which leads to part failure.
