Befor you even touch anything under your hood. Go buy a Chilton or Haynes Manual for the model and year of your car, this will help you alot. It keeps you from breaking things you dont know much about. Like taking off your rotor... Some people have problems with that.... Somone on here (remains nameless) decided that he needed to break off the plastic guard to remove the set screw that holds on the rotor, instead of turning over the engine so it lines up with the slot in the plastic so you can get a screwdriver in there to remove it...

Get NGK Plugs, and make sure you gap them at the correct gap. Donot buy Platinum. And copper plugs can foul out if you live in an area with high humidity. Also make sure you get the correct heat range.

I have had alot of experience with plug wires, and have had 6 different brands on my D16Z6's. Autolite, Autolite NASCAR, MSD, Mallory, Accel, and OEM. The best I have found for the money, is Accel thundersport 8.5mm and I believe they are 150ohms of resistance per foot? not positive on that tho, they are about $65.00 at schucks, or autozone.

OEM cap, and rotor.

Get a K&N drop in airfilter. Much beter flow, and wont have to ever replace it (just clean every 100k.).
But I clean all of mine every 10k. And replace every 100k. (peace of mind)

Alot of people use Castrol GTX oil, but that is all up to you. Dont go to some shop that will put some no name brand oil in your car, make sure its an oil that is well known. And you should never pay more than 20$ for a shop to change the oil and replace the filter. DONT FORGET TO REPLACE THE FILTER!

Fuel filter is a good thing to replace, and you dont replace it often, OEM is your best bet.
