Unless your going to run a lot of RPM or forced induction, then stock is fine. You can use aftermarket if you wish, IMO some of the brands are high quality and cost less. I wouldn't spend the extra on the coil and module unless they have failed. Is the cap and rotor very worn? I have Delco plugs in mine, FR5LS if I remember right. I used the Taylor wires and reused the stock looms. I would buy new looms next time.

Well I need plugs wires cap and rotor. What happend is i got mosture in the cap and it caused major misfires. i dried it out, and drive it, then it start to mis again. I took my cap off that thing look really bad burnt up. So i think my coil and module are going bad. Do you know how to test them??? what the specs are??? please. I want to replace everything in one shot. but if the coil and module test good then no need to replace them

There's a procedure in any Haynes manual on how to test them, you'll need a digital multimeter. It has illustrations that are quite helpful.
As far as replacement stuff, you only need the OE parts, none of the expensive stuff will make a difference.
I splurge on wires myself though, MSD 8.5mm Superconductors.
