The only option for plug wires is the toyota dealer. Your truck will punish you for anything else. I've always picked up the cap & rotor from them too, but the plug wire are MANDATORY.

They may seem expensive (I think wires, cap & rotor were $50ish all together way back when) but remember that you'll be running them for about 5-6 years, as opposed to maybe a month on AutoZone wires, and a year on the cap & rotor.

For the plugs, Nippondenso (factory) should be available at autozone. NGK also work well. Those are your only two options for plugs that last. If a Toyota comes into your posession with ACDelco, Champion, etc plugs, throw as far as possible and replace with decent replacements. NGKs & Denso's are cheap enough at less than $2/plug that there's no excuse not to run them.

Feel free to replace either of these with whatever you like. I did. Twice. Them I gave up and put quality parts on there. Purred like a kitten, and still does, 5 years later. I still haven't changed anything except the plugs since then.
