First, welcome to the forum! <img src="/forums/images/graemlins/cheers.gif" alt="" />

I agree with using Toyota parts, especially the spark plug wires. NGK's and Denso's you can find at NAPA, or maybe one of those other parts places slightly cheaper than your local stealership. Most of the guys here deal with one of the following for Toyota parts or go their local dealer. You might want to check these out.
