Everyone has an opinion so here is mine. If you intend to stay with a regular type plug, I like denso better than ngk.

I agree with Jabo that there's a lot of options. There's also a lot of conversation on this topic from a lot of different aspects. Here's the spark plug links from the Popular Mods post:

Plugs last a long time these days. If you learn to "read" your plugs you'll be able to make corrections to problems so you don't simply foul another set of plugs.
