Yes, others may disagree......but I would only use the OEM denso plugs.

Agreed, agreed, and agreed.
If price is the issue (and it seems it is) go to www.toyotapartsales.com (aka Trdparts4u.com) and order the parts.
However, using double vs. single prong plugs is NOT going to net you much if any HP gain. If you are having issues with your engine, figure out what the problem is FIRST them go from there. The spark plugs are rarely the problem.

I cant imagine that money is the problem. I just got Denso plugs from the dealer for about 3 bucks a pop. The wires on the other hand cost about 50 bucks.

It is better to spend a little more and have piece of mind, if that is all it comes down to. I paid $2.33 ea at a local auto parts store. Denso dual grounds. Do not gap!

You can use either dual or single electrode. It is unlikely you will notice any difference between the two, other than longer life with the dual electrodes.
I've run both and for the few extra bucks, the duals are worthwhile since you won't need to change them as often.

I put a set of AC Delco singles in my 4Runner 10k miles ago and it runs fine. I wanted the originals but they weren't readily available around here at the time. I'm sure that Toyota wants you to use the doubles for a reason. What I honestly believe is that the doubles have a longer service life and Toyota recommends them to comply with their service schedule.

Several years ago, I put in some single ground plugs (densos even) and ran them for about a year. Even though it was running ok, I noticed a little power loss so I decided to check the plugs and 4 out of the 6 were carmel colored - all the way to the top of the porcelain was brown. I wish I had some pics, because they were fried! I've been running dual ground NGKs for years now and no discoloration or power loss ever again. Maybe some 3.4s aren't as picky as others, and some might run fine on single grounds for a while, but 1 thing is for sure: All 3.4s will run better with duals.
