Use Toyota plugs - DENSO K16TR11 or NGK BKR5EKB-11 Left side Remove air cleaner hose - large hose clamps on each end and some hoses Disconnect connectors from Ignition Coils Remove Ignition Coils with one bolt each - keep in order Clean plug tube with rag Remove plugs (16 mm) Check gap on new plugs - 0.043 in Smear small amount of anti-seize compound on plug threads Insert new plugs using hose on insulator to hand tighten - don't cross-thread Torque to 13 ftlbs Install coils (bolts - torque 69 inlbs) & connectors Install air cleaner hose Other side is easier and same for details Never pull on wires, only boots. You can check the resistance of the plug wires while they're available. Maximum 25 kohms per wire (Guys, it's a 3.4 L V6  )

I followed Brian R. instructions on changing the Spark Plugs this morning. It was a successful and rewarding experience. I new I had a 6 cylinder SUV, but always wondered why I had 3 wires.
Thanks you are a great help.

If you have a weak ignition from a faulty part, some plugs may show this problem more than others I agree! The only problems I have ever seen are combination of marginal ignition components, that’s where it is just barely making it to the electrodes of the plug itself. Temperature ranges of plugs is your biggest concern. Basically that’s how close to the tip of the electrode the porcelain mounts to the wall of the plug. If you run too hot of plug you can experience pre-ignition. It also shortens the life of the plug. Rotor, cap, wires and plugs. New from the dealer will solve all your secondary ignition problems, this V6 is not a HP motor and does not require or will you gain any noticeable improvement with HP components. The plugs do need regular maintenance and for the work and cost I recommend replacing them rather than cleaning filing and re-gapping. Sharp corner edges on both electrodes is important when cleaning re-gapping if you do decide to just clean. I ran a set of "after market" wires and the engine missed and ran rough until I replaced with factory wires! Good Luck Oh careful not to break the porcelain when tightening. Done it.
