120k Service

Hey everybody,

I just hit 120k over the weekend!

I'm planning on buying spark plugs for my V6, and this time, I'm leaning towards Denso. I currently have NGK V-Power's installed, which was done at 90k.

Which Denso's should I get? I'm reading about Iridium spark plugs, but I'm getting mixed messages about them.

I searched this forum, as well as the internet, but I'm most likely not using the correct keywords to find the answer. What does it mean to "torque-to-spec"? How is that done?

Torque to spec just means that you're supposed to use a torque wrench to ensure you're not over, or under, tightening the new plugs. I recently put Denso Iridiums in my V6 and saw a nice bump in gas mileage, granted my engine had factory original plugs at 90k which were way over-gapped by the time they were changed.

Yota, I appreciate it! I'll definitely check out those iridium plugs.
