Best Spark plug for Toyota 4runner
I had this very same problem where on my 07 V6 the acceleration and power was off. I had replaced my spark plugs with NGK Iridium plugs and after dealing with the horrible performance I decided to change them out for OEM platinum (copper) plugs. This made a huge difference and could immediately tell a night and day difference. Regained the torque and power that was missing.
Pros: Regained torque and power
Cons: horrible performance

Toyota 4runner

You can check the forums and it'll say the same thing your asking . It comes down to personal reference ,everyone (including myself ) that I run with in our 3rd gens we run NGK . Just make sure they are dual pronged and gapped correctly and you'll be just fine .
Pros: NGK dual pronged

I wish my Toyota 4Runner spark plug service was that cheap in the Toyota dealer. I was quoted $800 parts + labor for OEM Denso.

Cons: expensive parts and labor
