Toyota sounds like great deal if they actually use OEM plug (DENSO iridium). That part alone is \\~$18 each (you need 6).

Pros: great deal, OEM plug

Also check the spark plugs, sometimes people are cheap and buy autolites instead of NGK. Cheap plugs from previous owner give me a headache.

Cons: cheap plugs headache

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

Pros: OEM Denso parts

Cons: expensive parts and labor

Vehicle: Toyota 4runner

I highly recommend avoiding anything other than exactly what is specified in your owners manual, I currently have bad gas mileage because I was too curious to see if the desno two tip would do as good as the other stuff.

Cons: bad gas mileage
