I recently purchased a stock 1978 FJ40 with an OEM 2F engine. I want to tune it up and put some new spark plugs in it. What do most of you guys with stock 2F engines run in your rig? Thank you very much.

I run these: Spark Plugs are NOT the same, pulstar spark plugs change the game
They gave me 150 extra horspower and my miliage went up to 32 mpg in the city.
Oh yeah, the best feature is they roll your speedometer back as you drive, renewing you engine in the process....
