Changing spark plugs on the v8?

[Fanman47]

I did a few searches, but I am unable to find any information on changing the plugs in a V8. How difficult is it? Are there any how to's on this site that you guys can direct me to?

It is done exactly like any other vehicle. Newer ones, like the T4R, have individual coils over each spark plug. Remove the coil bolt and pull up on the coil head and the spark plug booty will follow. Since the head is aluminum then I would suggest using a torque wrench if you are not used to wrenching. 13 ft-lbs is all they take! No need to gap them since the iridium plugs come pre-gapped (like most all plugs today).

I have 108,000 on mine and want to do it before winter.

EZ job.
Be sure to remove air box and inlet tube for access on pass side.
DYI and save $150+

This thread is about the V6 but it's similar enough that it'll help. Follow the links within: http://www.toyota-4runner.org/maint...park-plug-change-instructions.html#post491394
