spark plugs
 

I have a 2007 toyota tacoma 4 cyl.4x2 auto. trans. This may sound crazy but, where do I find the spark plugs? And is there any special procedure I need to follow. I have had 4 Tacoma's and this situation is a first.

This shows you where they are located.

This is a complet service manual. It's for an 05 and 06 but should be the same for your 07. There should be a section on replacing the plugs.
