How to replace spark plugs on a 2008 Toyota Tacoma 4 cyl
Not a difficult job, but difficult to outline without photo/video aid.
Short list, using compressed air, blow out all of the junk that has collected under the intake muffler, then remove the muffler from the throttle body and airbox There are two large hoses, plus two small hoses, one on the rear (crankcase vent) and one in front. There is also a wire harness on the rear that needs to be separated.
Once removed, make sure the top of the cam cover is clean, unplug the wiring harness from the coil packs, remove the bolts (10mm socket), and pull the coil packs from the plugs. The rear plug is a bit of a pain because of the wiring harnesses, but you can carefully separate them and move them out of the way.
The Tacoma 2.7 uses Iridium plugs. Stick with the OEM Denso plugs, don\'t fall for the snake oil salesmen pushing 4 electrode or special "hot spark" designs.
