I use a gear wrench on the outside of the spark plug socket from the top with the coil packs off.

Use flexhead ratchet and a 3 inch extention and a one inch extention..that combo of tools will change all of them..changing # 8 from under the car works best..I have all the smog stuff off my car and I can change plugs in 25 minutes with out taking off the coil packs... make sure you feel the two clicks on the coil end and the single click on the plug end of the wires when you put them back on..

Bottle of techron in the tank works for most of us. Not sure if you want to remove them and have them sonically cleaned...

Well, just about all engine modification achieve one goal, they cram more oxygen into the cylinder. As you cram more air into the cylinders, then injectors need to flow more fuel to keep the mixture correct. If you keep on modding or so some serious mods like forced induction or nitrous, youll have too much air for the stock injectors to keep up with. Swapping injectors will not gain you anything, but once you get into heavy duty modifications, bigger injectors may be required.

Bad O2 sensors will make your car run rich. Use AC Delco brand sensors and sparkplugs 41-974

AC's are platinum, 55's are copper core. Doesn't platinum last longer?

Look at some plat plugs that have been run for a while lots of time the plat is off the plug..for $1.68 a piece you can't go wrong on a TR 55 NKG ..If your a serious hot rodder you going to look at your plugs from time to time ..they tell ya whats going on in the engine..
