Sparkplug Torque

I have a 2005 Camry LE 4 cylinder 2AZ-FE engine that I am replacing the sparkplugs in. Dose anyone know the torque specification for the plugs?

Well I checked some other sources and came up with the following. Called the local Toyota dealership and asked a service writer he checked with one of the mechanics and they said “about 14 foot pounds”. I wonder if he uses a torque wrench or just his calibrated arm when doing customers’ cars. I checked two sparkplug manufactures specs (Denso and NGK) and they both said 18 – 21 fp. Then I checked with a local independent mechanic and friend and he said that he was await that the manufactures call for a higher torque but thought that 18 fp would be the max with the aluminum heads. He goes to 16 fp. So, that is my compromise I used 16 fp on my car.
Changing the spark plugs is very easy on this car and took me about 15 – 20 minutes. I used a ¼ drive #10 socket with ratchet wrench to take the 2 engine cover cap nuts off then pull the cover straight up and off. Disconnect all 4 electrical connectors from the combination coils / spark plug leads. These have a quick disconnect connector that you push down on the retainer clip and wiggle the connector louse. DO NOT pull or wiggle on the wires attached to the connector. Set all 4 of the connectors and associated wires to the rear of the engine out of the way. Then ONE at a time using the same #10 socket and ratchet combo unscrew the hold-down bolt on top of the combination coils / spark plug lead then with a twisting motion pull the assembly up and out of the hole. In the hole is your spark plug. Look down the hole if there is any debris, dust, dirt you need to blow it out with compressed air BEFORE you remove the plug. If you don’t it might end up in your engine. Mine were very clean the gaskets on the base of the combination coils / spark plug leads had done their jobs and kept crud out. Using a 5/8 sparkplug socket ¾ drive with a 10 inch extension and ratchet wrench remove the plug. NEVER try to use a regular socket it must be a special sparkplug socket with the rubber insert or you will damage your plugs. Additionally, I tape the socket to the extension so it comes off the plug together when installing the new one. The sparkplugs this engine use are iridium and you DO NOT re-gap them. The come pre-gaped from the factory. Screw the new plug in the hole by hand with the socket and extension then torque to what you believe is correct I used 16 foot pounds. Reinstall the combination coils / spark plug lead and do the other three plugs one at a time. Snap the convectors back on the combination coils / spark plug leads and reinstall the engine cover. See, easy.
