The torque specification for the spark plugs on a Toyota Supra varies depending on the specific model and engine. However, based on the search results, it appears that the torque specification for most Toyota Supra spark plugs is 13 ft-lbs (foot-pounds) or 18 N-m (Newton-meters).
It is important to note that using a torque wrench is recommended to ensure proper tightening of the spark plugs. Finger tight or hand tightening is not reliable for determining seal contact. Additionally, it is advisable to use a properly calibrated torque wrench to avoid damaging the head threads or under-tightening the spark plugs.
Please refer to the specific service manual or owner’s manual for your Toyota Supra model to confirm the exact torque specification for your vehicle.

Should you put anti seize on spark plugs?
Thread breakage can sometimes involve removing the cylinder head for repair. Metal shell stretch changes the heat rating of the spark plug and can result in serious engine damage caused by pre-ignition. Do not use anti-seize or lubricant on NGK spark plugs. It is completely unnecessary and can be detrimental.
What is the correct torque for spark plugs?
Recommended Torque and Tightening Angle
| Thread Size | Applicable Models | Recommended Torque |
|---|---|---|
| M10 | Stainless Gasket Type ( *1 ) | 10-15N・m |
| M12 | All Types | 15-20N・m |
| M14 | Types other than the ones shown below | 20-30N・m |
What is the torque on a Toyota Supra?

Is hand tight enough for spark plugs?
If your using plugs without a gasket ring (the shamfered type) then hand tight plus a quarter turn – no more. If it does have the gasket ring (looks like a metal washer) and the plugs are new then hand tight plus half a turn. If the plugs are old then hand tight plus a quarter turn.
Is a tighter or looser spark plug gap better?
If you are too tight on your gap you may fail to ignite the fuel, or produce a sufficient flame front to have complete ignition. If your gap is too wide your coil may not have enough juice to jump the spark. So the plug has a gap setting recommended for your bike or car. This is where it is supposed to be set at.
What is the torque of the Supra?
・A 3.0 liter twin-scroll turbo engine continues the Supra straight-6 legacy. Producing maximum torque of 500 Nm at just 1,600 rpm, this power plant enables drivers to savor acceleration that responds directly to gas pedal control.
Can over torquing spark plugs cause misfire?
Careful hand installation and the use of a torque wrench is always recommended by spark plug manufacturers because over and under torquing can easily create a misfire situation.
How tight should I put my spark plugs?
Screw in the plug until it “seats,” that is, it’s finger tight. Turn the plug an additional ¼ turn. If you’re installing a new plug, screw in the plug until it seats, then turn it an additional 2/3-3/4 turn. This crushes the washer between the plug and the head, forming a tight seal.
