Follow these steps carefully
Only change plugs on a fully cooled engine. Aluminum heads gall and seize plugs when hot. Disconnect the negative battery terminal with a 10mm wrench before unplugging the ignition coils.
On the 4-cylinder engines (2.4L 2AZ-FE, 2.5L 2AR-FE), pull the plastic engine cover off. It is held by two 10mm nuts. This exposes the four ignition coil packs sitting directly on top of the plugs.
Squeeze the lock tab on each coil electrical connector and disconnect it. These connectors are brittle on a 15+ year-old car, so squeeze the tab, never yank the wire. Remove the single 10mm coil bolt per coil and lift each coil straight out.
Before loosening anything, blast each spark plug well with compressed air (or a shop vacuum). Debris that falls into the cylinder after the plug is out can score the cylinder wall.
Use a 5/8 in (16mm) spark plug socket with an internal rubber insert and a ~6 in extension to remove all four plugs. Inspect the old plugs for oil fouling, which is a known issue on the 2.4L 2AZ-FE that burns oil.
Confirm each new plug's gap is 0.044 in (1.1 mm) with a wire or feeler gauge. Iridium fine-wire plugs come pre-gapped; do not aggressively re-gap them. Do NOT apply anti-seize to the new NGK or Denso plugs. They ship with special shell plating, and anti-seize causes over-torquing that can strip the aluminum head or snap the plug.
Thread each plug in by hand using just the extension to avoid cross-threading. Once seated by hand, torque to 25 N-m (18 ft-lb), the Toyota factory spec for the 2AZ-FE and 2AR-FE. Do not use the old 13 ft-lb internet figure; the service manual spec is 18 ft-lb.
Seat each coil back on its plug, torque the coil bolts to 9.0 N-m (80 in-lb), reconnect the electrical connectors until the tabs click, replace the engine cover, and reconnect the negative battery terminal.
Start the engine and let it idle. It should idle smooth immediately if the old plugs were worn. Take a short test drive and confirm smooth acceleration. If the check engine light comes on, scan for misfire codes (P0300-P0304). Replace all four plugs at once; do not mix old and new.
On the 3.5L V6 (2GR-FE), the front three plugs are done the same way, but the rear bank sits under the intake plenum. The book method removes the windshield cowl and the intake plenum, then replaces the three plenum gaskets and the throttle body gasket while you are in there. Budget 2-3 hours for the V6.
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
