Follow these steps carefully
Spark plugs are threaded into an aluminum head, so always start with a fully cold engine to avoid stripping threads and getting burned. Park on level ground, set the parking brake, and prop the hood open.
Grab the plastic 2AR-FE engine cover and pull it straight up. It is held by rubber grommets, no bolts. Set it aside.
There is one coil-on-plug ignition coil per cylinder. Press the small release clip on each electrical connector and pull it free. Do all four before touching bolts.
Using a 10mm socket, remove the single retaining bolt from each coil, then twist gently and pull each coil straight out of its well. If a coil boot is stuck, twist more rather than yanking.
Use compressed air or a shop vacuum to clear dirt and grit from around each spark plug before removal. Debris falling into an open cylinder is the classic cause of a ruined job.
With a 16mm (5/8 inch) spark plug socket and an extension, break each plug loose and unscrew it by hand once free. Note the condition of the old plugs: oil-fouled plugs on the 2.5L 2AR-FE can point to the oil-consumption issue these engines are known for.
New iridium plugs come pre-gapped at 0.044 in (1.1 mm). Do not re-gap them. Thread each plug in BY HAND until it seats, then tighten with a torque wrench to 13 ft-lb. Hand-starting is what prevents cross-threading the aluminum head.
Push each coil back onto its plug until it seats, reinstall the 10mm retaining bolts and snug to 5 ft-lb, then reconnect each electrical connector until the clip clicks. Work one cylinder at a time if you want to guarantee nothing gets mixed up.
Press the engine cover back onto its grommets. Start the engine and let it idle for a couple of minutes. It should idle smooth and quiet with no check engine light. If a misfire code like P0300 appears, recheck that every coil connector is fully seated.
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
