Introduction ------------ [Go to step 1](https://www.ifixit.com/Guide/How+To+Replace+the+Spark+Plugs+In+Your+2018%E2%80%932024+Toyota+Camry/185986) This guide shows how to replace the spark plugs in your 2018-2024 Toyota Camry equipped with the 2.5L 4-cylinder engine. The spark plugs provide the means for an electrical spark to ignite the fuel-air mixture in your engine. Because they are precisely matched to your engine, using the correct plugs (with the correct overall size and "gap") is important for proper operation. Failing, fouled, or incorrectly-gapped spark plugs can cause misfiring, increased emissions, poor fuel economy, and ignition‑related trouble codes. **Note:** The engine should be warmed up fully, and then allowed to cool down for 1-2 hours before performing this replacement.

[**Step 2** Remove engine cover](https://www.ifixit.com/Guide/How+To+Replace+the+Spark+Plugs+In+Your+2018%E2%80%932024+Toyota+Camry/185986#s394904) --------------------------------------------------------------------------------------------------------------------------------------------------- Skip to this step [Edit](https://www.ifixit.com/Guide/edit/185986/394904) * Pull the plastic engine cover upward at its three retaining tabs and lift it off the engine. * Store the cover safely; it dampens direct‑injection pump noise and must be reinstalled.

[**Step 3** Disconnect and remove ignition coils](https://www.ifixit.com/Guide/How+To+Replace+the+Spark+Plugs+In+Your+2018%E2%80%932024+Toyota+Camry/185986#s394905) -------------------------------------------------------------------------------------------------------------------------------------------------------------------- Skip to this step [Edit](https://www.ifixit.com/Guide/edit/185986/394905) * Press the release tabs and unplug the four ignition‑coil connectors. * Remove the four 8 mm bolts that secure the coils to the plastic valve cover. * Lift each coil straight up, ensuring the rubber weather seal comes out with the coil. * The coils are identical, so their positions do not need to be noted. * Handle the three‑wire coils carefully; they differ from older four‑wire Toyota coils.
