The original OEM spark plugs in this 2018 Camry were the **[Denso FC16HR-Q8](https://amzn.to/2VweaL6)**. The tools needed to complete this procedure include an 8mm socket with a 1/4" drive ratchet, a **[14mm spark plug socket](https://amzn.to/42MGjAL)**, (or a 9/16" spark plug socket), an extension bar, a 3/8" drive ratchet and a tube of **[dielectric grease](https://amzn.to/2VwAkgh)**.

Set the engine cover aside in a safe place. Clean off the top of the engine with a wet/dry shop vacuum or compressed air to help prevent from having debris fall down into the spark plug well. Push in the release tab on the electrical connector before sliding it straight out of the ignition coil housing. **[ Disconnect Power Plug](https://www.paulstravelpictures.com/2018-2022-Toyota-Camry-Spark-Plugs-Replacement-Guide/2018-2022-Toyota-Camry-Spark-Plugs-Replacement-Guide-007.html)****[ Loosen Counterclockwise](https://www.paulstravelpictures.com/2018-2022-Toyota-Camry-Spark-Plugs-Replacement-Guide/2018-2022-Toyota-Camry-Spark-Plugs-Replacement-Guide-008.html)****[ Single Bolt Removed](https://www.paulstravelpictures.com/2018-2022-Toyota-Camry-Spark-Plugs-Replacement-Guide/2018-2022-Toyota-Camry-Spark-Plugs-Replacement-Guide-009.html)** Loosen the single bolt that secures the ignition coil to the top of the engine by turning it in the counterclockwise direction with an 8mm socket and a 1/4" drive ratchet. Set the bolt aside in a safe place. **[ Rotate Back & Forth](https://www.paulstravelpictures.com/2018-2022-Toyota-Camry-Spark-Plugs-Replacement-Guide/2018-2022-Toyota-Camry-Spark-Plugs-Replacement-Guide-010.html)****[ Ignition Coil Removed](https://www.paulstravelpictures.com/2018-2022-Toyota-Camry-Spark-Plugs-Replacement-Guide/2018-2022-Toyota-Camry-Spark-Plugs-Replacement-Guide-011.html)****[ Toyota 90919-A2009](https://www.paulstravelpictures.com/2018-2022-Toyota-Camry-Spark-Plugs-Replacement-Guide/2018-2022-Toyota-Camry-Spark-Plugs-Replacement-Guide-012.html)** Rotate the ignition coil back and forth a few times to make sure the rubber dust boot is not stuck or "frozen" to the top of the old spark plug. Pull the ignition coil straight out of the spark plug well. (If you need to replace a faulty ignition coil, the part number is **[Toyota 90919-A2009](https://amzn.to/2sdg8m8)**. If you have an OBDII / OBD2 code scanner, you may see code P0354 which indicates a problem with the coils.) Set the ignition coil aside in a safe place. I recommend only checking or changing one spark plug at a time to help further reduce the risk of having debris fall down into the cylinders. **[ Spark Plug Well](https://www.paulstravelpictures.com/2018-2022-Toyota-Camry-Spark-Plugs-Replacement-Guide/2018-2022-Toyota-Camry-Spark-Plugs-Replacement-Guide-013.html)****[ Spark Plug Socket](https://www.paulstravelpictures.com/2018-2022-Toyota-Camry-Spark-Plugs-Replacement-Guide/2018-2022-Toyota-Camry-Spark-Plugs-Replacement-Guide-014.html)****[ Loosen Counterclockwise](https://www.paulstravelpictures.com/2018-2022-Toyota-Camry-Spark-Plugs-Replacement-Guide/2018-2022-Toyota-Camry-Spark-Plugs-Replacement-Guide-015.html)** Attach the **[14mm spark plug socket](https://amzn.to/42MGjAL)** to the extension bar and a 3/8" drive ratchet. Lower the socket into the well and push it securely over the old spark plug. Carefully loosen the old spark plug by turning it in the counterclockwise direction.

Spin out the old spark plug the rest of the way by hand. Lift the extension bar and socket out of the well. Detach the old spark plug from the socket. The Camry service manual specifies that the OEM iridium tipped spark plugs should last up to 120,000 miles. The original spark plugs in this 2018 Camry were part number **[Denso FC16HR-Q8](https://amzn.to/2VweaL6)**. **[ Spin In New Spark Plug](https://www.paulstravelpictures.com/2018-2022-Toyota-Camry-Spark-Plugs-Replacement-Guide/2018-2022-Toyota-Camry-Spark-Plugs-Replacement-Guide-019.html)****[ Tighten Clockwise](https://www.paulstravelpictures.com/2018-2022-Toyota-Camry-Spark-Plugs-Replacement-Guide/2018-2022-Toyota-Camry-Spark-Plugs-Replacement-Guide-020.html)****[ Apply Dielectric Grease](https://www.paulstravelpictures.com/2018-2022-Toyota-Camry-Spark-Plugs-Replacement-Guide/2018-2022-Toyota-Camry-Spark-Plugs-Replacement-Guide-021.html)** Push the new spark plug into the socket. Your socket should have a rubber insert or a strong magnet to securely hold the spark plug in place. Gently lower the new spark plug down into the well. Spin in the new spark plug a few turns by hand in the clockwise direction to help prevent from having it become cross threaded. Tighten the new spark plugs to about 1/4 turn past finger tight. They should be snug but do NOT over tighten them. If you insist on using a torque wrench, the service manual specification for most Toyota vehicles lists **13 lb-ft**. Some spark plug manufacturers specify 18 lb-ft of torque. Check your spark plug product box for details. Apply a small amount of **[dielectric grease](https://amzn.to/2SzpLY0)** to the opening in the rubber dust boot at the bottom of the ignition coil. The dielectric grease will help keep out any debris or moisture to ensure a reliable electrical connection. **[ Lower In Ignition Coil](https://www.paulstravelpictures.com/2018-2022-Toyota-Camry-Spark-Plugs-Replacement-Guide/2018-2022-Toyota-Camry-Spark-Plugs-Replacement-Guide-022.html)****[ Spin In Single Bolt](https://www.paulstravelpictures.com/2018-2022-Toyota-Camry-Spark-Plugs-Replacement-Guide/2018-2022-Toyota-Camry-Spark-Plugs-Replacement-Guide-023.html)****[ Tighten Bolt Clockwise](https://www.paulstravelpictures.com/2018-2022-Toyota-Camry-Spark-Plugs-Replacement-Guide/2018-2022-Toyota-Camry-Spark-Plugs-Replacement-Guide-024.html)** Lower the ignition coil down into the spark plug well. Push on the ignition coil until you feel the rubber dust boot securely attach to the top of the new spark plug. Rotate the ignition coil back and forth a few times to make sure the dielectric grease is evenly spread out. Line up the bolt hole in the ignition coil with the corresponding hole in the top of the engine. Spin in the bolt a few turns by hand in the clockwise direction to help prevent from having it become cross threaded. Continue tightening the bolt with the 8mm socket and a 1/4" drive ratchet until it is snug. Try to avoid over tightening the bolt to prevent from cracking the plastic ignition coil housing. **[ Push In Power Plug](https://www.paulstravelpictures.com/2018-2022-Toyota-Camry-Spark-Plugs-Replacement-Guide/2018-2022-Toyota-Camry-Spark-Plugs-Replacement-Guide-025.html)****[ Replace Engine Cover](https://www.paulstravelpictures.com/2018-2022-Toyota-Camry-Spark-Plugs-Replacement-Guide/2018-2022-Toyota-Camry-Spark-Plugs-Replacement-Guide-026.html)****[ Spark Plugs Replaced](https://www.paulstravelpictures.com/2018-2022-Toyota-Camry-Spark-Plugs-Replacement-Guide/2018-2022-Toyota-Camry-Spark-Plugs-Replacement-Guide-027.html)** Push the electrical connector straight into its socket on the ignition coil. You should feel or hear the power plug "click" securely into place. Push the foam rubber engine cover back down into place. Start the engine and listen closely for any strange sounds which might indicate a loose spark plug or a disconnected power plug. Be sure to record the spark plug change in your vehicle's service records.
