What do your spark plugs look like at 83,000 miles? Replacement guide and tips

## Problem

2017 Lexus RX350 with the new classic Toyota V6 engine 2GR-FKS:
+ 83,000 miles
+ with the factory spark plugs

Toyota recommends 60,000 miles interval for spark plug replacement.

Have to replace them but will start with the plugs in the front, which are easier to remove.
Will also see what the spark plugs look like after 6 years and more than 80 thousand miles.

## Procedure

1. Park your vehicle on a level surface and turn off the engine.
2. Open the hood and remove engine cover.
3. Disconnect the electrical connector from each ignition coil by pressing down on the release tab and pulling it away from the coil.
4. Remove the ignition coil by using a ratchet
* 10mm socket to unscrew the bolts that hold it in place.
* Pull the ignition oil from the tube.
5. Use a spark plug socket to remove the old spark plug from the cylinder head. Turn the socket counterclockwise to loosen and remove it.
6. Check the condition of the old spark plug.
* Wet/oil on the threads of one plug; should monitor possible oil leak of tube o-ring.
* Clean and no carbon deposit, gap still within spec.
7. Compare to the new plugs; they should have the same size and specs.
8. No anti-seize compound on the threads of the new spark plug. The new plugs are pre-gapped so no need to gap them.
9. Use the spark plug socket to thread the new spark plug into the cylinder head. Turn the socket clockwise until the spark plug is snug and seated properly.
10. Use a torque wrench to tighten the spark plug to the specified torque for your vehicle. For the 2GR-FKS engine, the torque specification for spark plugs is 13 lb-ft (18 Nm).
11. Repeat steps for each spark plug that needs to be replaced. We will replace the rear spark plugs in another video.
12. Reinstall the ignition coils by using the ratchet and socket to tighten the bolts that hold them in place.
13. Reconnect the electrical connectors to each ignition coil by pushing them into place until they click.
14. Start the engine to test the new spark plugs.
15. Reinstall engine cover, which makes the engine sound quieter.

## Notes

Again, Toyota recommends 60,000 miles interval for spark plug replacement on this engine another latest models. Spark plugs are cheap so do not delay in their replacement (like me) as worn spark plugs can stress out other more expensive components of the engine such as ignition coils.

Hope this is helpful.

God bless!
