Corolla Spark Plug Change How To
- 4x Spark Plugs (Denso IK16TT)
- 10mm wrench
- 3/8th wrench, spark plug tool (5/8th), extension tool
There is a 10mm bolt holding down each spark plug connector. You can disconnect the connectors and unbolt each connector. I disconnected the entire rail and left the connectors on, but for this next picture I show how it appears with one disconnected.
With the connectors off, you can use the extension & 5/8ths spark plug grabber to swap each one out
Then button it up and it’s good to go!
