2003-2008 Toyota Corolla Spark Plugs How-To

Corolla Spark Plug Change How To

Requires:

  • 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.

Connectors 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!
