I haven’t come across a detailed guide for replacing spark plugs on the 2TR engine, and my first attempt was a learning experience. So, I’ve decided to create one for everyone here.
Here’s what you’ll need:
- 10mm socket
- 1/4" drive ratchet
- Extension
- 9/16" spark plug socket
- Philips head screwdriver
- Flat head screwdriver
- New spark plugs (I used NGK Laser Iridiums)
- Anti-seize (highly recommended to prevent thread issues in the future)
