Guide: replace spark plugs on a Toyota 2GR-FE
Tools and supplies required
- torque wrench (capable of 15 ft lbs)
- 5/8” spark plug socket
- 6” socket extension
- 10 mm wrench
- (optional) ignition coils (Denso 673-1309)
- spark plugs (Denso 3426 FK20HR-11 Iridium Long Life)
- dielectric greese
Instructions
The above instructions are sufficient, but here are some useful tips:
- Older spark plugs styles require anti-seize. I easily removed an old set of the FK29HR-11s from a cold engine (oops) without anti-seize.
- These spark plugs also come pre-gapped to the correct dimensions.
