How to 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

• Video instructions
• Step-by-step instructions with pictures

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.
