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.
