Re: What size spark plug socket to buy

My preferred spark plug for the Camry would be the NGK Iridium-IX, BKR6EIX-11 (or for a couple bucks more the Laser-Iridium with a platinum ground pad). If you want cheaper plugs, go with G-Power BKR6EGP but I wouldn't go cheaper than that. (For the 7A-FE 1.8L Corolla engine, consider BKR5EIX or BKR5EGP). Check

for prices and shipping cost.

The fact that the second letter is K (for both plugs) means that it uses a 5/8" construction and you will need a 5/8" spark plug socket, such as:

$3.99 5/8" socket, 3/8" drive (this is what I use):

or you can get a $9.99 set of 4 sizes:

Read the spark plug code chart at:

B =3D 14 mm threaded diameter*** K =3D 5/8" construction R =3D resistor 6 =3D heat range E =3D 1.5mm center electrode insulator IX =3D Iridium IX -11 =3D pre-gapped at the factory to 1.1mm (absolutely no re-gapping an Iridium)

You need to follow torque specification in the REPAIR MANUAL, not necessarily the generic instruction on the NGK site, which says 18-21 lb/ft. Why? Because these are dry values. The manuals tells you to dab

*a little* spark plug anti-seize (2-3 threads AWAY from the tip end) and torque to 13 lb/ft. Since anti-seize lowers torque required, so 13 lb/ft is what you use, not 18. Otherwise you over torque and may strip the threads in the cylinder head (read: $$$$$).

Generic spark plug installation instruction:

Spark plug antiseize, about $1.25 for each one-use pouch. (A tube is cheaper.)
