Engine Spark plugs 2 steps colder than stock

Spark plugs 2 steps colder than stock

Can anyone tell me exactly what to look for? I need them by this weekend..

Assuming you wanted to stick with Denso iridium spark plugs: http://www.densoiridium.com/identifyplugs.htm

Take the number from your factory Denso plug and compare it to the chart. A higher number indicates a colder plug.

if u have i/e/h then get ik20 or ik18... if turboed then get ik22

does this plugs need to be gapped or are tehy gapped already and ready to use?

Y would you want a colder plug what will it do (sry i never heard of colder plugs b4)

They should already come gapped properly. As you may have noticed, the engine sticker on the 1ZZFE states "DO NOT GAP" the plugs.

A colder plug dissipates heat away from the tip more rapidly than a hotter plug. This helps prevent pre-detonation. One usually switches to a colder plug when boosting the engine.

I'm not sure if mine came with iridiums -- I have Bosch platinums installed now..
