Hi,

I just receive my IK20 and I'm new to the celica world. Should I need to gap them or do they came pre-gap from the factory?



Thanks!

No they are pre-gapped from factory so you shouldn't have to do anything with them.

Thanks !

uh I sell parts all day long and one thing I can tell you is that even though plugs are supposed to be pre-gapped, a-lot of them aren't. In fact I had someone come in and buy some NGK double platinums the other day and he was paranoid enough to check the gaps right there at the counter. Sure enough 5 out of the 6 plugs were wildly out of gap. I attribute this to either factory mistake, shipping collisions, or just being dropped. That is why you should at least check the gaps before you put them into your car. Whats 5 seconds per plug after-all? And If they are out of range then adjust them using a regular gapper unless the plugs are fine-tip iridium, in which case gapping them with a feeler type gapper will ruin the plug. For iridiums you want to use the hook type gapper. So to everyone, ALWAYS check gaps!

Found my thread from way back should be 0.8mm, which engine have you got just to be sure?

I have a 1994 GT. How much gap should they have?
