I'm changing my plugs to the ht0's for my new nitrous tune but I have a question about them. I read something about having to gap spark plugs but I have no idea what that is. Do I have to do something to them before I can install them? Or is it a simple process of removing the old ones and putting these ones in their place? I bought the plugsfrom brenspeed if that matters. Thanks in advance.

Gapping is absolutely necessary. Here is the link to a video that will show you how to do it.

Check the specs from the plug manufacturer for your car. I know for Champion, its .044 or .045. It may be the same for your plugs.

Brenspeed may have pregapped them for you. Don't think you are going to just tap them on a table top like that video shows. It's not that easy to gap these plugs.

zex recomends .030 to .035
i got mine from brenspeed and seth said they didnt need to be gapped but checked the gap anyway and the were right in spec with what zex recomends
you cant use a traditinal gapper because its not like the factory plugs the hto's have abridge that goes over the tip that gives the spark, so you need a special plug gapper for that type of plug
