Help needed... placing an order; NGK plug gapping?

[fuelonempty]

I bout to buy a couple sets of the TR7's... What should I gap them at? Or do I need to gap them at all?

Mods in Sig...

You'll have to gap em but to what spec will depend on your numbers....HP/boost

TR7ix you mean. Pretty sure they discontinued the TR7's a long time ago. If they are the iridium you might be able to gap the a little less than a standard plug since they burn hotter.

Even if the manufacturer says they are "gapped" it is always a good idea to check and regap if necessary.

never been on a dyno.. about 20 lbs from the 3.4...

they are the TR7IX iridium plugs, I just want to double check what the gapping should be.

They are the same plugs DMP put in my motor when it was built.

I would ask Stan what he suggests to gap them at. But either way, I check each plug as it is possible the gap could be altered during shipping. It's easy peace of mind.

you don't gap Iridium plugs! They cone pre gapped.

pre gapped, to what spec... as in safe for the boost i'm running?
