I've got 4 plugs for my '80 RX-7 race car, and I've never seen these kindsa plugs before.. they're 4-prong NGK plugs, how do I gap these things?

 

you don't

 

i also just got some 4prong ngks. and i was wondering the same thing . . . they are good straight from the box?

 

All NGK plugs come pre-gapped!. and you cant gap the 4 prong plugs!.

 

If you can't figure out how to do it, ask the guys on the forum... If they can't figure out how to do it... Guess what.

It can't be done.

Funny thing to do is go to the parts counter guy and say, "I don't have a gapper. Can you set these to a .035" gap please?" and hand him the box of plugs. Watch the expression when he pulls one out.

Same thing happens when you ask for a timing belt for an RX-7 or a water pump or radiator for a 1973 Volkswagen Beetle.

 

NGK BR7EQ-14
The 14 refers the gap (.055")

 

Or a 83 corvette, or how bout a 92 Rx-7?
