I was just curious since I am running a GIAC CHIP/TEST PIPE/CATBACK EXHAUST.

Is it safe to use these on my car?

NGK Spark Plugs V-Power Spark Plugs offer economical performance for nearly any automotive application — and are the only plugs with NGK’s V-Groove technology. They enhance ignitability, lower the voltage requirement of ignition systems, and have strong anti-fouling characteristics, while improving fuel mileage and acceleration performance. The V-Power plugs also are highly durable against electrical and chemical wear, making them a long-life replacement plug. Because of the V-Groove, the spark occurs at the edge of the center electrode. So heat is not absorbed by the electrode itself (“quenching effect�). This allows the flame kernel to expand quickly and efficiently for a complete burn and great performance.

 

7E are more for big turbo setups

 

I am running BKR7E's gapped to .028 and they are working fine. Also, when i pulled the old ones they were the Bosch dual electrode ones just like the first picture you posted, and it ran good with those in too.
