Reviews of NGK spark plug

I just did mine not too long ago and bought the NGK's @ Advanced but they claimed that it had to be gapped @ 0.032 but when I took the old ones out, the bosch we gapped @ 0.030. I put the new ones in and you can feel it not running as smooth but I've been too lazy to find some gapped @ 0.030.

I changed over to the BKR7E model to see how they worked. I wasn't impressed because after that the RPMs on my tach wouldn't stay steady at idle.

My old GLX didn't like anything but NGK coppers.

i have run the ngk v-power plugs the past couple of years with great results. part number r5671a-9

If you like Bosch plugs, use a 7 heat range. The stock 8 is fine for quick in-town trips at stock <10:1 compression. Older 8v's used 7 with the same combustion chamber and lower compression, with 0.032" gap stock. At 11:1 with a big cam and the same ignition mods, an NGK tech told me to run colder plugs (Bosch 6 equivalent, NGK 7) at 0.035" gap. He sent me a box of NGK race plugs, I gapped them, and my car ran sooooo much nicer. I was using Bosch W7DC and W7DTC (even worse) before.

so right now I'm using ngk bkr7e for a turbo application. i am pretty happy with them.

I would also recommend NGK plugs, they are made in Japan and well worth the money.

I made the switch to NGK over a year ago, and haven't looked back. NGK are all made in Japan, and they're more consistent. Multi-electrode plugs hold too much heat around the center electrode, which increases the probability of detonation. Gapping the plugs is also much tougher to do. The grounds can also hold more garbage and shroud the spark.

That being said I ran Revo stage 1 and now APR stage 1 and in both cases I've had no issues running the NGK BKR7EIX plugs. I inspect them at a reasonable interval to make sure combustion looks good with them and it appears that they are doing just fine.

21K on my NGK's and no problem. Yes they were plug and play.
