Thread: The Best Spark Plug Out There

what about these plugs, they really look like side gapped. Anyone know which would fit our cars?
NGK Racing Spark Plugs

Should be the same concept except for $18 more per plug

didn't check the price

Just wanted to comment that I tried some BKR6E and lost some power at the dyno. I was using bkr6e-11 before and got the best result N/A, but I,m going to try the side gapping

That makes sense, BKR6E-11's have a 1.1mm gap (Around 0.039), vs 0.8mm gap (0.032).

With bigger gap, you should see better power and MPG on NA. It would be good on boost too but, the spark would get blown out by boost.

I know this thread is old, but after talking with the guy at advance auto parts, it seem that the ngk bkr7e's arent available anymore. Is anyone else having this problem?

We sat down and tried to cross reference with the denso plugs but couldnt find a match it the proper heat range in copper. So i guess i am kind of screwed unless i want to spend an arm and a leg on iridium plugs, and with how often i like to change my plugs i may have to take out a second mortgage on my house.

Any help in this matter would be greatly appreciated.
Thanks,Jon

Check out this plug. Number is 5820. Non-projected-tip. This keeps the spark plug farther away from detonation shockwaves, and prevents the ceramic from cracking under heavy hot/cold cycles. And they are cheap. Only downside is that they are non-resistor. But I have run them on several cars now without any issues with interference.

Very interesting find Coheed!

What do you mean that they are non-resistor?
