Someone at a pool hall asked me if I changed my spark plugs to the hotter range. He said he uses NGK BKR5 instead of 6. He says it does add a little power. Personally I think there is no such thing as a spark plug that can add power. But I do believe in efficiency. I also read at the 2gnt site about changing to the hotter range. Anyone done this? Should I do this? As long as it won't damage the motor in any way, I'm up for doing it.

It's not going to hurt anything. I ran them for 6+ months before i turbocharged my car. There's quite a few other here than are running them. A spark plug, unless it shatters and ruins your valves, would have an extremely hard time damaging a motor.

Yeah, it won't hurt and theoretically in a n/a engine, a hotter plug should provide a more dynamic spark with a thorough burn. However, to be quite honest, like Dino when
I was n/a, I installed that hotter range and really couldn't discern any difference in HP, besides the improvement in responsiveness in your car after every spark plug change.

I got them in my '96 Rs n/a. I havent really noticed any gains in HP, but it does seem to be more efficient than the old normal plugs.

I'm with the above, ran 'em didn't really notice a whole lot. But if your gonna buy plugs with as well get ones that help (even if it is only a little).

i got em, and never changed back to whatever i had before.
i changed em with the magnacore wires, so i was able to notice a difference, although small.

wo0t!
well, this is my dyno just after adding plugs


hehe

Yeah right... 363 hp in a NA eclipse..HAHAHAHAHA

I noticed a small increase as well, I would do it again, I say go for it

whoa 400 HP from just adding hotter plugs!!! I'm game :P

I used to have em also, hehe when its time to change em get some.
