Spark Plug

[Daboss]

Does neone kno anything about these plugs. R they good or bad for a r33 gts-t 1995. I changed my sparks to these yesterday from iridiums and now feels like the car has a loss of power. Can the plugs b the cause or plugs dont affect horsepower drastuically like tht?

5's are too hot, might be OK if you are running sh*t all boost but I would stick to 6's, or if you run a lot of boost (over 1.3 bar) you should probably run 7's...

Did you set the spark plug gap to .8???

Doesnt the manual/book for the brand of sparkies tell what the gap is?

Probably, but if you are running a little more boost that is no longer relevant. If your running stock boost then you could prob get away with 1.1 gap which is what they will most likely come with but running .8 wont cause any issues anyway.

the hotter the plug the hotter the engine gets, and the more chance of pinging you get.

You should get BKR6EGP instead and gap to spec, btw the difference between number 5 plug and 6 plug are 70-100'c. You could be running too hot in your turbo engine.

What gap are you running on your iridium?

Well I dont have anything to measure the gaps with but they look stock to me 1.1mm. Quick Question so wht do the different heat ranges do to or for the car?

The bigger the "number" for NGK, mean the more heat it will cool the combustion chamber.

Try gapping your plug down to 0.8mm.

The gapping tool will look something like this.

I use a feeler (spelling?) gauge to measure the gap of my plugs, then tap the top of the plugs on the wall until the gap is right. Checking the gap after every couple of taps...
