I was wondering if anyone has went to a colder range plug after the stage 2 was installed and what the difference if any. I am curently using NGK BKR6Eix

 

ngkbk7re and they are working good i think. i had a bad puff out of black smoke today but i didnt let the car get warm and i revved it so its prob jus my stupid fault. but they work good for the most part gapped to .040. jus so everyone know sour stock plugs are ngks.

 

NGK BR7RE are the plugs im putting in as soon as stage is installed (2 days)

 

whats the difference between

BKR7E

and

BKR6ES

 

BKR7E are 1 step colder

 

oh and the BKR7Eix are the iriduim plugs

 

They definately made a difference for me, not at first because I gapped them the same as the stock plugs (0.035). After regapping them at 0.040, it's running much better. Last Friday around midday, it was about 93 degrees out and my car was sputtering pretty bad, hesitating and almost stalling at lights. With the new plugs (at 0.040) it's been running smooth since.

 

which plug are u running?

 

I re-gapped the stock plugs at .037 just to see if there is a difference and it seems to run a bit better. They were at .040 when they were pulled. Although here it hasn't hit 90 degrees yet.

Now I have stage2 that should be here any day, and I have a set of NGK BKR7E's sitting here for the big day. I think I am going to keep the .037 gap and see how it goes. If it doesn't work out, the .040 gap was my next move.

 

the 6 is the stock range, 7 is one colder

 

what is the the stock gap when you buy the ngk bkr7eix???

 

NGK BKR7E's.

 

Im guessing the heat was too much for the 0.035 gap?? Mine are gapped at 0.035 ready to be put in tmrw. I'll see how she runs.

 

I had the dealership put the NGK's in as they were installing stage II. I told them to gap the plugs at .38 You can go as close as .35 I can't tell if there is any difference due to the plugs but the stage kit is of the hook. I went one step colder with the NGK BKR7E Copper Plugs. The guy who installed the stage kit new all about these plugs and was going to recomend them to me untill he saw me walk in with them.

 

From the package they are gapped @ .30 which was what was called for my car so i just threw em' in. But for u SS S/C guys, you'll have to re-gap em to proper specs.

 

i have the regular NGK 6 spark plugs waiting to be installed with my new pulley what should i gap them at ?

 

HondaXR200cc there is no point in getting the NGK 6 spark plugs if you have a smaller pulley than stock. You want the 7's. Return the 6's for the 7's and gap them at .38 for the most performance and reliability.

 

If your stock what will the 7's do anything better??

Thanks

 

nah they won't help and if u go too cold you can run into problems

 

Its not recomenend to gap the iridium plugs and it says it right on the package

 

so i just have to buy the iridium one and put it in my cars without touching them at all...

 

pretty much, u dont gap iridium plugs.

 

however I would check the gap incase one was dropped for some reason and closed the gap a bit.

 

Im going to ask the mechanic tmrw and see what he says. Hopefully he knows something about FI and spark plugs.

 

So after all is said and done, now that a couple months has passed , Are there any new, or improved plugs out there ? Like any of the Split-Fire/Bosch/Multi-Electrode(or whatever they are called), Maybe somewhere there is simply a list of what has worked for stock,stage 1 , stage 2 and such. This would help , as I have searched "spark plugs and most info is older. Thanks for any help/insight. This forum is just great for us "do it yourselfers" on a budget.
