Yes, when it happened i thank this... but the car was running perfectly with this gaps over 12000miles... i will check the sparkplugs and look for another problem, but cant understand that only happens when get 1.2bar :S below runs prefectly. The problem just begins after update the ectune :S I have installed NGK BKR7E-11 and i think that i gapped it to .30 (Sorry for my bad english!)

NO.. 1) if your running that much boost, i'd go to 8s vpowers. 2) why are you gaping so wide.. go to .028 or .025 and see how it runs, your not going to be able to run mid .030's ...if its blowing out at .030 right now.

Go with NGK Vpower 8's first off.. if you need the part number, here

you want to run as wide as a gap as possible, without blowing out the spark, if your blowing it out at .030 @ 1.2bar, which is what it sounds like, your going to need to go lower, i'd start at .025, if its still doing it, go lower. IF it doesn't blow it out, go up from .025..

But the car was running over 20.000kms with the bkr7e-11 and without any problems.. now suddenly have this problem, but i dont know what is the problem... im investigating it.

Just because it ran, doesn't mean it ran well or efficiently .. i'm telling you, go to 8's you'll be happier and gap like i told you.

I'll be honest I use an old worn out gapper and gap every car I tunes plugs down to .018 just to ensure I don't have any ignition miss fires while tuning it. The plugs actually seem to last longer when you gap them this low because they don't start their ignition miss fire issues as soon as if it were to be properly gapped for added power that can be had. In my personal car, 522ish whp pump gas setup, I cook copper 8s, they last one week then I start to get ignition miss fires up top. Copper 9s last a whole lot longer. At least 4x I think that if I go to iridum 8s they might last and get me less of the undesired effects of the heat range 9 plugs. I've yet to try any iridums in my personal cars. See em all the time in customers cars. Its almost like I have to run the idle and partials a little richer with the heat range 9 plug as opposed to the heat range 8. The heat range 8 I get less cracks and pops at idle, partials are a whole lot easier to get smoother, more room for error in how much you can lean on the partials. I've always got my best traps with heat range 9 coppers. I'm not saying put a 9 in your setup, these are just my findings. One thing I have learned for sure is that there is power to be made in colder plugs, gap sizing and projection.

I solved the problem!... i couldnt imagine that can be the spark plugs! if you take a look to the 4 are in good condition, only a brown colour (extra fuel) but without any other rarely thing. I bought 4 new NGK BKE7R-11 and gapped to .030 (70mm) and now can push the gas to end and blowing to 1.4bar again

Other more thing to know. ;D Thanks for comments.

the 4 spark plugs are like this:

What is your opinion guys?

Are you using Octane Booster?

sIrK · Post by **sIrK** » Sat Jun 19, 2010 9:47 am

No, here in spain is 98 octane, but 2 tanks of fuel before remove the spark plugs the gas station woker put 95 instead off 98 and i added octane booster to compensate it. Why do you ask this? may be of the brown colour?

I changed the spark plugs for new ones and gapping to .030 and now problem is solved

thats most likely why the plugs are red, the maganese in the octane booster will cause a red tint.
