Question NGKB9EGV's are they safe?????

Are the B9EGV a good plug to use in the turbo engine??
Pulled 2 out of my race bike and put them in.
Had to use more spacers.
Moved the leading plugs to trailers,
I have done this before on N/A rotors.
Is the heat range correct to run all four plugs as B9's?

Yes, you can use EGV's. If your spark plugs has coloration on halfway up the thread, you need colder plugs. If you run high boost and run the car hard, you might need 10's but check the spark plugs first. I run the 10's in the trailings and 9's in leadings.
The plugs sure last longer than the 9EQ's I've been using.

machine down a plug socket so it fits slightly into the housing, DONT use spacers

They are great plugs, you'd have noticed how much smoother and crisper it runs with B9EGV's in it

They are great.
Helped heaps in my starting problems.
Very dare though. Can't you get a long series that is a match to the standard SD????
Any ideas on the code??

For the dude thats lost.
The EGV is a NGK racing plug.
VERY expensive, runs a wire instead of a full size electode.
Don't ask me why they are great, they just are.
Run them in high powered 2 strokes for years, resist fouling. As for the numbers 9/10 etc. this denotes how (hot) the plug runs with NGK the lower the number the hotter the plug.

Why can't i space the plugs back.
Is there no chance of collion with a tip if just 1 spacer is used??

Correct. Higher numbers are colder plugs. 9's are usually enough for mildly tuned motors. If you see heat burns on the threads, you need colder plugs.
I got this idea from Pineapple Racing . Talk to Rob (graduated from Hawaii hence the Pineapple name),
he insisted I try the EVG plugs. They're actually motorbike plugs. They last longer than the BUR plugs that's for sure and resists fouling . I used B9EGV plugs.
He never mentioned about using spacers.

what about using these in a stock NA? I am not a fan of the BR9EQs that are in there now....and what has to be changed to use them--different plug wires or anything?
