Sup Everyone, i am trying to find out what to gap my spark plugs to.

the spark plugs i am using are NGK BKR6E-11. i have a poor man's type r swap (B18c1 gsr block with a b16 SI head). i have searched and found some stating .044 to .051 gap.

thanks in adance!

 

Just go out and get plugs for an ITR.

 

i already have the plugs that i am going to use! i am asking what i should set the gap to with the BKR6E-11

 

Just leave them at 44thou.

 

i thought with the new bosch 4 prong gapless plugs, we didnt have to worry about this stuff anymore...

 

thanks Kataku2k3.

and gatesrex91, i only use NGK plugs

You don't really use those, do you?

 

Yeah.. for anyone that cant take the hint.. Go NGK.. or whatever came stock in the car. Yeah Yeah I have heard all the arguments on this subject. Just think, your messing with the combustion chamber when you mess with plugs.. Don't ya think its better to use what the engine was designed and tested with?

As for the gap question.. Run the gap as wide as you can for your setup.. But NOT wider then recommended by the car manufacturer. If your running higher compression, whether its by engine mechanics, Turbo, Supercharger or you have a NOS setup you may need to close the gap a bit. Start with a little below stock and see how it runs at high RPM.. if there is no miss leave it. Your not going to gain performance by adjusting the gap if the engine is running fine. If it runs good leave it.

Also think about the heat range of the plug your using. A common misconception about gap is that it will change the heat of the plug. This is not the case. If your pinging, use a lower heat range plug... don't close the gap.

 

I like .039 on an all motor car. If you are using a hot ignition like MSD you could open it back up to .045 or more if you choose.
