I got my hands on some of these spark plugs and i was wondering if they are good to use on a rb25de neo , factory N/A . Also, how do i measure the gap? i just tighten spark plugs all the way .

thanks

Google what the spark plug gap is and that will tell you.

The plug is a cooler plug and might foul. Give it a go and see.

NGK recommend tighten to around 20 ft/lb - COLD.

I just read that gap 1.1mm is fine on rb25de neo and the bcpr7es plugs I bought had an abbreviation of -11 at the end, so I'm guessing they are already gapped to 1.1. I also read that the recommended plugs are PFR5G. It it worth just testing the ones I got or should I swap em for the recommended plugs?

For an na 7's are over the top but u can try them and let us know )

Correct that the -11 means a 1.1 gap.

Depends what you consider worth it.

They will more than likely be ok, but being colder and in an na the chances are they will foul easily .

I use them, but my car is running 20 psi .
