Confused need help about spark plug

[cano86]

I checked the spark plugs in my car and they are NGK but instead of saying BPR6ES they say BCPR6ES does this matters or are they the same thing.Some help will be appreciated

I know that 3000GTs take those, but I don't think they are the good in the 4G63... I would scrap them and put in BPR6ES plugs right away. They might be the same heat range, but I wonder if the reach is the same.

bet the electrode is "v" grooved which in a way, is better since this forces the flame to be directed to the outside of the electrode and has less chance of 'blowout' due to high compression.

Oh, gotcha ..."GM" style plugs that uses the 5/8" socket instead of the common 13/16" socket.

Exactly they are 5/8 socket
