hi, i just bought ngk br8eix plugs for my evo 8, they are pre gapped at .28,
what gap should i change them too...?

my mods

stock ignition
gt35r at 1.8 bar
93 octane

is a smaller gap better for a turbo like gt35r and again what gap should i re gap my plugs at?

 

35psi for me with a 35r I had to run .018, anything wider would blow out! every car is different I would start at .024 see if it breaks up if it does go down to .022

 

35r here 26psi pump BR8ES at .026. 140k mile stock coils and never had a spark related issue

 

1.8 bar should be fine with .025"

 

it will depend on what the car likes. im running br8es gapped to .021
