hey what colder plugs are u runing IonFeright?? how much are they? are they 2 step or 1 step colder plugs?? what do u recomend?? and if i dont have nitrous yet will it decrease my performance at all??

i have a injen intake, gmpp performance catback exhaust, lsj manifold and am seeking nitrous later on in the spring.

 

1 step should be fine and I don't see why you would notice a decrease in performance.

 

ya beats me

whats the difference of 1 step or 2 step colder plugs?

 

The colder the plug, the less likely it is to cause pre-ignition (detonation). Too cold could cause a loss of spark energy though.

 

I run NGK BRK7E-11 2 steps colder gapped at .035

The 2 steps colder plugs make the car feels pretty sluggish without the n2o.
