There are a couple different radiator caps around...1.1 kg, 1.3 kg, and 1.5 kg I think. Anyone know which is best for a tC?

 

the higher the kg, the more pressure it can withstand and the longer it keeps the radiator from boiling over. something like that.

doesn't really matter unless you plan to put your tc through some really hard runs and it won't have time to cool off.

 

u have to becareful what type it is, even if its TRD. I think the tC is type N but im not sure, either N or S.

 

its type N

And what does the N or S designate?

 

its just the fitment

 

I just got my 1.1 today Little more bling, supposed better cooling, even though I think us SC tc's have a lower thermostat, it couldnt hurt!

 

does the trd radiator cap actually make a difference?

 

how much gain do you get from it?

 

none that ull notice
