Just looking for some engine dressup, and I know it won't benefit performance at all, but are aftermarket radiator caps (1.3k) ok w/ stock radiator?
The manufacturer (ARC) has 3 different pressure available for the type: 1.1, 1.3. 1.5--I assume, I should get the 1.3k? Any thoughts?

 

I got the nismo one... no problems...

I really don't think a little higher pressure will make the radiator explode.
