I am really new to car modding and are just trying to get my head around the basics.
I am currently on my Red P's, which is an absolute bitch cos of the specific laws.
Anyway i am considering getting a cold air intake manifold insulator for my r31 skyline.
So my questions are:
Are they actually any good?
Is it as simple as removing the upper manifold to install? or do i need other parts?
Are they legal for me on Red p's and what about green?
And are they safe? is there the potential to cause damage to the car/engine?
Cheers
