Was searching the forum for a DIY and some more info on the topic but i didn't really see much or I didn't search long enough
So I'm Just wondering which provides more gains ? A single Cai or dual Cai?
Obviously dual would mean more air and more air better combustion
But is it really worth it to buy a a dual Cai over just a single, intake systems I know don't provide that big of a gain but would dual cold air intakes provide a significant difference?

Thanks

And if there is a DIY on the install could I get a link ?
