Subaru FB20B and FB25B - OEM vs aftermarket CAI (Cold Air Intakes)
There are some things to consider before installing a CAI. How is it designed? Will it produce more power? What are the downsides? I run through some notes on the subject.
While this video talks specifically about the Subaru FB port injection engines, the ideas can be applied to most modern internal combustion engines.
Subaru Impreza, Crosstrek, Forester, Legacy and Outback share the FB20/25 engines.
