Which cai is better, the cobb or frpp?
That is two different parts. The FRPP part is a snorkel that is before the filter that pulls air from the grill. The Cobb or FSWerks one replaces the flatten out pipe. I like my Cobb because it keeps the stock box. There is also a Mountune one out there too. Some like that one and some don't. You can't go wrong with any of them.
