i just installed mine about an hour ago. performance wise i have no idea, but it certaintly looks better than stock. the afe is more than double the money. i just got mine for $180 shipping included. im sure it might flow more air, but even if i wanted to buy different filter for my S&B its still way cheaper than the afe. its up to you, but unless your doing alot of mods its not gonna make a difference except for in your wallet. just my opinion
