The way I see it, post maf tubes and K&N's are an easy sell if you are chasing for more power. It's cheap, effective and an easy 8-10whp. CAI gains over this setup are at the top of the rev range. Though I have noticed that AEM's give a bit more than others under 6500rpm too. Most likely from their ETI technology
