The Injen CAI necks down at the MAF to the stock diameter. AEM's don't neck down and use their ETI technology to try and correct the MAF voltages. Works fairly well and you don't need to tune it to make intakes work.It also helps preserve older tunes as we know ECU's like to have a mind of their own.
I also see your Tanabe Y pipe is for sale haha. Is there going to be a Motordyne and Top Speed sale also?
