"The + to the Roar Intake is that it doesn't use oil to make filtration work, which is good for the whole intake system because that solves some of the oil buildup in the intake plenums"
Actually that prblem is caused primarily (probably entirely ) by the EGR.
Get it dynoed. We heard in a previous episode how the Monster flow was definately better, yet was inferior to KKM on the dyno. The KKM flows a hugh amount of air when analysed (see FAQ, intake comparison) about 40% that the stock SVT airbox (which is about 30% better than the SE airbox). Even if you get can more airflow, I think the KKM is able to provide all the air this car can use. I believe the key is to reduce the heat soak and air turbulence to the MAF (airbox with good cool air feed and MAF screen). I am currently evaluating just that (and 1 week preliminary opinon is very encouraging).
