Um, there is no evidence to prove this.
Here are the following more popular options and my opinions on them
Conforti-Best IMO. Has very good heatshielding and uses foam(ITG) filter
Ecis-Comparable to the conforti but uses a K&N type filter
Gruppe M-Just a bad design imo, but people say it sounds the best
Dinan-aluminum, a true "CAI" but runs the risk of hydrolocking
Benfer-same an dinan but CF
AFE-very few comments on this so far
