My 2011 wrx stage 2 have the aem cold air intake with protuned! The car runs much better that the oem intake. My afr at wot is 10.3 10.4 ( safe ) 0 knocks and everything perfect.

Process west tmic
Synapse diverter valve
Aem cai
Tsudo bellmouth downpipe
Invidia n1 dual
Protuned 19 - 20 psi.

The difference with oem stock air vs aem cai with protuned is huge.
