Another issue with air intakes is if they do not retain the stock I.D. of the MAF housing the MAF will no longer be calibrated.What happens is usually some of the intakes have a slightly larger I.D. than the stock MAF housing allowing for a lean condition to happen because the MAF is no longer calibrated.Some of the ones that retain the stock MAF I.D.: Perrin,Cobb,TXS and APS(65MM). Some of the ones that don't:AEM,Greddy,GP moto and the worst of all -Injen.Also the stock air flows more than enough to handle up to 325hp.Intakes,once tuned,rarely shown any gain over the stock airbox under said hp.For people that just want the sound or alittle more performance from the stocker,use the "silencer delete" mod or the"velocity stack" mod.
