Lots of the responses to this post are from people with pre-2010's. I wouldnt waste my money on a CAI, just buy the exhaust you want, a $50 K&N drop in and an SCT tuner. I am no expert, but on a N/A 4.6 the stock CAI must be sucking plenty of cold air.

 

well for starters, the engine is 2010 is pretty much the exact same as the 05-09's...for 1300 thats a major rip off for a cai and tune..i got mine for $600 with udp's included. NO WAY would i buy corsa exhuast...i've heard too many ppl around here where i live that don't like them....plus corsa is overpirced too. if you want that rumble and practically no drone...bassani's is the way to go...i agree the frpp is a joke...me personally the stingers they have is really great and thats because borla makes them so u know you're getting a quality product...the reason you want a cai is because when the engine is running at a higher rpm's the rubber inlet thats stock tends to stop flowing so well and starts closing itself off due to vacuum effect. heck, ford claims big hp from shorties and in reality you get practically 3 to 5hp from them.
