I'm going to skip over the perfomance vs sound part for now.


Pros is throttle response compared to not doing the resonator bypass mod & K&N drop in and you get to hear the turbo & BPV in action.

Con is if you go full CAI you gotta take the front facia off to instal it.

Your statement leads me to think the Injen in CAI would be best...lowest temps coming in. and since it is a full CAI it cant possibly pull under hood air correct?

The videos of the K&N do sound great though..think there is any perceivable difference in noise between SRI and CAI?

Haven't taken the car apart yet so I don't know if the fender where the filter sits is is truly sealed off from the engine and radiator. A few of my cars the fender had small gaps where sitting at idle the engine air bless into the fender. My Legacy is airbox mod because CAI kept getting wet when the rain wend down the hood scoop and soaked the filter.

As for sound, most cars it changes the tone because the length of the piping and where the sound echos. Sri going to be louder.

Lol reason I got manual, finding a woman that drives stick is a challenge on top of other things I'll leave out this thread. My issues weren't fording the rivers and streams, It was extreme rain and car washes that would set off the MAF volt spikes. I could have closed off the diamond pattern on the hood scoop for the turbo(where it trickled down the intake and to the fender) but decided not to. In other cars the CAI was louder and sportier the way it echoed around the engine bay. CAI to me sounded better because it was just loud enough and magnified the turbo howl. I say find someone with both setups and ride along. Youtube can't really give you accurate sound even tho the quality of videos is getting better over time.

That was suppose to say Sri louder/sportier. Phone changed it to CAI.
