sound wise, the 5spd will deffinately notice it more as it'll chirp every gear change....whereas in us automatic owner's cars you barely notice the thing...especially if you had an exhaust before hand. It deepens up the engine note, but the best thing is it removes that annoying stock "rattle" that I used to get when I had the stock intake box. I dunno if anyone else knows what I'm talking about...but anyhow, I've been through about 5 different intake setups.....the CAI is deffinately deeper, and deffinately makes for a quicker Accord since the power band is so low in the range......where we actually are making a little power ;o).
