Yesterday during work when I have 1.5 hr of spare time to burn I did a little testing of the stock intake. I tried removing all parts of the stock air intake except for the huge blue cover box cause it needed to hold the filter down. By doing this I was hoping to free up air flow and MAY gain some HP/TQ enough that I could feel it. I removed the 2 piece tube that goes to the left side of the battery and the piece that's attach to the blue box with 2 screw. The result was 100% disappointment. I feel there were no HP gain at all. BUT instead I could feel that Torque is for sure LOWER than with the complete intake in the lower and mid rpm range. NOT GOOD. NOISE level went up like you have a tiny N1 muffler in front with a silencer. If ur into the HondaZz stuff you may like it however the sound is not (as bad as) the Hondaeeeeee...e...e.e..EEEEE. In high rpm and on highway speed above 75mph the car seems(not official) to pull a little harder and runs smoother like you have an entra gear......BUT you can hardly feel it and the result might due to the fact I was flooring the gas more often and harder cause of the lost of lower and mid end power. I think there's a reason for the tube and it's location. reduce noise and get air from the coolest spot in the compartment. I'll install a real intake soon just to test it but not going to expect much cause the location that is free for the mushroomhead filter is the hottest spot in the car where the radiator fan BLOW ALL THE HOT air to................I just wanna say in short/long DO NOT MESS WITH THE stock INTAKE.......I wouldn't. 1% gain and 99% loss AIN'T worth it................BTW is "ain't" a word?
