Great write up! Good pictures too...

I think I noticed you the pipe going down to the resonator box... did you just opt to leave it in? If you ever wanted to take it out, there are a few CAI write ups that could show you how to do it.

dowNNshift - I too installed the K&N SRI recently on my '07 Si Sedan - major difference! The only thing I would add is that you might want to add some rubber washers under the metal-to-metal connections on the 2 connector brackets. I noticed after the installation, and others have as well, an annoying vibration that is felt through the pedals and steering wheel. You'll notice on the stock air-box that there are isolation washers for all the connecting points - this is what I have tried to do with the neoprene washers.

This helps to quell about 90% of the vibration transfer. I've actually spoken with K&N about re-engineering the connection points to isolate the vibration - they can certainly do a better job than I.

Also, have you noticed any difference in mileage? I took my Si on a 300+ mile roadtrip with the stock air-box and got 33 MPG - the other day I went on a 300+ mile roadtrip with the K&N and got only around 28 MPG - I was driving conservatively as well. I live in the Northeast so this could be the reformulated winter gas (they add ethanol which kills mileage). Thoughts?

Awesome diy post downnshift, helped me a lot, just installed the k&n in my beaut'! sounds amazing when it engages vtec!! WWOOOWW!! i was not expecting that at all, i mean g'damn... all in all very satisfied with it, 'cept for a few things... all the vibrations throughout the controls are very noticeable so im gonna have to try that idea SiCop had... also, when you have the throttle open all the way, its sounds great and deep but i get this very strange raspy noise at half throttle, which is what i always use in everyday driving... now i'm new to this but is the intake supposed to sound like this? the strange, not-so-aggressive noise is completely eliminated when i just open the throttle more. and it does go away instead of being drowned by a louder noise. anyone else gettin this or am i being confusing? thanks!

ps. for those considering this mod, dont let this post cloud your decision, i love this thing!

well i think i noticed that i used a lot of gas, fast, since i've had it installed. of course i get crazy with vtec but i've always been vtec-happy and i know how quickly i use gas when i drive like that. definitely use more gas with k&n intake+vtec compared to stock intake+vtec. but hell, all the more reason to love it.

so IF i inderstand right the stock resonator stays in place to bring cooler outside air? if so im gettin one i dont wanna take the bumper off for a CAI but in az its worth it but a SRI would be more user install friendly.
plus rep on that write up
