i did this cause i have a rsx-s and a 8th, i've bought this before when i was bolt-ons. i thought it would fit the rsx but gave up the idea when i cut it up to fit my n/a set up i have now on my civic. but, recently a friend sold me his for 22.00 used without filter. so i bought it and i went from the bottom. believe me its hard to take off the bumper and just to be trying stuff takes time, but the weird thing is you do not really have to remove the bumper you can install a cai by just removing the side water guard. so here i took the time to show you it works and my iat(*f) ranges from 58-65 degrees on k-pro.......
theres a intake that came out on ebay that looks like the rsx injen replica..
First you do not need to take off your bumper only if you want more room, but you need to remove driver side water splash guard, old intake system, and washer bottle...disconnecting battery would be good idea aswell, just incase you need to unplug any sensors....
i got mine used so this is the one i used
ofcourse i did have to mod the tube a little by wrapping it up with tape around the maf sensor hole and drill a hole and put a rubber adapter so the intake sensor will fit snug
i also plugged off my iacv sensor so its easier to install and take the heat off the coupler and tb...oh btw i have k-pro so dunno if it works with other aps.
now that you've done everthing its time to go in, you have to go from the bottom up and it should make it easy..i just bend the bracket to fit,etc,etc......heres how mine looked after i was done..it bolted up direct and fit just fine the only thing that bites is its a ebay cai:shady:
if you use a 3"k & n filter you might have to figure out a way to push it in more( i melted the inside so it could go in more cause k & n filters have a guard so you don't push them in too much) any other good filter will work (fujita,aem, or injen)
