P2R does not typically produce ported intake runners for the CL-S, but we can have them done. With the platform being a bit older Acura has increased the cost of the runners to be bought new, so it would probably be less to have your OEM runners sent in and ported if you could do without them for a little bit. Again, something we can definitely get done, just has a bit more cost for the new ones now that they are not in production.

Chris please send me an email to sales@excelerateperformance.com with your information so I can check it.

Ok. Got it.

Hey kdawg, thanks for getting back to me. I didn't do anything to keep the butterfly valve (TB) open, I just bolted the TB back and hooked up the TB cables. Was I supposed to do something different? And yes, in terms of how I hooked up the piping:
So if you're looking from above with the "A" emblem orientated as such, I plugged up the port near the IMRC motor on the left and hooked up the return hose from my catch can to the "L" port (my can is on the drivers side: so PVC to catch can to L port). BTW, could it be the PVC seal? the carb spray didn't say otherwise. The brake booster and vac lines were hooked up as well. I didn't leave anything unhooked it appears.

I used the P2R manifold gasket, TL (to spacer) gasket, and CLS TB gaskets and torque all to spec (per the service manual). Still boggled, but with such a big swing in RPM at idle (1000-3000) I must have some leak somewhere!

Thanks for the help

hey i didnt have any problems with idling at all i left iat hanging somewhere because i didnt want to make a hole to fit it into the intake and i dont think your idling issue would be because of that. did you check my thread with the pics? there a few openings that need to be plugged. i used the p2r gasket for the manifold and the throttle body.
did you leave the butterfly valves open?
pm me back.
