I picked this up from somebody in the US, he got the manifolds and had them cut already, so basically it was just a matter of installing.
One thing I can say, WOW!!! The thing has much more response, I also have mated to it a Toda throttle body, with its taper design should in theory force the air in at a higher velocity (venturi effect).
Also had a friend fab up an aluminum pipe for the air intake pipe, the stock rubber piece just didn't fit quite right as it is too stiff to bend in shape. Plus it had a tear in it where it mated to the throttle body.
Here are some pics...
You can see the difference and quite a difference it is between the RBC and PRC manifolds. The air doesn't have to fight the IM to make its way into the engine. It is now a straight shot and it shows when driving. The runners are probably pretty close to being the same length, just straighter.
It does sit awfully close to the radiator support bar, but does not make contact. I would imagine if somebody has the shitty stock rubber mounts that there would be a very HIGH chance of it hitting. If anyone still has those stock mounts, CHANGE THEM NOW!!! Seriously, not sure why Honda went with the super soft luxury mounts. Other things that need to be done are the a/c line mount needs to be altered somewhat and the bonnet holder needs to be removed, mine already was when I installed the bonnet dampers.
I highly recommend this small upgrade. I would be loving it right now, but Saturday night somehow the daughterboard in my KPro fried, removed the daughterboard and waiting on Hondata's reply as to what I can do. Currently the car is 3900rpm rev-limited with a CEL on. Can't connect to check the code as it no longer communicates.
