The cold air feed was directly connected to the intake box so it left with it

that diy airbox served me well, I salute it
Thank you! Your car is so quick!
The P2R gasket for the 06+ Civic Si only fits Euro with RBC. You'd just buy one for a Euro otherwise.
I've got the P2R intake manifold gasket but not the throttle body one or spacer yet. I might buy Justin's P2R TB thermal gasket and bore it out to 64mm
I totally understand, lol. First post was only meant to be 500 words or so, but I started typing and didn't stop for 45 minutes, 6500 words later it was done
