Last night, I got my paws on one of them shiny new Skunk2 K-series intake manifolds (well...borrowed). My ex-AEM cohort Robert Green ([email protected]) brought it by to document the install+ fitment.
I think it's safe to claim that this is the first commercial install (outside of Skunk's facility) on the net as Skunk just barely shipped these out this week to vendors.
Installing the manifold is pretty straight forward, but there may need to be small modifications depending on your fuel delivery setup and other things leading to the manifold (extension of hoses, etc).
The OEM waterneck (to the right of the intake manifold) is completely replaced with the Skunk manifold as it has an integrated water neck. Right off the bat I noticed how this manifold is compact in design, it doesn't arch up as high, and the throttlebody isn't angled as aggressively as the RBC is/does. Oh and it comes with a thermal gasket :up: and provisions & fittings for 06+ Si's.
I have a slight issue with my EG being that I'm running an OEM DC5/RSX radiator with my setup, and the DC5's upper water neck has always been a problem for me when trying to run a RBC manifold. The problem is the upper radiator hose makes real bad contact with the TPS sensor because of the offset of the DC5's water neck. One reason I haven't ran an RBC is because I've been lagging on getting a custom aluminum radiator made (kinda price, ya dig?). Anyways, with the Skunk2 manifold, it actually just barely alleviates this clearance issue I have :dance: thanks to the compact design and no need for a throttlebody adapter plate!
I didn't see any downsides to this manifold, well maybe just a tiny one for the ones who just want a direct stock intake manifold replacement. The oil crank breather line or PVC line (right above alternator) doesn't have its own vacuum port for recirculation. You need to run a breather filter or tap in your own vaccum port. Oh I almost forgot, you'll need one of these fittings for the coolant temp sensor which this manifold has provisions for (see photos beloooow):
Can't wait to get my own S2 manifold for testing =D
am i the only one to notice the guy with the black and white mask?
Yea that bugged me out when i first seen it :wow:LOLL
but the manifold looks good i like the extra clearance it gives ya compared to the RBC. nice mani :up:
at one point I test fitted the sr20det visteon in my EG - using K-Tuned lower mount brackets for a traction bar and I had to angle the top of the rad slightly back for the cap to clear the hood. I am not sure about the mishimoto in an eg - but know it worked fine on ek & dc
I will try to get around to mounting mine sometime in the next week
edit - I think mishimotos "Overall Size" accounts from the top of the cap to the bottom of the mount pin
I've been rolling on my backup motor for over a year now, but the final gems for my next build are all in my possession.

This will be added on to the IPS K2 Mark III cams I already...
Hey guys, I’ve had my 06 Type S for about 3 years and its finally time for me to do my frank build. =D
I’ve gotten most of my stuff, just waiting on a couple things here and there. Here’s my parts list
K20Z1 OEM Overhauled valvetrain
07 K24A2 bottom end
O9 TSX Pistons
Manley H Beam Rods(Pending...
Hello all,
From my research online, I’ve found that the FN2 CTR and FD2 CTR are quite similar. Since most Japanese tuning parts are made for the FD2 CTR, will these parts made for the FD2 CTR fit on the FN2 CTR ? For ex. Toda ITB kit and cable throttle.
Thank you !
