I honestly don't see any differences with the RD version. They dyno graph is also far less convincing than the one they tout for the RD.

Hopefully they updated their design where the IAT sensor hole is in a better location. In the Injen version I have, the wires are almost being detached from the harness! 
Additionally, the position places the IAT plug right next to a radiator hose.

Both this intake (Injen MR) and the existing one (Injen RD) will fit on an 06+ TSX. I've had the RD on my 06 TSX myself.

I wrote him back with a question in regards to having the HONDATA reflash and if it messed with the performance since the MR Injen was designed for the factory air/fuel ratio. I'm a newbie but don't think the HONDATA reflash messes with the air/fuel ratio. I thought it only changes the VTEC "kick in" point. Well, if this MR Injen is the replacement for our TSX then I'm hoping that means the RD1430 will be on SALE soon

Looks like the lower intake tube has a smaller OD than the MR version. People have reported (and proven with dynos) a torque loss in the low end after installing a MR CAI, which is likely due to the larger ID intake reducing the charge velocity. Same reason why bolting on a 3" exhaust or poorly-matched cat on a small 4-cylinder engine will rob power in the low end - not until the upper rev range is the engine pumping enough gases to fill the larger diameter tube, so the gases move slower and the scavenging benefit is lost. But when you add a supercharger, gas volume increases at a given RPM based on boost levels, so that 3" exhaust all of a sudden becomes necessary to not lose power. Check out the 4" intakes and full exhausts some Supras use with their big honkin' turbos.
I can't figure out which of the above dynos is the MR and which is the RD though.
Porting the IM is very easy; it can be done with a Dremel and the right bit. I did it without removing it from the engine (which is saying a lot for me!)

You will hear a note cause by the vibration of a column of air inside the bottle. An intake is the same. For a given diameter and length of tube, there is a resonance frequency. Where this matches the RPM of the engine, you will find a torque hump and lean spot. When we switched to an Injen cold air intake we found the resonance point to be around 4500-4700 rpm.

To clarify rmpage's post, the MR is the new version, the RD is the 'old' version. Where he refers to the MR I believe he means the RD, as it is the older existing model.

hey rmpage~
How can you port & polish the IM without taking it out???? Did you see any gains after port & polish???
I've installed Injen RD CAI, DC Sport Header and your High-Flow Cat, the result is impressive. No CEL after install~!

I didn't polish it. That would require removal.
When I installed my bored TB I needed to enlarge the IM port to match the new ID of the TB. I stuffed a bunch of rags into the manifold, sealed the outside with tape, and ground away the excess metal. The angle was such that the rags caught the shavings without allowing any to fall down into the manifold plenum.
As for gains, the dyno registered about 1hp more after boring the TB, which is within its own resolution. So for NA applications it is sufficient to say that a bored TB on its own is relatively useless.

Hondata didn't see a gain with the TL TB test either though so it doesn't really surprise me; I got it done in the hopes that we'd be able to drop in larger cams by now.
