There's no way that thing fits on a TSX.

O sHit~ This is the 1431???? Someone on the "other forum" has sent an e-mail to Injen, their reply was another 8-10 wHP on dyno than the 1430 Injen CAI that we are using now. Hope it goes to production sooon.

Found some more info on the Injen website about the MR technology. Basically, they are saying that with most intakes, the Air/Fuel ratio will become very lean when running it with the standard ECU. There new MR intakes are suppose to be tuned for our specific cars so that the A/F ratio is more ideal.
This sounds like a good idea but I would think if you have Hondata then it would not give the same results since you're tuning would probably be different from the ECU that Injen used to tune their intake. I'm not 100% sure about this, so someone please correct me if I'm wrong.
Here are some comparision dynos. This is not a TSX, it's a Miata I think. They are just using this as an example.

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

Below is the response back from Injen
The HONDATA reflash actually remaps the ECU to get the most performance out of your engine. Because we tune the intake to more closely follow the factory A/F ratio it will help that even more.

i) Easier to replace the filter when needed
ii) No need to worry about sucking in the water

What's weird is if you look at their dyno graphs, the baseline on the chart with their "non mr technology intake" is jagged, but the baseline on the dyno graph with the "mr technology intake" is smooth? See for yourself: http://www.injen.com/MRtechnology/MRtechnology.html

what advantages/disadvantages (other than installination and maintaince) does SRI and CAI have, i know CAI may suck up water if you drive in the ocean and hydrolock the engine, but how much advantage does SRI have over stock and also with the CAI?

I am going to buy a CAI soon as i do the suspension this month and am still undecided so here is all the info Ive collected so far...
fujita cai
k&n cai
injen
injen with mr technology
injen without mr technology
Did anyone find out if using the mr version with reflash would have a negative affect as to using the regular injen cai with reflash????
looking at the dynos I see that the one with mr tech has a lot more gains in the 3200 and on and the regular one only has a lot of gains below 3200 but really doesnt have any good gains after that....

Does any one know if the injen HYDRO SHIELD (a pre filter for the filter) causes LOSS of HP? biggest reason why is probobly much less serface area. what would be more HP LOSS BYPASS VALVE or hydro shield? would u get more HP gains with SR and NO H. Shield or CA with H.SHIELD? and last of all for TOP END power wouldnt a SR jenerate MORE power than A LONGER RUNNING CA tube, ESPESSIALY with the new MR CA tube being a lot thinner atachment?
some things I read: for every 10 degrees of cooler denser air u gain average 1% HP so CA is approx 24 degrees cooler
