Anyone got this yet?

I'm not sure what the MR means, but the Injen has always been able to convert to short ram, so can the K&N

Whats the difference from the regular Injen CAI? Looks like the same to me

I don't believe there's an MR for the TSX. That intake looks more restrictive than the RD anyway.

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

Hey guys, I just wrote Injen. It appears that part number SP1431 is this intake with the MR technology which is tuned for each vehicles fuel/air ratio. It is listed on a few of Injen approved on-line vendors. However, it is not even on Injen's website?????If it is for our car I requested the Dyno results so we can all compare the RD1430 and this "new" intake.

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 think it's just a gimmick.
Yes, there's such thing as a tuned inlet tract and I am sure it works but I guess this is what we call advertisement.

when will they release a cold air intake specificaly for the 06+

i went to Injen @ Pomona, CA few days ago to check out the R&D on my friend's IS350, and the designer of the intakes for TSX said they have a new product 1431 for the TSX now, its just not selling in the market right now.
so what indytsx1 said i can sure thats true =)

indytsx1

good point tsx536, I have a stock AT and want to do some mods, Hondata, Intake, etc. I will contact Hondata to see what they think. I hate to spend the extra if the RD1430 is the best.

indytsx1

This is what the rep from Injen wrote to me "SP1431 is the replacement for RD1430. Performance wise they are on par, however the Air/ Fuel ratio for the SP1431 has been fine tuned and is going to be closer to your factory setting".

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

According to the pic, it looks like the pipe dia is smaller.

Stokeless_TSX

so thats the intake the shop i go to was talkin about....hmmm im curious

indytsx1

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.

is the only advantage to running this in SRI mode for the easier installation, or are there other reasons too?

-vasu

Maxboost

There are couple more advantages such as
i) Easier to replace the filter when needed
ii) No need to worry about sucking in the water

Tsx536

You should also get a little more low end power, but less mid/high end power.

Ask if they have a true TSX dyno this time.

raheel616

again, lol, will they have intakes for 06+ models or will it all be integrated between all years

WlcTL

hey guys i found this surfing it seems to be the same a rd1430 but it calls it the sp1431 ??? misprint? http://www.cardomain.com/shoplist~t~...ke%2520Systems

indytsx1

LOL, didn't you read the above comments.....The SP1431 is the whole reason this thread was started......19 with a TSX?

JShamoon

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

Something's not right...

indytsx1

very confusing! I'm an engineer and this is not very easy to understand. Maybe I'm missing something. HMMMM....

It's probably just the smoothing configuration in the software.

Stokeless_TSX

or it could be Paint or Photoshop. =P

It appears that the MR intakes are to accomidate cars with MAF sensors.
The TSX uses a MAP sensor, is there any more info about this intake being available for the TSX?

loulinjai

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?

CKcentral

I heard not that much..maybe a few HP...but im not sure if it sounds different though.

TSX420J

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....

TSX420J

I take that back since I looked at the graph wrong. now cant really tell the difference.. except the torque curves are way higher with the mr version...

JohnnyMilano

im a bit confused....but i have ordered the sp1431 and it should be here within the week. Has anyone had experience with this CAI yet?

TSX420J

Can someone please elaborate on this subject since I posted the CAI dynos specifically for the 04-05 tsx??????


(Cough, cough) JTso

Reach

Truth is, they're all roughly the same. The big part is just getting one, that will provide you with the gains you're looking for.

raheel616

i think i might order the sp1431 next week

I will be doing $270 shipped on these if anyone wants one.

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
