That black brace in on e92s only. The e90 does not have the brace. I don't know how much structural integrity it adds, but I too would not like to remove it and that's why I haven't ordered a cold air intake myself. There doesn't see to be a way to work around it either....

Does anyone know if this will fit with the Stett charge pipe?

This is now on my wish list. I am currently running the BMS Twin intake.

I do like the BMS.

Funny thing is I took my car to my tuner (he tunes mostly domestics). He used to tune all of my cars in the past (including a 04 Cobra with 91 MM turbo kit) 1000 rwhp capable.

Reason I tell you that is ...he had a fresh perspective when looking at my
335i. I was having him look at the AR Downpipes I bought to see if they could handle it install and get a estimate.

His first question when looking under the hood. "Has anybody created any kind of Cold Air Intake that gets all the heat out of the hood?" He didn't see anyway for the heat to effectively escape or possible feed back in to cool the motor down. He said the more you mod the more heat. The more heat...the more you slow down.

It looks like that is one of the things this does accomplish. Would be interesting to chart rwhp gains with JB3...Vishnu tunes? Also, if this did drop temp by as much as 40 degress Fahrenheit ...makes you wonder how good this would work with meth?

I am going to add this sometime in the near future and see what happens.

So I can't wait to actually add race gas, for the temperatures to rise so boost peaks, and then see what this cold air sucker can do.

I'm disappointed about the inability to use an M-aero bumper though. I think this is a problem for the Dinan OC too. Is there a work-around? Something a body shop can fix?

I've been contemplating body kits as my next mod because thus far my sleeper car is putting everyone to sleep.

The Dinan OC is somewhat of an issue with the M-Tech kit. At least that is what I've experienced on my E90. As you may know, when getting the Dinan OC, there is a new passenger foglight available that gives more clearance for the OC. The M-Tech kit does not have this passenger foglight.

What the M-Tech passenger foglight does is push the OC back into the wheel well. So much in fact on my car that I had to bend some of the fins of the OC for clearance.

I called Dinan about my displeasure with this and all they said was that they don't support the M-Tech kit. WTF. Whatever, it works now. No real issues, other than having to force the passenger foglight to align properly, while pushing the OC as far forward as possible to allow for tire clearance in the wheel well. The back of the foglight and OC are touching. Absolutely no clearance.

It does with the E90

I highly doubt that you would see a 30whp gain with any other tune. The dinan tune tappers off much more aggressively than other tunes and probably does so even more aggressively with hot intake temps. The large gain is most likely due to the tune not retarding boost nearly as much because it's actually getting cool air.

So the intake is doing is job and seems to be doing it well, but I wouldn't expect to see this kind of gain with any other tune.

I am wondering how much gain compared to other intakes.

They are offering 20% discount on it now!!! that's about as much of a discount as you will see.
I'm getting ready to pull the trigger...

[bboy8282]

So does Dinan still honor their warranty if the engine gets hydrolocked...lol...?

The 20% off does not apply to the CAI. Perhaps you were referring to the OC though, to which the discount does apply.

I was quoted 20% off the CAI... the dealer just said it could take a few weeks to get in though

[ducati955]

whats the deal w the brace? all e92's have to have it removed?

[ybbiz34]

Hmmm...were you quoted this by your dealer or Dinan?

I was considering pulling the trigger before this discount but this could seal the deal.

I am first time poster here. I have been reading about CAI for a long time and there seem to be claims for rather huge horsepower gains. BMW makes an OK car. I would like to think their engineering department knows what to do and how to do it. I would bet that any car company that could get an additional 30 HP from a few bucks of plastic tubing would instantly add it to the stock car. Bragging rights! My Z4 would have 245 HP instead of 215?

I believe so. Mine had to come off and that caused the greatest delay in my installation as the tech doing the work stopped to call Dinan just to double-check it was okay to remove.

Dinan said it was cool to remove, but still, removing such a beefy looking brace seemed a bit odd.

BMW claims 320hp for 335is, but 335hp for the same engine in Z4 sDrive35is due to a less restricted intake.

One of the reasons they Don't do simple hp increases are for insurance purposes. Once you break a certain amount of hp/tq, rates increase and can push buyers away. Also, that extra "plastic tubing" does, as suggested, cost money. Manufacturers cut costs anywhere they can and by penny's on the dollar. No idea what the extra cost would be to BMW, but would most likely have cost them big $$$. Also, if they did this, there would be no reason to modify!!!!! That's part of the reason I bought a 335i

[vegasspeed]

BMW wouldn't just throw this on the car for an extra 12 hp. That isn't there goal in mind. They need to make money and this is not something all buyers will want or need. I really doubt it feels that much better honestly. I have driven cars with 30 extra hp and it still won't jump out at you. Just my two cents.

[vase330]

You are right, but its the little additions that add up to a big number you will absolutely feel in the seat of the pants. DP, tune intake etc all add up to a huge difference. I bought this and got in installed back in the August. Awesome! I still love it and not looking back.
