When I was looking, I found a BMW dealer in SoCal selling a new Dinan CAI for $550 on ebay. Full warranty, numbers, etc.
I think the AFE or Injen are half of that price with the same features. |

Correct, throttle response is controlled by DBW and ECU. I ran stock originally and was keen to fettle intake to improve throttle response, help keep iats in check, any bump in oomph would be welcome and add some sound/character. Stock intake, stock airbox with drop-in, mppk intake with drop in then lastly oem airbox, drop-in and air scoop. Have seen small incremental improvements and ram air effect of scoop was a worthwhile add-on to oem airbox and a drop-in filter. Comparing oem airbox, afe dry drop-in air filter and AFE DAS air scoop to Dinan CAI with AFE DAS, my cars DBW seems to have adapted to Dinan CAI favourably, by this i mean any 'lag' is lesser whether on partial or WOT. Car feels more responsive / urgent, especially with jb4 in maps 5 and 6. The above may also be true of other CAIs but I can only comment based on my experience. BP

I've seen no evidence that an intake is required when tuning (why would you need it for Stage 2 map of Dinan) or even beneficial on the N55 platform with or without tune. It's such a quick instal; easy test would be go to the track make 2 passes on stock intake, let car cool down and do another couple passes with the Dinan. If the claims are true then 15 ft-lbs should get you an extra 1-1.5 mph at the end of the 1/4. If you want sound and actual power improvement get a hi-flow catted downpipe or catless if you are so inclined. I've had aftermarket panel filters, open intakes, closed intakes and none of them produced any results at a track. I get sucked in like most on wanting more power, this car I'm taking a pass on what I've personally felt have been $ for nothing. Tune, downpipe and mix of E85 or race fuel are only cheap mods for this platform. After that you need to upgrade the turbo. Intake and non-downpipe exhaust mods are for sound and they are expensive. But, if you've got $ to burn and like whooshing noises then who am I to say what you should value with your own $, enjoy.

Bottom line from all this, gentlemen, is that on pretty much any modern ECU-controlled car, intake modifications really don't do anything right off the bat unless the ECU itself is modified, i.e. a tune. (This is why most performance cars don't have a dedicated air intake, i.e. 'ram air', these days. You're not forcing air into a Venturi plenum on top of a carb, ya know) Also, just to make another point: The reason the OEM intake can't be improved upon much isn't just ECU control and drive-by-wire; it's the path that fresh air needs to travel in the sealed intake system in our cars. Engineering-wise it's not very efficient at all: the ambient air is taken from a small hole on the passenger side just in front of the radiator, which is turbulent by nature because of aerodynamics and heat dissipation. Then, it has to do a 180 -- literally! -- to travel to the driver's side of the engine where the filter box is. Air being forced to turn in the opposite direction on a dime is never good for flow. So then that begs the question: "So why not use an open-box system?" And get the air from where, exactly? Besides, there's way too much hot componentry -- including not one, but two oil coolers, on either side of the OEM airbox -- for an open cone to work well. Heat soak city.

Yep, tending to agree with you m235iGuy, it reads like Vmike is on a crusade.

I'm not saying that Dinan is lying. I'm saying that Dinan isn't being clear. Big difference. And you can go on believing that my scope of reference is just forum posts; that's fine. You're wrong, as stated earlier. But that's fine. That's your opinion.

Or any other CAI vendor. I've seen similar claims of HP/TQ #'s. So presumably there all being unclear not just Dinan.
EDIT: by the way, check out afe - claims of 25hp/35tq and I don't see any docs supporting their claim

After installing my dinan CAI today on my tuned stage 2 dinan.
I can state that its noticeable. the response, the power is not like a tune, but its slight and its a little more sound, a decent increase in throttle response, and power. i cant speak for an increase on a stock car, but with the stage 2 tune. its def worth it imo. especially if u go with getbmwparts.com, the price is right
