Mr5 intake

Has anyone done this to their 1'er? The only one's I've seen them done are on the E9x and it seems they have more space to mount a filter. I guess what I'm getting at is it seems there's very little space to mount a good size filter down there? If you have it done please post pics.

The Dinan intake fits, more or less the same thing.

What kind of idiot would spend a grand on a Dinan intake though?

from mr5 tests I don't really see a point, the difference between the results seems close enough to me that just a couple degress or a change in humidity between runs would make a bigger difference. Just my .02

Well from the logs I've seen his style intake performs justs as well the DCI's and better than the stock intake as far as Waste gate duration, which means I will gain the benefit of less work on the turbo's. IMHO if I can help the turbo's in anyway i think it's worth doing.

The main reason I'm doing this is to cleanup the look in the engine bay. I'm not a fan of how any of the DCI's look Injen or AFE, but I want the benefit of the free'er flowing intake. I'm also not gonna spend a grand on the dinan intake.

I should have this on this weekend. I'm already finished with the box I just have to find the time to mount it.

Erv, when you mount it up, could you take some pics. I am on the fence right now debating if I want to go this route.

Its funny I came across this thread tonight. I was just gonna post these photos in a new thread. When we had our 1er forum and 1addicts meeting at the Ring two weeks ago... one of the 1er forum guys there with a 135i - had made his own Mr. 5 intake. He used common plumbing pipes from his local German hardware store. He painted the pipes in stealth flat back. He said it really did make more power. How much is anyones guess. He also said he had a flash tune and I think a bigger intercooler(?) pushing close to 400 PS.

Here are some pics of his car...













Also on an side note... My tuner (MS Tuning, ie Marcel) told me that the bext CAI is the one from Alpina. But they won't sell you one. The only way they will sell you one for a B3 (?) is IF you provide them with the car's German registration papers, plus a photo of the damage broken part. THEN they will let you order a new CAI box. lol

PS: I found this link with photos on the copy-cat Mr.5 intake on an e90 335i.

I have driven plenty of cars with dci intakes, aka throw a couple hot air filters on top of the block. All I can say is power loss... Also had an AFE intake on my car for a couple weeks, lost bottom end and gained no top end. Pretty much a loose loose situation. I didn't realize how much I lost until I reinstalled my stock air box. Although I didn't like the price of the Dinan intake, I liked the function and appearance. I bought it and i must say the car is much more responsive throughout the power band. Besides having a second filter, they also have a heat shield to block radiator heat and promote cold air flow to the second filter, as well as a water shield for the secondary air filter. The intake shown above looks really cheesy. Who buys a 40-50k car and wants to install some half assed hot air intake like that? Better off with stock airbox and a drop in filter IMO. Either do it right guys, or don't do it at all...just my .02

I get what your saying, but not everyone has a grand to throw to an air box. As much as I love my car I cant justify the 1k price tag for the dinan intake as nice as it is. I usually dont open my hood and show off my engine anyway, so the Mr.5 intake fit's my bill.

Just serch E90 post and look for the log's and testing that Mr 5 did on his intake vs stock vs DCI's. His intake has shown to lower WG duration which is the benefit of the DCI's while having IAT's as low as the stock intake.

DCI's IMHO are for people that are fully modded pushing 18-20 PSI where they need more air flow than cold air.

What good is more air flow if it's less dense? You're after oxygen contact not nitrogen content, since air is about 80% nitrogen. Cooler the better, I'd take half the air volume if I could get it from an oxygen tank ;-) my car does see 18 psi and the AFE intake still lost power, even through 4th and 5th gears. So there is no gains to be had from it. How ever, with my Dinan intake, the car is stronger in 4th and 5th than it is in 3rd. Nice ram air effects at higher speeds, of direct cold air.

As high as under hood temps get, dcis will never make more power. There's no direct airflow to them, even at road speed. With engine temps pushing 240-250 on these cars, how much better can that be over hear shielded cooler air from a stock box or nice aftermarket intake? My answer is simple, it's not better in any way. Thus my hatred for dcis, AFE open intakes, Riss, and any other half assed intake. Not to mention should some one want to see under the hood, a stock box looks clean and factory, along with some other intakes. Where open filters look like you bought them at Pep boys and used some PVC to make them fit.

Not trying to start any pissing contests, just stating my opinion. ;-)

The Mr.5 intake is basically a DIY version of the Dinan intake. If you seach E90 post and look at all of the members that have done it you'll see that it functions just the same with the secondary filter routed to the same area as the dinan intake. It is in no way shape or form a DCI. With logs by Mr.5 that shows that it works.

Some of the examples there look very clean and most people wouldn't know the difference when looking at it. Some members fabricate brackets and include prefilter's. If done right you can keep it looking clean.

When I say that those that are fully modded I also meant meth. Those that are sustaining not peaking the 18-20 psi range and trapping 120+ MPH need the flow of DCI's, but off set the extra heat with and upgraded intercooler and meth which keep IAT's in check.

I believe Mr.5 has a dyno attached to his DIY. It's was proven that its better than the DCI from BMS.

Update... Things didn't go as planned. They're is just not enough space to route a 3 in duct down to the bottom, one of the biggest problem I ran into was the damn brake fluid resevoir. I think a bracket relocation would help, but I didn't have one on hand.

I might try a 2.5 in duct on my next attempt. Also Filter size down below is also limited with an upgraded FMIC. I suggest no bigger than the Burger DCI sized filter if you have a bigger FMIC. Also if your running a BOV that's right next to the box you might not be able to do this.

As of now this is how I have it routed, I will try again and plan this alot better now that I know what dimensions I'm dealing with, and get this danm Mr.5 intake installed. Our cars are so limited in space compared to the 335i.

That dam thing (with the green circle in your photo) isn't the brake fluid resevoir - but it is the power steering resevoir.

On the gold 135i car I saw at the Ring... he routed the pipe to the left of that PS res, then straight down to the front spoiler opening. Maybe try something like that. ?

Do you notice any better breather now the way your setup is?

I tried routing it that way and maybe I need a more flexible hose. The hose I was using is tough. It would not bend or compress so I just couldn't get it down there. I'll probably need a 90 degree elbow like he had.

I'm gonna re attempt it here within the month. On a side note although not quite a Mr.5 intake, my butt dyno feels like I've gained the low end tourque that I lost with the DCI's when the weather warmed up without losing any top end power. I'm gonna reset my adaptations and go for a spirited drive

You need to use a 90 degree fitting right out of the box, like the German car shown above, in order to clear that PS reservoir.

Will the filter shown above even fit down into the front spoiler area with pulling the front bumper off to get it there? I was looking at how much room there is to drop one in from the engine bay next to the PS res and even the piping looks like it will be a tight sqeeze, let alone dropping the filter in this way.

I don't know the answer to that one. Only one way to find out! I think I would first just run teh hose down there... then attach the air filter from bellow with a socket and ratchet.

I remember at the Ring - some of the 1er guys were wondering how this guy with the gold 135i also installed his filter down there! I think it is a tight fit! I did not feel like getting on my hands and knees - in the gravel parking lot of Bruenchen - so I don't have a photo to show you.

Yeah you would have to install the filter from down below, also at this point that 90 degree piping right out of the box is a must to avoid the ps resevoir unless you mount a different bracket. The thing that I'm running into with the 90 degree fitting is trying to find one thats not huge. My forge DV's are getting in the way.
