You're right. The M235 has a secondary Oil heat exchanger with coolant flowing through it. The 3 series doesn't have that, its purely air to oil.

There's an extra oil-water heat exchanger (number 26 in first pic) that blocks access to the inlet, so you can only see the retaining nut from below. This is the same bugger that makes installation of the EWG wires a bloody knuckles affair.

The 335iGT looks like it has the same setup as the M135i...
Ah indeed. Didnt know about that difference. Tnx for explaining.

I see the bolt that holds the pipe, but theres a hose and sensor going to it also that isn't shown in the ETK. Looks to go to the top of the motor someplace?

Any reason the E-series N55 gets a full replacement inlet pipe, but the F-series is the cut and join type?

Default Logs with inlet - 09-30-2016, 09:14 PM

I have install the inlet now on a stock n55 EWG turbo. I have here two logs. The first at 23.01 is with stock inlet and the second 5.40 is with pure inlet. For me looks same, but the car feels better when i accelerate.

Possibly because the E's OEM pipe is quite restrictive for most of it's length. Only seen photos of the F but it looks like the restriction is at the end only.

We really need MAF delete option for E series so we can just slap a cone on the Pure inlet. Can't get better than that.

Or at least route it with better piping.

I think that if you request a new board chip from Terry / Steve (the one needed for the BMS PI controllers) and load the latest FW you'll find it's MAF delete

would we need to buy a new jb4 for a MAF delete?

My understanding is it's a straight swop of 1 chip. I've got probably one of the first N55 boards from 2011 and, from what I understand, I could just swop a chip - no need for a new board.

Not sure of cost etc though

I think all new boards come with the new chip - if you have a look at the N55 install guide on the BMS site it now has a big red cross on the MAF page

Easy install? I'm deciding if I want to just throw it on or if I want to hold it until I upgrade the turbo (probably to a Stage 1, because a Stage 2 in NYC traffic is a waste).

If you were to throw a filter right on the inlet would this need to be blocked off? I don't even know what it is.

Has anyone tested these on a FBO STOCK turbo? wondering if similar power gains are possible on the smaller stock turbo.

Ths install guide is for the jb4 stage1 for thd n55
It doesnt say unplug the maf, it just says leave the maf as-is, meaning the dme still uses it

Looks like you're circling the hose for the pcv?

Good point - wonder what the new top mount guys are doing? I'd assumed from a few comments I'd seen that they were MAF'less

Once we can go MAFless I plan to make a fitting for the pvc heater connection that can be welded on an aluminum tube. So would need a slight extension off the pure inlet with an aluminum tube, then the filter would be after that. N54 guys have had luck fitting the 335d air scoop which goes to the left side, directing air to the new filter location. But I think it only fits 335, not 135.

I get that, but the cutting and joining aspect is a bit inelegant.

Personally I'd far rather have a complete replacement part over hacking up and clamping OEM plastic parts to alu piping. I suspect the way in which they are joined also sacrifices a small degree of flow smoothness as well.

A complete pipe can't flex. Unlike the E series, the F intake is mounted to the car (the Es is mounted to the top of the motor). When the engine moves under load, there needs to be a way for the intake not to. The stock pipe has a flex section that would need to be replaced by a hump hose or something, which would hinder flow and create a failure point.

That's my explanation.

A bit of results on the stock turbo. I just swapped out the inlet last night and didn't change anything tuning wise. In comparing a few old and new logs, looks like I have gained 0.2psi above 4500rpms. I normally shift at 5200 so dont have anything higher. As a note, I have the stock airbox with K&N drop in. I'll be trying the MAF delete and cone filter as above and see if I can hold more.
