RS4 MAF Modification

[Ross]

Sounds painful

So the element and electrical connector is one piece you buy from Bosch, and a simple swap into the MAF housing by the looks of things. Hmmmm, I looked into a batch of 10 housings, they want 250 bucks shipping, anyone off th china any time soon

Is this the B5 RS4 MAF you're talking about using, part number 0280218067?

Yeah, but get the exchange version 0 986 something.

I was looking at that one, never quite sure that the stuff you get off Ebay is genuine Bosch though. I've been quoted £130 for a new one ( not the exchange one ) today from a real Bosch dealer.

wow, thats good...most places I checked couldn't get one for at least 2 months and it was over £170...

I've got a mate who's back and forth to China all the time

You don't need the electrical connector, I got like 6 of them.
As I have said before, I'll take care of all the electronics work. You wouldn't know where to fit what anyway

The element from Bosch... I need to find the exact part number for the sensor.
Also, what AndyP quoted is more in line with what it should cost.

What did Sonic go for in the end. The full RS4 Maf in it's large 87mm housing or another smaller housing with an RS4 element?

I'm attempting to make up a new inlet pipe and need to ensure I get the right size silicone joiners.

Full MAF, and he got a custom silicone maf-turbo hose made up, so it all fits nicely.
The RS4 MAF actually fits into the stock airbox if you mod the airbox somewhat.

[Sonic]

Full rs4 maf directly into the rs2 airbox which was ground down a few mm to ensure a perfect fit. The maf is sealed into the airbox to ensure there are no leaks, and then finished off with a roose motorsport hose which was made for the job

Dmitri then wired in a new plug and did the necessary ECU mods to work.

and is good enough the RS2 airbox with +450Hp?

because in the past i sold my RS2 airbox because i had to fi a RS4 Maf

The Roose hose sounds like the way to go, however was it made for the ABY pipe locations or it it just a straight through pipe from the turbo inlet to Maf housing? I can see my original Maf hose has a takeoff for the WGFV, the BOV return and the Crankcase breather hose inlet.

It has all those too.

It looks like my RS4 Maf has failed. Does anyone have the Bosch number for the sensor insert?? If I can get the sensor, I'm hoping it will be a lot cheaper than the whole Maf.
