S2 MAF RS2 Box

[Big_kev]

Guys

Is the S2 3b maf able to fit into the RS2 airbox in any way. I don't know if there is an adapter plate or something that i could use.

It's a direct fit. I've used the ABY MAF on an RS2 airbox no problems.

Sorry for being completely daft but does anyone have a picture. It would appear that the fastening lugs etc don't match up. Will have another look tomorrow maybe just not seeing it at the moment.

Im going down the same route, remember reading a post about widening the fixing holes slightly or something not much help I know but will be interested in the result

I'll take a pic of mine, I seem to remember I had to use a couple of washers to clamp the 3B MAF to the RS2 airbox..

Cool would be good to check this as I want to sort out fitting one at some point soon

The way mine is done the bolts and washers just clamp the 3B MAF alongside the original fixings, this places the MAF at a nice flat angle to the top of the box too. Its been absolutely fine like this for ages and was done exactly the same way before when I had the ABY box on there.

That looks normal to me. It is certainly how my ABY one was fitted and my RS2 one is now fitted.

So if the S2 Maf fits to the Rs2 airbox then does that mean that the Rs2 Maf fits onto the S2 ABY airbox? The resone i ask is becuase last time i cheaked the Rs2 Maf was cheaper than the S2 ABY part.

Yes, I ran the S2 MAF connected to an RS2 airbox for about 6 months before I acquired an RS2 MAF. I also bolted up the RS2 MAF to the S2 airbox as a trial, before fitting.

The S2 and RS2 MAF's are identical in all dimensions (both ID and OD) and therefore so are the airbox fittings for the MAF. The only real physical difference seems to be the mesh gauze on the S2 is replaced by a plastic grid on the RS2, which according to a US guy who flow tested all the components in the induction system, produces much less air resistance than the mesh.

Fitted 3b MAf to RS2 airbox as described and fits great. Just used washers as well and forgot about the original mounts.

I'm about to buy an RS2 'box, but was led to believe that my 3B MAF would not fit. The explanation made sense: the whole reason for shelling out for an RS2 box is that the inlet/outlet ports on the box are much bigger.

So how does the 3B MAF, which is designed to fit/seal onto a smaller hole, fit onto a bigger one without leaving a big gap? I'd rather not have to buy a MAF too, if the 3B one will fit...

Its to do with the actual size of the hole letting the air into the airbox, not the exit...
as this is also restricted by all the rest of the hoses...
I also believe there is a small difference in capacity of the box too, but its mostly the intake bit..... different design and size..... ESPECIALLY when you compare it to the 3B one....
