I know the MAF sensor/assembly is different.

I'm not sure if the RS airbox/induction tubing would successfully mate to the ST MAF sensor, as I do not believe you could fit an RS MAF to an ST.

However, I am WAY beyond my "comfort level", and am pretty much guessing.......

I think it would have to be, how do I put it? "Bastardised"

A bodge job of the highest order.

Or I may be lying

I wouldn't be so quick to fit an
airbox to the
as a lot of guys on focusRSoc are complaning that the rs airbox design is flawed and very restrictive, you would probably be alot better off with a DSCi induction kit or similar.

The Outlet on the RS airbox is at 90 degrees to where you'd need to line up with the ST MAF if you were still going with the standard layout for the cold air feed pipe into the turbo. In theory you could cut a hole into the RS airbox (if it fits into the car ok) but you'd also then have to modify the internals to get the new outlet fed by filtered air. The filter in the RS airbox forms the end of the airbox so it's not that simple to move the filter about.

May be easier if you were to re-position the MAF along the lines of where it gets moved to when you run the DS induction kit but the cable may not reach once the RS airbox is also in place plus you'd need to redesign the cold air pipe from the airbox to the turbo unless the one from the DS kit would do.

Bearign in mind the airbox set-up on the RS isn't ideal anyway you could do all this work then find you need t ocut loads of vents in the airbox or leave the lid off which defeats the object imho.

You'd probably have to buy the RS pipe to the turbo as well. The MAF sensor would be ok in that position as it sits in that position when mated to the DS Induction kit. That means you wouldn't have to cut the airbox up

I think room would be tight to squeeze the ST MAF assembly in between the RS induction pipe and the airbox as you'd need space for hoses to join it all up. There is say a 45 degree bend to make up too if you look at a photo of the RS set-up. And you'd need to do some work at the other end of the RS cold pipe fitting into the turbo inlet pipe as it's different than that on the ST and could need adaptors etc.



Better to forget the RS airbox and run an open filter off the end of the RS induction pipes I'd say if you go to the effort of using the RS Cold Air pipe.

When I did my set-up running the modded K&N and RS ECU cover the next step could be to go to the RS induction pipe, mount the MAF on the end of it then Samco onto my existing pipework keeping the filter down behind the bumper but I spent enough time and effort getting it how it is now. The Samco pipes and big hose clips soon start costing money and I'd need a 45 degree bend as well as the RS pipe, adapting it to match the turbo inlet rubber pipe and sorting out a blank for the RS MAF on the inlet pipe.

Also have to blank off the plug connection. I don't think it would give any gains mate. You have removed the main restrictions by getting rid of the main airbox and getting rid of the box on the K&N

WOW, thanks fellas.
I was going to buy the modified RS airbox from Pumabuild for £99 including Pipercross Filter and fit the existing St pipework using Samco or Mandrel Bent stainless pipework to it. I know the engine bay design allows the room to fit it and I would require the RS airflow panel as it is on the other side to the ST.

I am reluctant to go down the DSCi route as I often have to drive through deep puddles up the driveway to work. I also like the OE+ approach.

Any obvious problems with this plan???

What about the Autospecialists one if deep puddles are an issue matey?

Thanks Chris, I had looked at these.
I think I will just have to go for it and give the RS box a go! If I do it it will be after Xmas, I will take photo's and post if it's a success, If it turns out to be a balls up .......I'll keep my head down!!

Reckon you'll have some tricky work to do getting a pipe from the ST MAF into the RS airbox but you could always shorten the hose between the cold air pipe and MAF itself to give yourself some more room.

Is your ST a facelift? airflow panel off the RS won't fit the pre-facelift without some modding.

You will need more than this mate, I think the Pumabuild kit is the airbox lid only not the complete box..

+1 it is just the lid, I would just buy the Dsci kit, much eaiser to do, or if your worried about the low air intake, get the GGR/CD:RED/Autospecialists one.
Thier all really good, just depends what kind of noises you want the system to make.

We have been looking into this as well, the only thing we have noticed that may cause a problem is the battery box is different on the rs as well as all the brake servo hoses. So you would need to re allocate all these as well. And knowing the valve on the front of the battery cost £70 on its own you can safely say the rest of it wont be very cheap.

As others have said if you can do it then go for it but i wouldnt rush into things too quickly. Youll end up with a load of parts that you cant use and no one else wants. I know cos i have a whole garage full of spare st parts.
