Prosty is RTM, its a company him and his friends have made up I enquired about a box a while ago and am still looking into it once I get thru my mot. He's the guy that posted those two pictures above of the boxes, been looking for the pics for a while to show someone else.

This came up the other week when I was looking over the rally car that the garage looks after. I noticed that Prodrive run a totally standard airbox on the Subaru rally cars and I was surprised. It led to a discussion with my mech. because I'd been thinking of getting a cone filter and he put me off it rapidly, on the grounds that a) it's almost impossible to protect them from heat, b) a well designed feed from the front (which manufacturers do think about) gives a better feed to the intake.
I retained the OE airbox, etc., fitted a K&N panel filter, and removed one piece of rubber strip (which can easily be put back) that runs along the top of the headlight (there's another behind this which seals the engine bay) which opens up a lot more airflow by itself. I get much improved throttle response and no negative effects of hot air, etc.

I use a BMC carbon on my Rover, and it works so much better than a standard airbox or a K&N cone filter. Does anyone have a picture of one of these fitted on an S2 ABY? ts alot cheaper than an RS2 airbox and alot easier to find.

Carbon Dynamic Airboxes ook like a good option.UrS6 - Homefry, Bailey DV, PiperX filter, Samco hoses, H&R springs, 3" D/P back zorst, 270bhp and 260ftlb :rock:

What about getting one of these and using a rangie K&N in it?
You could strip the paint of and take a hacksaw to it and then chrome it to give it some heat resistance ability.
Chop the trumpet off and then add some ducting.
Waddya reckon?UrS6 - Homefry, Bailey DV, PiperX filter, Samco hoses, H&R springs, 3" D/P back zorst, 270bhp and 260ftlb :rock:

Well, people are talking about fitting Carbon Dynamics airboxes to their cars, the Rangie airbox would do exactly the same thing for a hell of a lot less expense!
How is fitting Land Rover parts to a 14 year old Audi taking a step backwards? You don't see many Q7s driving through Borneo or across the Sahara!

But how many NEW Land Rovers do you think would make it through Borneo without self destructing? Don't get me wrong I like Land Rovers, I had a Classic Range Rover for 6 years, but the build quality is truly terrible and there is no way I would fit any Land Rover parts to my Audi. I always thought the RR airbox looked very restrictive anyway, have you seen the size of the air inlet?Well, people are talking about fitting Carbon Dynamics airboxes to their cars, the Rangie airbox would do exactly the same thing for a hell of a lot less expense!

I'm not convinced. It's not made from carbon fibre, which if you believe the BMC info helps to keep the air cool. Also the BMC filter is designed for ultimate performance in a road/race car. The Landrover filter isn't designed with that in mind. Sorry but I don't quite see your logic. Your S6 Airbox is already of better design than an S2 box because of it's cold air feed, as AndyP has already stated!! I'm prepared to be proved wrong though.'93 S4 Avant now back on the road complete with new shiny go faster bits.Comment

I am talking in general terms, not as a mod for my S6.
Carbon fibre has a higher thermal conductivity than normal carbon steel, so no, the carbon fibre ones don't insulate better.
If you chrome or insulate the steel rangie one then it should keep the air nice and cool. Compared to a BMC one, and they don't cost £150 either.
Will be keeping my S6 box standard, its just an idea for those thinking about an airbox mod.UrS6 - Homefry, Bailey DV, PiperX filter, Samco hoses, H&R springs, 3" D/P back zorst, 270bhp and 260ftlb :rock:

Tbh, think that on the s2 best set up would be either a RTM box or RS2 as the cone just gets soaked in heat unless alot of work was done to protect it which could limit the airflow, only advantage is there is a bit more noise from a cone.Comment

I think there is nothing wrong with the stock aby/rs2 box, cool air from behind the gril and a good design.
And I Like the sound and performance of my aby box on my 3b s2.Comment
