RS2 Airbox, what an improvement

[s2_bo]

Ditched the A`PEXI cone filter and replaced it with an RS2 Airbox with oem paper filter element.

I was shocked at the improvement, the pull in 2nd gear above 4K is far greater and its now holding 1.3bar to the redline in 2nd, 1.4+bar in 3rd and 1.5bar in 4th and most likely 5th but i haven't tried this yet ever as that would involve breaking the speed limit

The part i took out is this:



and replaced it with this:



The engine bay now looks like this:




The first thing i noticed was the Idle, its felt and sounded smover. Fuel economy was also improved slightly.

All in all im very very chuffed with this upgrade and would recommend it to anyone that is running a stock EM and can fit this big box in.
Cant wait fit the RS2 spec engine to be finished now

I am not at all surprised. Most people seem to junk the cones after a while, due to some if not all of the above reasons...

Glad you like it.

Cheers,

Steve.

Noticed the new clips there bo (looking good) can i assume that the RS2 box is direct replacement for stock & no other tinkering needed.
My car is totaly stock now for 3 yrs & i think its time to start tweeking a few things (Homefries to start) & thought air box as good a place to start as any?.

Yeah, dont see why not. iirc you need a different backplate for the light cluster as the input funnel is so much bigger than S2. Its under £10 though, the part number is on here somewhere.
Apart from that its pretty much a direct fit.

Well well well. +1 to stock filters. I was told by few people about things improved like that. Glad, because I will go for custom made stock replica. Now I am sure - I will not waste my time. Now I am running "green" cone.

Besides there where some tests in "autospeed" site, and they found out the same thing. They did measuresment on S4 AAN with pressure drop. The only thing they improved - cold air in.

Regards,

Yeah the backplate like bo mentions is around the £10 mark as I had one turn up the other day brand new but its not for an rs2 box its something else i'm going to try

I personally run an RS2 airbox in my S2 along with a K&N air filter, works a treat
