Today's job has been to fit The Arc Super Intake Chamber.  Easy to do, using all the old bolts and fittings. Makes a lovely sounds! You can hear the turbo sucking air in, and the recirculation valve is louder than any box I've heard. It also improved throttle response slightly and had smoothed out the boost coming on. Well worth the money!

Where did you get the part from @TomB

I think it was http://www.japperformanceparts.co.uk but i can't really remember as I bought so many birds at once from all over. 

It works beautifully. No issues with running rich due to no bov, no heat soak as it's drawing air from the original place, and it makes a beautiful sound.

Play these videos loud, preferably through headphones!
