If you look at the picture I posted up you can see that that bit of pipe is used to connect the OE piping to the Elbow (BMC) piping...

Kai, honestly, I'd live with the car as is for a month or so before you start modifying it... I mean you're used to the 120 and the 180 is quite a bit more power as is... But at the end of the day up to you!

worked fine on mine for over a year :whistle:

i deff will work fine on mine!!!:shoot:

Mine did too... then started having issues... :)

Wonder why?? Was the filter for the idle maybe clogged up? I know the wee ane i had on the black zed got dirty fairly quickly but never had any running problems:)

was a halfrauds special... probablt more to do with that... lol

Mine was a Pipercross and seemed ok, the guy that bought the whole set up off me hasn't had any problems since either

...

Strange... maybe the filter I had fitted was either faulty or blocked or something... certainly wasn't doing its jobs correctly by the sounds of it!

My BMC CDA and breather have been fitted for around 5 years now with no issues. I have also had it remapped with this fitted with no ill effects. Pipe size iirc is 19mm bore. My IACV was playing up on Friday, just needed stripping, cleaning and re-assembling carefully as the rpm was hunting, all's good now.
