[my_little_polo]

hi, can any one out there tell me if there bmc cda has made a difference to there car polo gti and is it worth buying or is there anything else out there which is a good product.

IMHO there is a little bit more pull at the top end of the powerband, seems to respond more freely when you get up there. Other than that it just makes a superb noise

Depends what you mean in terms of "a difference".

If you fit a decent cold air feed then it makes a big difference in terms of noise.

As for performance, hard to say really but it feels more responsive with the BMC fitted that's for sure.
