I just refitted my stock airbox after about a month with DCI's and I think the stock box is better.

It felt like the DCI power delivery was smoother, but the stock air box feels like it pulls harder at lower RPM. Maybe it's all in my head, but I think I like the stock airbox better.

The 'sound' of cone filters doesn't do much for me, and the fact that as soon as you lift the bonnet the authorities and can point at it and know it's illegal... I think I'll keep my stock air box now.

Edit: I forgot to mention that I'm not running any upgraded intercooler - maybe with an intercooler the limiting component might be the stock air box, but I don't know.
