Have a 2.0 turbo diesel Zafira, poped in KN panel filter (33-2787) and felt difference straight away. The engine can now breathe so it is more responsive, as a guess as to power gain from this filter I would put at 3-4 hp.

This is the first time I tried a K&N filter and I can say that improved a lot. Arrived very quick, very well packed and I will definitely buy more K&N products.
