I am very pleased with my purchase, the car feels more responsive after fitting the K&N panel filter. It was very easy to fit, even for an idiot like me.

I have had a K&N flat replacement filter in my BMW 123d (and another in my wife's petrol powered Peugeot 207CC) for some two years now, and would not be without one. There are three benefits I've noticed in the BMW: 1) Better fuel economy 2) More power 3) A lovely engine grumble in city driving. I would recommend K&N for any vehicle.

This performance air filter has drastically changed the acceleration on my BMW 330d. I had a full remap 6 months ago, and with the new air filter, the engine can finally suck in the air it needs to. I will replace the air filter on every car I buy now. Thank you
