Just awesome! K&N filters rule.

I have a Land Rover discovery 2004 and have always suffered with it hanging back until the rev counter reached the 1500 mark. I was advised to install a K&N air filter, and what a difference. The whole performance across the range showing improvement.

Instantly noticeable difference when I installed the K&N in my TD5 Discovery. The most improvement in performance compared to all the other K&N's I've had in varying cars over the years. Wouldn't own a car without one. Never had problems with them (one of our cars had just over 250,000km, V8 petrol/lpg, 4x4 used offroad and on), always service them as per K&N's recommendations. Can't go wrong with one.
