Fits perfectly. Engine runs more easily/smoothly and slight increase in mpg as well.

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.
