I installed this over the weekend. I had to remove the door, which was actually pretty easy compared to my 97 Defender. I will say that this raised air intake is the cheapest feeling piece of gear that I have ever fitted to a land rover. It does not feel like a quality piece at all. The cap would flap in the wind and most likely be lost driving down the highway, but adding a little 3M moulding trim tape in the right spots made it solid enough. After it was all mounted it seems durable enough, but it's not what you'd expect from a land rover OEM part.
