I have an air box lid from a P38 Range Rover here, and the part number on it is PHB102260. This is the one that quite a few people are using, but when the number is fed into MicroCat it comes up as a complete P38 air filter box assembly.

Most people have also found that you can stretch the D2 trunk onto the new MAF by dipping it into hot water first, since the outside diameter is only 3mm more for the larger MAF.

MicroCat lists PHC000110 as being the correct part number for the NAS 4.6 Disco 2 air filter box lid as a separate component, with a retail price of 53 UK Pounds Sterling. The matching inlet trunk is listed as PHD000480, with a price tag of 57 UK Pounds Sterling. On Monday I'll see if it is actually possible to buy them over here. Otherwise a good USA breaker would be fine, and probably cheaper too.

Well it's Monday here, so I checked the prices as promised. They are available, but only direct from Land Rover.

However the prices are a rather eye-watering price tag of 112 UK Pounds Sterling PHC000110 for the NAS 4.6 Disco 2 air filter box lid, and 75 UK Pounds Sterling for the matching inlet trunk PHD000480.

Suddenly a used P38 lid at around ?30 and a bowl of very hot water look like a bargain! :-D
