MAF to air box O-ring
Can anyone tell me the correct part number and/or size for the larger 2003-2004 intake o-ring that goes between the maf housing and the air box lid? I'd like to hear that it's a semi-standard size so that I can find it in town.

That looks like the part but it's maybe larger for the later models. However, any nitrile O ring of the same diameter and cross section thickness will suffice but remember to lightly smear it with rubber grease on the outside area before pushing the MAF home into it. You can also lightly smear the internal MAF shoulder also.

Happy that i came across this thread. I was shopping for bolts & Orings at a local hardware store last month and stocked Orings in sizes teeny-tiny to massive. Will go buy a replacement for mine tomorrow! Just what I need to finish off a costly top-end rebuild. If you have access to a caliper then you would be able to order a generic by its dimension online. The rovers north.com website should have the O-ring and part#

This is the 4.0 O-ring but the seller, Buckhorn will most likely stock the 4.6 version. Just email them via eBay link and ask about it.

If it's urgent I guess any quality old fashioned engineering store or failing that online from China (sorry Mr Trump 
) where you can buy a selection box of around 20 to 50 O rings. It depends how quick you need them.
