This is particular problem in winter climates that also use de-icing salts. Also top heavy metal ones have been reported to cause issues. Lengthy discussion on this in the XF forum a few years back.

On the "blower noise" thread, they mentioned Mina Gallery. I went & took a look and look what they have:
http://www.minagallery.com/mina-gallery-valve-stem-cap-set-red-option/
They also have super reasonable prices on CF parts, I guess because they are just overlays, not the whole part... Think this would look OK or look like crap??

I wouldn't thunk that JLR would have made them aluminum and it appears many on the forum didn't know it was an issue. I should have verified, but I had with the oem growler caps (as I said plastic).

Received Official Growler caps from Jaguar. They are plastic so they should be fine.

I'd use metal ones without giving it a second thought. I don't drive my car in the winter but if I did, a bit of antiseize, grease, vaseline, or almost anything else would solve any potential issue IMO

Recently had my winter tires removed and the tire shop had a helluva time getting the caps off. These were the ones provided by Jaguar NA as a thank you gift which was delivered via courier in a real nice case a couple of months after I had received my car. I remember chuckling when I opened the box as the caps looked very cheap and appeared plastic. I installed them without any anti-sieze and after a winter of snow and salt I'm lucky the shop was able to get them off without breaking the TPMS sensor.

May have been metal. I didn't have an issue with the plastic oem growler caps after 4 winters, but the Union Jack oem ones I bought with the Rover were metal and seized after 2 winters. Need to use anti-siege regardless to be safe.

+1. The growler caps are aluminum and the threads will oxide if you don't use white grease or never seize.

Just received and installed. They are plastic and believe to be trouble free from oxidation after raining season.
