My Countryman All4 S runs great with tese plugs. They use a common 5/8" socket to install. You will still need something special to take out the factory Beru plugs. I used the Long Reach Bi-Hex tool for that duty.
The go to place for mini accessories. They have everything and its all shipped from in the USA. My favorite site I am o it daily and people always ask where do I find this stuff. Outmotoring.com of course!

I have 2009 JCW (R56) and have done a lot of work on it...and unfortunately it needs a lot of work as a cost for the fun.
I am local to Outmotoring and I am very thankful they are so responsive. They can often get parts same day and the prices are very competitive to the big online retailers and ebay. They have gotten me out of a jam more than once...and I can return parts that I did not need.
I have visited them numerous times and they have a nice showroom and top-notch operation. Very friendly and knowledgeable.
