Why did you order the O2 spacer if you didn’t know it would fit?

CTS has been building and designing products for german vehicles for a long time. If you ordered the wrong product pay the restocking fee and suck it up. If what you ordered was correct for your vehicle and there was a manufacturer design flaw they will take care of you. I feel as though you have provided only 10% of the story.....

CTS has built a business on ripping off products from their competitors. There is a reason their stuff is so much cheaper and generally of lower quality.
