I have for sale a SSTT that came off my 335xi. There was honestly a night and day difference with this mod and the best part was how easy it is to take on and off! Literally takes a minute and doesn't mess with other parts of your engine that dealers can detect. I never once had an issue with the dealer saying anything and I would remove it right before service and pop it back on after leaving!
I am looking for $110 shipped via USPS priority mail or $100 picked up OBO. Thanks and PLEASE PM ME!
