I have had this for the last year and we just put up the 335 for sale. This is for the N54 powered BMW's. Retail price is $279 so save a ton with this gently used one. No issues and makes a huge difference on the car! You cant go wrong with this when on a budget. If you have any other questions PM me or checkout information on the JB+ at
