I have just had my 10K Oil Change and Maintenance check FREE at the dealer where I bought my xB. While I was there, I asked what the cost was to install the TRD CAI. They quoted me two hours at $114.00 per hour. So, just for comparison, I e-mailed another Dealer about the same distance from my home but in the opposite direction and they quoted me $75.00. I called to make an appointment to have them install it and asked the Service Manager what the cost was and he also quoted me $75.00. Seeing as how I bought the unit at the end of November and the warranty is better if a dealer does the install (date of installation rather than date of purchase if installed by someone else) I am going to let them do it. Install day is Tuesday. Can't wait.
