Would be great to get a review from you about the car for a family and pros and cons etc. looking to pull the trigger on one of these but not sure about the m40i or the M60i
Made a quick video for you. Let me know if you had any specific questions ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-JPusVRwz7Vg.htmlsi=5f4DCCTLAAM4qpaf
Honestly I don’t think it helps or hurts. Def not anything wind tested. I get about 20-21 mpg primarily city driving and mostly in eco mode. Didn’t change after adding splitter. I drive fairly quick but don’t have a lead foot. Got heavy popo in my area and they love to pull people over
