Anything to increase Fuel Efficiency? Are they worth it? Cooler Kits?
Recently bought a 2015 370z Sport Package, really excited!
I want to invest in modifications, but I am only interested in the ones that increase fuel efficiency.
Been doing some research and found some cool stuff! Cold air intakes, Stillen transmission cooler kit [my 370z is an automatic :-) my daily driver car], as well as other coolers kits.
Do these things increase fuel efficiency? Performance?
Thanks!
