I have read that 'cold air intake kits' can help improve fuel efficiency, BUT they work best like a turbo at around the 3000rpm mark.
I have tested this, and with my intrepid (2.7l, K&N FIPK, Borla Muffler, no a/c, etc..) 3000rpm is roughly 160KM/H.
Now understand, at this RPM, I was averaging around 600kms to a tank, but that was strictly highway driving (obviously) on premium fuel and I don't think its that bad considering the speed. BUT Please keep in mind, Radar detectors ARE NOT illegal in Saskatchewan, but weigh the options as well, is it worth getting better mileage if it could land you in jail? or worse killed in an accident?
Just some food for thought.
