It's worth the extra $$...IMO.
I run AMSOIL synthetic oils in my engine, rear diff and transmission. I've also I stalled the S&B CAI and a Magnaflow exhaust. I have the 3.55 gears and run only 89 octane gas. I hand calculated it and read 19.5MPG on the EVIC my last long trip.
Not to get off topic, but you like the S&B over the KNN?
