be careful buying filters from WW, they do have some counterfeit filters. if they are $0.75 or so less then you are probably ok, but $3 or $4 less I would stay clear.
very true, when I worked at Ford and the 5.4 went to VVT they had a lot of problems with Fram filters coming apart and plugging the oil passages in the cylinder heads. I would stick with what Ford put on it, at least until its out of warranty. but I would NEVER use a Fram filter. there are...
something else to keep in mine that even though the octane may be the same, 91, different brands have different additive packages so they can give better mileage and performance
you are assuming that the stock fuel injectors can supply enough fuel. 2nd its not spark knock that is dangerous to turbo engines its detonation that causes the damage which has nothing to do with spark timing. the stock fuel system will keep the 14.7:1 to get more power out of E85 it would...
what I have on mine is coolant temp, transmission temp, CAT temp, absolute fuel pressure, LT FUEL trim and ST FUEL trim. This allows me to know that I'm running at the correct fuel mixture and that the Engine and Transmission aren't getting too hot.
Likes: the power, fuel economy, the handling off road (with the Ford/fox upgrade)
Dislikes: the placement of the lights on the HVAC system, they seam like they should be above the floor/dash'/defrost buttons
I routed the wire up the A pillar so I can mount the pro cal when towing or going off road to monitor Transmission, Engine and Cat temps. Other than that it is in the glove box
higher octane doesn't mean more energy, or BTU's, per gallon. higher octane only means it burns a little slower so it allows the ignition timing to be advanced and that keeps the spark knock down
