Your concern should be about the disadvantages. They more that outweigh the advantages.
New airbox, piping, and oiled filter. Cool. You might have just added 5-10 hp. But at what expense?Oiled filters are designed to increase airflow. They do. That is great on NASCAR and death on...
Just gave my dealer my H8 DieHard and H8 binky. The dealer wanted 449 for the Motorcraft batteriyi. I saved 200, less whatever they will charge to chain hoist it up and connect it.
I am replacing my 21 battery because it is showing at 56% life left. My understanding is that anything below 75 to 80% life becomes a problem with over the air updates. I am behind in over the air updates and that may be why. Or maybe not.
Back in 1974 my points were not drawing anything when the ignition was off. Today, courtesy of congress and the EPA, we drain batteries. If it were not for government regs requiring the use of computers to meet them, I wouldn't have my 2010 Cadillac CTS V or my 2018 Corvette Z06. I may not be...
Having zero experience in this matter qualifies me to throw an opinion out there.
1. How will you be using this truck?
2. Is the gear oil synthetic?
I like the thought of more protection offered by the 75-90, but would not run the 140 unless you are really thrashing that rear end. Heavy...
The wife disagrees with the fart weight. She thinks it may have something to do with diet. More donuts the lighter the fart weight. Maybe a fart video is in order.
Get that front end aligned by a Ford dealer with late model equipment. You should not pay for that. Get before and after alignment sheets. That should straighten out the steering wheel. Get someone to follow you to check tracking. If this doesn't work the insurance company needs to know...
The beauty of electronics. Didn't have them in the old days. Now we do in spades. Hundreds if not 1000's more things to go wrong as a result of all the additional parts/circuit boards. Beats the days of three on the tree, no power steering, and twin I-beam front ends.
Plastic is much more susceptible to failure in temperature extremes. If you are garaged in Tampa you may be OK. If you want to keep that truck 15 years, there may be some problems. When cars were moving more to leather in the 70's and 80's the old stiffening and splitting of upholstery was...
I bought mine for an H8, just haven't bought the battery. Since the factory battery has one I assume it is insulation from the underhood heat. If that is not the answer I have no clue.
