Older 7.3 Deisel vs. Newer Ford Engines

sure, go buy a $50,000.00 pickup and pay the 6% tax and liscense on it and it will pass every 7.3 out there. Or here's one better. Buy airbags, paint it, put a different differential and transmission like a 6 speed, put new leather seats and better insulatiion in the floors and firewall, new carpet, and keep it. You'll have a slow $25,000 pickup. Everything is about getting to the campground first these days. My 7.3 just wore out and i had to sell it. We haul trailers and the diffeential was howling so I decided it was time for newer eqp.
Washed and treated properly, by letting the oil dry, a K&N will be fine. Have used them for 15 years and lived in AZ, CA and NM.
