And it also lasts forever. There was one in my dad's work truck that was over loaded with tools and part 24/7. It was driven 98% in Baltimore City, and driven hard. Not a single issue up to 100,000 miles. Idled and ran smoother than a brand new 4.0. But then it was sold and replaced with another but I'm still impressed.
I DO LOVE MY 4.0 so don't get mad!
