Do Not DPF Delete Logo

John Henry


Truck Driver

I am John Henry, a long time tuck driver and mechanic experienced in cross country hauling. I have seen first hand the effects of diesel trucks on the environment and so I’ve tried my best to lessen those effects with my own heavy duty vehicles.

I created this site to help everyone understand the importance of clean emissions and how important the DPF is towards ensuring clean emissions. I explore topics like improving the performance of your DPF and avoiding DPF delete.

I hope you’ll learn something new here to improve your exhaust system as well as avoid EPA penalties. If you have any questions, be sure to contact me at
