Review on ๐Ÿ”ง Dorman 598-114 Exhaust Gas Recirculation Tube: Enhancing Engine Performance by Mayrando Clark

Revainrating 5 out of 5

My gas mileage increased a good 3mpg

Electrical part aside, this made a big difference to my 7.3 liter diesel. My gas mileage has increased by 3 mpg. This is definitely a maintenance that needs to be done every few years. My tube was so clogged with dirt I couldn't even blow air through it.

Pros
  • Best
Cons
  • Ease of maintenance
