RESTORE DIESEL INJECTORS
RESTORE DIESEL INJECTORS
CLEAN INJECTORS
• Rapidly removes internal diesel injector deposits (IDID) and carbon build-up from injector tips
• Ensures correct injector spray patterns, resulting in a more complete combustion and lower emissions for optimized performance
REMOVE TURBO DEPOSITS
• Clears the turbine and variable vanes of soot and carbon, reducing turbo lag and restoring boost
• Prevents the accumulation of carbon to reduce excess heat and wear, avoiding premature failure of the turbo
REDUCE DPF DEPOSITS
• Improves combustion to reduce carbon, soot and particulate exhaust emissions
• Removes soot and heavy carbon deposits from the DPF
• Reduces regen frequency
• Prevents performance loss and potential engine damage from a clogged DPF

I put a bottle in a tank of old diesel fuel in an E350 (370k miles) that had been sitting for a year. It ran for a few miles then must have picked up algae and started running rough. After changing the fuel filter and adding the AR6400-D it’s cleared right up and continued to run really well. I’m about 200miles in now with topped off fresh fuel still running good.

I have a stock 2009 6.7 Cummins with 85k miles. for the past year my mpg has been decreasing little by little The best mpg was 12.5. I used one treatment of the AR 6400-D diesel fuel system cleaner. It took about two hundred miles before I noticed any change. Happy to inform you all that my mpg increased to 19.6. Very satisfied with this product!!

Smoothed my idle out a little bit. My truck never had cold start issues and I've heard that's where you notice it the most. Decent product for 20$

2002 5.9 liter 24 valve, 150,000 miles. Throttling during idling. This symptom has persisted even after treating the fuel with injector cleaners.
After using two treatments of AR6400-D that idle throttling has subsided.
This saves me from pulling the valve cover and removing the injectors for cleaning or replacement.
This is a positive result in my book.
