“Really Woke The Dead”
Big Cam IV P/T Pump 315 CumminsAfter the first haul of logs, I immediately noticed a huge gain. This thing is awesome and we have really woke the dead. The motor has never ran so smooth. I'm impressed and will pass on the news to others.Harold W.
The Results Are Amazing
Newmar 2004 Dutch Star with Cummins ISL 400 Engine I installed the AirDog on my Cummins powered motorhome myself. Easy installation in the same location as the OEM single fuel filter. Return fuel line from the AirDog was tapped into the original return fuel line. Again, it was an easy job. The results are amazing. Throttle response was noticeable on first test drive. I no longer get the hesitation in acceleration and hiccups while increasing the demand on the engine. Also better mileage - pre-AirDog was about 6.6 and after AirDog is 7.0+. The engine now performs like a 400hp engine should perform. My only regret is not doing the change over much earlier. Don M. Rockwall, TX
Wish I Would Have Purchased Sooner
Cummins N14 Wish I would have purchased the AirDog sooner! I’ve picked up 0.4 mile per gallon since installing the AirDog. Love your product! Shawn W. Indianapolis, IN

Less Downshift, Less Smoke, More Power, & Improved Mileage
2007 Cummins ISX Right after it was installed, there was an immediate change in the engine performance – less downshifting, less smoke and overall more power. I had to relearn how to drive it with the extra power and my first tank went from 6.87 to 7.41. Even if there was no mileage gain, I had no plans on returning this before the 90 days just for the performance that was gained. Lunch for the AirDog team is on me! Charlie L. Shakopee, MN
No More Downshift & Quiet Engine
No longer have to downshift going up hills in my area. Engine is extremely quiet compared to before the AirDog. Mike L. Nebraska
Should Have Bought an AirDog Years Ago!
I installed the system on my 8.3 Cummins as soon as I got it [November 2020] - had an order to transport 174 car loads of BMWs, so I needed to hit the road. My truck has performed flawlessly, easier cold starting. Runs great and contrary to earlier assumption is definitely getting better fuel mileage. My 4th qtr IFTA return will tell the tale. Should have bought an AirDog years ago! Thanks MT Transportation Mike Tyre
Every Stock System Needs This Upgrade!
Monaco Windsor RV with 8.3L Cummins CAPS I installed the AirDog myself with the help from the AirDog staff on the phone! The AirDog system has fixed my problem which was downrating my engine. My RV definitely runs much better. My RV is powerful again! My SilverLeaf system is already showing a 2 mpg increase with only a couple hundred miles. I replaced my stock lift pump 3 years ago. I wish I had known more about the CAPS fuel system. I would have put the AirDog pump in at that time. Every stock system needs this upgrade! Edward M. Orrville, OH
