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
Fuel Mileage Increase
AirDog was installed myself on 379 Peterbilt with Cat C15 engine. I have seen about .5 mpg increase in fuel mileage on the road. Ben Peck Keota, IA
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
Works Flawlessly
2002 Itasca Horizon RV with Cat 3126B Engine All is great with the fuel system. I have not heard of many people installing the AirDog system on the diesel pusher RV units. However, I think it works flawlessly. I have not put an enormous amount of miles on my unit after installation, but a few thousands of miles I have. So far so good. I also installed a programmer for the Cat 3126B engine.... which is conjunction with the AirDog system has given me more power and ease of mind. I like the combination a lot.

30,000 Miles Out of a Fuel Filter
Cat 3406E Idle quality is much smoother, plus the engine makes much more power from idle all the way to red line. The mileage has gone up .6 to .7 as an average and I see 30,000 miles out of a fuel filter. Love this product! Tom Rauer Waconia, MN
