Cat C15 with Regen My truck performs like never before since installing the AirDog system. Now I have plenty of power and I am able to pull my oversized loads during regen cycle with ease. The AirDog system does exactly what they told me it would! My truck and typical load is 50 meter blade grossing just under 95,000 lbs. Alex D. Chapin, SC

I installed the AirDog and right away the engine [Cat C15] was smoother. My fuel mileage went from 5 to 5.8 mpg. I run the same route every day, so there aren’t any other factors that would have affected the fuel mileage. I am very pleased with the quality of the AirDog system. Best of all, it’s made in the USA. Jason H. Wooster, OH

Installed an AirDog on my 2006 Single Turbocharged ACERT this week. -10° to 30° above zero had absolutely no effect on my typically finicky engine. Unbelievable improvement in all around performance. While I fully suggest keeping up on all bypasses and filters in a stock system for peak performance, this system is a no brainer for reliability and consistent performance from your Caterpillar engine. I’m beyond impressed with performance and also the ease of installation. Quality second to none! Anthony Cain LA Transportation Services Fairfax, VT

2003 379 Peterbilt Caterpillar Thank you for the fast delivery, and the tech and secretary I talked to were both very helpful. I have it installed on my truck and man, the difference that it makes at an idle. Can’t wait to see what it does driving down the road. Thank you. Michael McAllister Great Bend, KS

AirDog installation was a breeze and I can feel power gains in my truck. Just getting through my first tanks of fuel and will be checking fuel mileage. Thank you for the fast service and awesome product. Mitch Anderson Trucking LLC Dayton, IA
