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!
