Scotty Air Systems
Frequently Asked Questions
Scotty Air
Will the Scotty Air system benefit my truck?
The Scotty Air System is designed for the working truck in mind - if you have done some power upgrades to your truck and use it to haul a heavy load, or for racing. The Scotty Air System will help your truck deliver its available power more readily by reducing the exhaust gas temperatures or keeping them in a safe range while working the engine. Stock trucks may or may not see benefits from the Scotty Air System.
 
Besides reduced exhaust gas temperatures, what else can I expect?
Several individuals have reported better throttle response, better mileage, and virtual elimination of the ‘seepage’ of dirt like with the factory air box, due to the superior seal of the Scotty Air System.
 
Will the Scotty Air System alter the sound in the cab of my truck?
Yes, the sound will change. The Scotty Air System is optimizing the air intake of your Cummins engine by taking air from the positive air pressure area below the windshield. You will know it is working effectively under load by the increase in air intake noise. A very small percentage of individuals have sensitive hearing to certain pitches of sound; caution is advised if this is your situation. Like many alterations and changes done to any vehicle, operating characteristics and sound changes will happen.
 
Are there any other filters besides the K&N RE:0880 filter available for this application?
Yes. Besides the K&N RE:0880 you now can use the AFE #20-40044 with internal velocity stack. Testing has shown that the AFE filter is giving another 50F reduction in exhaust gas temperatures.
 
Is the K&N filter safe on my Cummins engine?
Yes it is. So far anyone that has reported their oil analysis to us has noted that the silicon (dirt) levels are very low even on highly modified engines.
 
What about getting snow or rain inside the engine with this application?
Several tests have been conducted. A pressure wash spray nozzle was held at the base of the windshield forcing high pressure water at the Scotty Air System. No measurable amounts of moisture were found and no damage was sustained from this test. Not many people aim a high pressure spray of water at their air intake system while the engine is running no matter what the condition - we did, and the result was excellent. The Scotty Air System proved to be well protected from rain in its position.
 
With the Scotty Air System, you can still start your truck safely while the air intakes are covered with snow. A provision was taken into consideration at the end of the Scotty Air System nearest the turbo inlet. It has a small space around the air intake here to allow some air to pass while you get the snow off your vehicle.
 
Will altering the Scotty Air System help make it more effective or efficient?
No. Many variations of the Scotty Air System were tried and tested by our research and development team. Even the slightest deviation from the rigid specifications showed diminished performance. Caution: do not seal off the end nearest the turbo inlet hose in attempt to capture more cooler ambient air from the induction point. Air filter collapse can and will occur. Any alterations or changes made to the Scotty Air System will void any and all warranties.
