Cold Air Intakes & High Flow Filters
Keeping Your Cool
More Air = More Power!
Power output is a result of an exploding air/fuel mixture. Thus, it is sensible to think that by giving your truck the ability to suck in more air in to the combustion chamber, you can create a more powerful explosion.
With better air flow, your vehicle sensors will tell the ECU to add more fuel to keep air/fuel ratio optimized for maximum combustion.
In other words, a cold air intake increases air flow to the cylinder by having a better flow rate and also by utilizing \"cold air\" (air that hasn\'t been preheated by the engine bay).
Remember the old saying \"heat rises\"? That is because hot air is less dense than cooler air. That is why your truck feels less powerful on those hot days compared to those cold January mornings...your engine can\'t force as much as into the combustion chamber on hot days as it can on cold days.
Another benefit of cooler air going in to the combustion chamber is that the exhaust gas (post combustion) will also be cooler (colder to start with, it ends combustion cooler).
When you \"chip\" your vehicle, you increase the exhaust gas temperature which can be dangerous to certain component in your transmission and engine. Therefore, a Cold Air Intake can have dramatic, positive effects on EGT and engine longevity.
With a 110 hp upgrade through an ECU reprogramming, expect your EGT to rise approx. 200-300 degrees (obviously, it will depend on many factors like load, outside air temp, altitude, etc.).
By bringing cooler air into the combustion chamber, a cold air intake can reduce the EGT by aprox. 100 degrees.
Translating all this into horsepower...expect 9-15 hp and up to 34 ft-lbs of torque depending on the application.
