This combo seems to yield best fuel mileage and performance gain.
My favorite is CAT back exhaust and K & N filter (not intake, just filter).
We each have our own opinions and preferences. This allows a K&N cold air intake system to boost performance, by simply improving on the factory design.I have been using K & N filters, installing Cold Air Intakes, CAT back exhausts for over 30 years now. Does cold air intake add HP?Ĭold air intake systems can increase horsepower by replacing the restrictive stock intake, with components that are designed to handle a much larger volume of air. Will a short ram intake void my warranty? This increased complexity also leads to a more difficult and time-consuming installation. However, since it is longer and more requires more complex routing, it is often more expensive. The cold air intake does typically get denser air than the stock intake. That means more airflow, which, combined with the cooler temperature, means more oxygen and more power. In addition, oftentimes the cold-air intake filter is wider, with a less-restrictive material, than the OEM one. Is a bigger cold air intake better?įor one, the factory air intake design limits how much oxygen gets into the combustion chamber. In any meaningful instance, a short ram will lose power. If you are like most performance enthusiasts and take advantage of the additional horsepower by driving harder, you will not see much of an increase in MPG, if any at all.” Does short ram intake lose power?Īt high speed, you’ve lost the tiny bit of ram air effect that the stock box gives If you’re after power, the shorty is not the way to go. Less restrictive air passageways such as an Injen air intake can provide more efficient combustion. Switching to a K&N filter is an effortless method of increasing gas mileage. This helps increase fuel economy as well as offer your vehicle more gains in horsepower. Unlike your typical air filter, K&N air filters allow more air into your engine. Almost by definition, idling is a waste of gas. A common cause of poor mileage is inconsistent speed. How can I get better gas mileage in my truck?
