Adding a cold air intakes moves the air filter to a colder zone inside of the engine compartment so that cooler air can be sucked into the engine for combustion. Cooler air brings more oxygen (denser air) into the combustion chamber and that means more power. The filters are usually moved to the upper wheel well area or near a fender where there is more access to free flowing, cooler air and less hot air from the engine. Combining a cold air intake with an HPTuners custom tune means your engine can use that air more efficiently to produce more horsepower and torque.

Not only does a cold air intake reduce the air temperature, but it also increases airflow, which we can use to enhance your engines natural ability to produce horsepower across the entire powerband using HPTuners. Aftermarket intakes remove the need for a box surrounding the air filter and instead use large diameter intake tubes that are smoother, have less bends and are often wider than the original factory ones. Removing the air box and using smoother tubes gives the engine uninterrupted airflow.

An aftermarket performance exhaust can free some of the power in your engine. These systems allow for a quicker, more efficient path for exhaust gases to escape. This means your engine “breathes” better, so spent fuel and air exit the combustion chambers faster. That means more fuel and air can be burned to create more power.

There are several other good reasons to add an aftermarket exhaust system. One of the most noticeable is the subtle, but distinctly aggressive, change in exhaust note. Many of the better systems are only slightly louder than your stock exhaust at idle, but they deepen to a low “growl” during acceleration.
