Engine Tuning

Are you looking to unleash the true power potential of your engine? An engine tune is one of the best ways to improve the performance of your motor, a necessity if you plan to upgrade any of your factory engine parts to aftermarket performance parts. Anytime you add new performance parts, it’s critical that you adjust your engines tuning parameters to account for the changes to the air/fuel mixture. A handheld tuner is a perfect solution as it allows you to re-tune your ride to new parameters every time you swap in a new part.

At our Phoenix engine tuning shop, we have the tools and expertise to help you unleash the true power of your car, truck, or SUV. Our sales staff will help you select the best engine tuner for your application.

Our expert installers will use the handheld tuner to help you dial your motor in and unleash the true performance potential of your car, truck, or SUV.

Cold Air Intakes

Looking to improve the airflow into your motor for increased horsepower, torque, and responsiveness? A Cold Air Intake is one of the first steps many automotive enthusiasts take when they’re looking for a performance boost for their ride. Cold Air Intakes help improve the air flow into your engine allowing it to breathe easier and get a better combustion out of your motor. Better combustion, cooler air, and more air flow are the perfect recipe for more horsepower and torque as well as improved gas mileage.

Cold Air Intakes come in a variety of size, shapes, and styles from a number of aftermarket parts manufacturers. At our Phoenix Cold Air Intake shop, we have the expertise, knowledge, and tools to help you select the perfect Cold Air Intake for your vehicle and install it with expert precision.

Performance Exhaust

At our Phoenix performance exhaust shop, we have the tools, equipment, expertise, and knowledge to install any performance exhaust system you’re looking to add to your vehicle. A performance exhaust upgrade is typically step two in most performance upgrade packages. An aftermarket performance exhaust will not only allow improved exhaust flow and less restriction in the combustion chamber leading to improved performance, the changes in the muffler design will give your ride that aggressive performance sound you want out of a performance car, truck, or SUV.
