The Pontiac G8 is a powerful vehicle that offers an exhilarating driving experience. However, many enthusiasts look for ways to enhance its performance further. One of the most effective methods to achieve this is by installing a performance intake and exhaust system. This DIY guide will walk you through the steps to install these components, helping you save money while boosting your car’s power.
Why Upgrade Your Pontiac G8’s Intake and Exhaust?
Upgrading your Pontiac G8’s intake and exhaust systems can significantly improve its performance. Here are some reasons why:
