Additionally, you can upgrade your ignition system for enhanced efficiency. With the right parts and tuning, you can take your Cadillac XT4 to the next level.

Upgrading Ignition Systems for Enhanced Efficiency

Upgrading ignition systems is another great way to improve engine efficiency on your Cadillac XT4. Swapping out stock coils for high-performance ones can provide greater spark intensity which helps burn fuel more efficiently resulting in improved throttle response and increased horsepower. Additionally, adding an aftermarket ignition box can help fine-tune timing settings for maximum power output from each cylinder of the engine making it possible to get even better results from modified components such as turbochargers or cold air intakes.
