Cold Air Intakes
Many E46 330i owners report that installing a cold air intake system improves throttle response and adds a noticeable increase in horsepower. The enhanced airflow allows the engine to breathe better, which can lead to improved performance.
Owner Feedback
Owners have shared mixed experiences regarding reliability post-installation. Some have noted that the increased airflow can lead to slightly higher engine temperatures, which may affect longevity if not monitored closely.
Performance Exhaust Systems
Upgrading to a performance exhaust system is another popular modification. This upgrade not only enhances the sound of the vehicle but can also improve exhaust flow, leading to a potential increase in horsepower.
Owner Feedback
Many owners report a more aggressive sound and a slight performance boost. However, some have experienced issues with drone at highway speeds, which can detract from daily driving comfort.
