What is the best engine upgrade for a Nissan 370Z?

I want to increase the power of my Nissan 370Z but I am not sure which engine upgrade is the most reliable and effective. Any suggestions?

A cold air intake and exhaust system are a great starting point for increasing power in a Nissan 370Z. Look for reputable brands like Injen and Borla.

If you're looking for significant power gains, a supercharger or turbocharger kit would be your best bet. But be prepared to spend a considerable amount of money and invest in supporting modifications.

Don't forget about tuning and engine management. Upgrading to a standalone engine management system can help optimize your performance upgrades and ensure everything is working together efficiently.
