What are the best upgrades for my Ford Transit Custom engine?

I recently purchased a Ford Transit Custom and I'm looking to upgrade the engine for better performance. What are some recommended upgrades and how do they affect the engine's overall performance?

I would suggest installing a cold air intake and a performance exhaust system. These upgrades can increase horsepower and torque, giving your Transit Custom a noticeable boost in power and speed.

Another great upgrade is a performance chip or tuner. These devices can optimize your engine's fuel and ignition parameters for increased power and efficiency. Just make sure to do your research and choose a reputable brand.

If you're willing to invest more, a turbocharger or supercharger can provide even more power. However, these upgrades can be costly and may require additional modifications to your engine.
