How to increase the horsepower in a Ford S-Max?

I have a Ford S-Max and I want to increase its horsepower. What are some recommended modifications or upgrades that I can do? Will it affect the car's performance or fuel efficiency?

Adding a cold air intake and upgrading the exhaust system can help increase horsepower in your Ford S-Max. However, keep in mind that these modifications may also impact your car's fuel efficiency.

Another option would be to install a performance chip or tune your engine for better performance. Just make sure to consult with a professional mechanic before making any changes.

Don't forget to regularly maintain your car, such as changing the air filter and using high-quality fuel and oil. This can also help improve your car's horsepower and overall performance.
