Upgrading the BMW XM Engine

I am considering upgrading the engine of my BMW XM to improve its performance. Can anyone provide any insight on the best way to do this?

It's important to do thorough research and consider all options before proceeding with an engine upgrade. Different upgrades may result in different performance improvements and have varying levels of complexity and cost. I recommend consulting with a trusted mechanic or tuning specialist for personalized advice.

Before making any modifications to your engine, it's important to consider the impact it may have on your car's warranty. It's worth asking your dealership or manufacturer for their stance on engine upgrades and whether they offer any official upgrade packages.
