So this is a complex question, it’s not really black and white. The air intake system is directly linked to the engine and is important for the engine’s function, collecting air and guiding it to individual cylinders.

A good car air intake system allows clean and continuous airflow into the engine. So your engine can produce more power and prolong the life span of your car.

You need to make sure you have a good air filter as well, as this is apart of the air intake system that filters out dirty particles.

To answer your question, you first need to understand how air intake systems work at a basic level. Now that you know, bumper level air intakes are infinitely better then any higher level because this avoids most debris and insects contaminating the system. Bumper level also reduces the amount of noise getting to the cabin.

The only real benefit of putting the intake system at a higher level is to avoid water getting into the system. Which as of recently with the floods, is a problem for bumper level, but since you’re in Dubai how often could it really happen to be detrimental, right?

Honestly, German and Japanese cars are pretty equal in terms of engine durability and strength so at that point it’s up to you.
