The most visible change was the required one to the engine's air intake location, as the Jumo 213's supercharger intake was located on the starboard side of the engine (as standard for all models of the earlier Junkers Jumo 211 inverted V12), versus the DB 603's portside location, the standard for all Daimler-Benz inverted V12 engine designs.
O cambio máis notable foi a reubicación da toma de aire, xa que a toma do sobrealimentador do Jumo 213 estaba localizada no costado de estribor do motor (como estándar para todos os modelos do anterior Junkers Jumo 211 en V12 invertida), mentres que o DB 603 o tiña localizado a babor, o estándar para todos os deseños de motor V12 invertida de Daimler-Benz.
