Engine Box (pre 4.2.0)

The Engine Box is a Pro Kit Box in Asphalt 8: Airborne that appears as Engine Box 1 to Engine Box 5. As all Engine Boxes have the same drop rates, it is probable that they don't differ except for the number of cards contained.

Availability
Engine Boxes can be obtained from time-limited events (TLEs). Since the Fast Lane Update, Engine Box 3 and 5 can also be obtained from Mastery.

Engines
Engine Boxes are a good choice for all of the most needed engines, especially for V12 Engines.
