* Reduced fuel economy: You're wasting fuel and money.
* Increased emissions: Harmful pollutants are released into the atmosphere.
* Engine damage: Incomplete combustion can cause damage to various engine components over time.
* Legal issues: In many places, excessively smoky exhaust is illegal and can result in fines.
While some modifications might *seem* to increase smoke output (like increasing fuel delivery), they achieve this at the cost of the points listed above. Instead of trying to make black smoke, focus on proper maintenance and tuning for optimal performance and efficiency. If you're experiencing black smoke already, it's a sign of a potential problem that needs professional diagnosis and repair.
