Auto LPG systems are installed in many vehicles on our roads today to reduce fuel costs and improve air quality. These vehicles require significantly more extensive and important auto maintenance than gasoline or diesel-powered ones. While various factors heavily influence the effectiveness of LPG, it is essential to regularly have your automobile serviced and maintain a properly functioning ignition system. Backfires caused by a malfunctioning ignition system can create intake area explosions, which can damage or destroy components, including air cleaner housings, intake pipes, and intake manifolds, especially on newer models of cars with plastic manifolds. Most LPG systems call for regular returns to compensate for the lower airflow into the engine when air filters get dirty from doing their job as intended.
