Bangkok: Fact-checking efforts have confirmed that the smell of gasoline entering the passenger compartment is a valid concern. Reasons for this include leaky fuel lines, worn fuel pump O-rings, and leaky fuel tanks.

According to Thai News Agency, the "Sure Before Sharing" center verified this information with Assoc. Prof. Dr. Jinda Charoenpornpanich, Chair of the Advanced Automotive and Transportation Engineering Program at King Mongkut's Institute of Technology Ladkrabang. The center's findings conclude that the claim is true and can be shared.

In a related automotive discussion, the advantages and disadvantages of open air filters have been highlighted. Open air filters, unlike factory-installed options, allow greater airflow and are beneficial in older car models, especially those from the 1990s. These filters can improve engine airflow and efficiency significantly. However, their installation requires a well-designed mounting kit to direct cool airflow and prevent engine heat intake.

Despite their benefits, open air filters present several drawbacks. Their reduced dust filtration efficiency allows larger particles to enter the engine. They also draw in hot air during congested traffic conditions, leading to increased engine heat and reduced efficiency. Moreover, they pose a high risk of water entering the engine, which can cause severe damage.

Experts caution that modern cars come with highly efficient intake manifolds and air filters. An aftermarket air filter may not enhance performance in standard vehicles and could reduce overall efficiency by increasing intake noise. For those interested in upgrading their air filtration systems, experts recommend using washable element aftermarket filters, which provide similar airflow benefits but are safer and more suitable.

In summary, while installing an open air filter can improve performance in older vehicles, it is not recommended for newer models due to potential disadvantages and costs.
