Product Description

.update:2025-07-02.
The truck air filter is generally large in size and expensive, so choosing a good air filter is very important for the truck engine. It can be easily identified from the following points. First, look at the filtration efficiency of the filter paper. This is very important because a filter with high filtration efficiency can effectively prevent dust from entering the engine, providing excellent protection. Our air filter is made of Ahlstrom filter paper, with a filtration efficiency of 99.9%. Then we need to see what grade of sealant is used. Natural rubber is soft, elastic, and resistant to aging. Our product is made of high-quality natural rubber, which is very up to standard. Finally, look at the frame. A good frame supports the air filter and is not easily deformed, especially in high-pressure environments, which can maintain the engine's intake air volume well without affecting power output.
