The Air Filter is the first "protective barrier" of a car engine. It is responsible for filtering impurities such as dust, pollen and sand particles in the air to ensure that the air entering the engine is clean and stable.
The correct selection of air filters can not only enhance vehicle performance but also significantly extend the engine's lifespan.
Precisely match according to the vehicle model
The first criterion for choosing an air filter element is the model of the vehicle.
The filter element size, shape and interface structure of each model are different. If there is a dimensional deviation or the seal is not tight, it will lead to:
Unfiltered air bypasses into the engine
Abnormal intake volume
The engine operates unstably or even gets damaged
Suggestion
Subject to the original factory Number (OE Number)
Or precisely match by vehicle model + year
For example: 17801-21060 (commonly used models of Toyota)
Look at the material of the filter paper: the core of filtration efficiency
The filtration effect of the air filter element is mainly determined by the filter paper.
Wood pulp filter paper (conventional
High cost performance
The filtration effect is stable.
Suitable for most vehicle usage environments
Synthetic fiber Filter Paper (High Efficiency)
High filtration efficiency
It has better moisture resistance
Have a longer lifespan
Nanofiber filter Paper (High-End)
It can filter out smaller particles
More durable and efficient filtration
It is used in high-demand or high-dust environments
Selection suggestion
Ordinary family cars → wood pulp or synthetic fibers
High dust, off-road, taxi → high-efficiency or nanofiber filter paper
Check the balance between the filtration efficiency and the resistance
The quality of an air filter should not only be judged by its filtration efficiency, but also by the balance of "efficiency + resistance".
High filtration efficiency
✔ Block more dust
✔ Better protection for the engine
Low resistance
✔ Large air flow
The engine runs more smoothly
✔ Lower fuel consumption
An excellent air filter element should meet:
Dual standards of high filtration and no impact on air intake.
Check the origami structure: It is related to the lifespan and performance
The air filter element increases the filtration area through origami. The more scientific the origami, the better the effect.
Key points for selection:
The origami is neat.
Uniform spacing
The height of the fold is reasonable
There is no deformation or collapse
Excellent origami can ensure:
The filtration area is larger
Have a longer lifespan
It is not easily flattened and affects the airflow
