What is the Engine Air Filter-PU & Why It Matters
Every combustion engine needs clean air to mix with fuel. Dust, debris and other particles in intake air can damage engine internals, reduce efficiency, lower performance, increase emissions, and shorten engine life.
An Engine Air Filter (PU-Premium) is placed in the air intake path (usually in the air box) to:
block harmful particles (dust, sand, pollen etc.)
allow sufficient airflow for engine performance
resist heat, pressure, and environmental stress
maintain durability over long driving hours or distances
The “PU Premium” version is specially designed using higher grade materials (Polyurethane in some cases, strong PU frames) and advanced media to give superior performance compared to standard filters.

Why Choose Engine Air Filter Bangladesh – Premium vs Cheaper Alternatives
As a car owner in Bangladesh, you face unique challenges:
heavy dust and particulates (especially in Dhaka, Gazipur, etc.)
heat, humidity, occasional flooding / heavy rains
variable road quality
A premium air filter such as ours gives:
Better protection under dust load: holds more dust without clogging quickly.
Consistent engine performance: avoids throttle lag, black smoke, loss of power.
Cost savings over time: fewer replacements, fewer issues requiring mechanic intervention.
Installation & Maintenance Tips
Replace the filter at the recommended interval (≈ every 5,000-6,000 km under Bangladesh’s conditions, or sooner if in heavy dust).
Always inspect the air box seal and filter frame for leaks.
Clean the air box housing to prevent degraded seal & dirty air bypass.
Check after monsoon or flooding; moisture can degrade filter paper/media.

FAQ (Frequently Asked Questions)
Q1: How often should I replace the Engine Air Filter-PU-Premium in Bangladesh?
A1: Generally, under moderate traffic & dust, every 5,000-6,000 km. If you often drive in heavy dust or on unpaved roads, check earlier (every 3,000-4,000 km).
Q2: Will a premium air filter improve fuel efficiency?
A2: Indirectly yes — because better air flow and proper fuel-air ratio lead to more efficient combustion, which can improve fuel economy, reduce black smoke and reduce engine stress.
Q3: Is the OEM-17801-31170 the same as 17801-31100 or 17801-31179?
A3: They are very similar / cross-referenced OEM numbers. If shape, seal, dimensions match on your vehicle model, they are interchangeable. Always verify fit before installation.
Q4: Can I wash and reuse this PU-Premium filter?
A4: No — PU-Premium paper/fabric filters are generally disposable. Washing will damage the filter media, change pore size, reduce filter life and performance.
Q5: Does this filter fit my Lexus / Toyota model?
A5: It fits models which require OEM code 17801-31170 (and equivalents 17801-31100 / 17801-31179). Check your car’s manual or existing filter to confirm. If unsure, contact our hotline or email, we can help confirm compatibility.
