Engine longevity starts with clean air intake. The KLX-1262 + KLX-1263 Primary Air Filter set is a critical first line of defense. This essential component is a key part of genuine Sinotruk howo parts for engine maintenance. It traps harmful dust and debris before they enter the combustion chamber. The KLX-1262 and KLX-1263 filters work together to ensure optimal airflow and purity. They protect vital engine components from abrasive wear.
Air Filter (Primary)
Воздушный фильтр (первичный)
Filtro de Aire (Primario)
The primary air filter is the engine’s first guardian. The KLX-1262 + KLX-1263 set captures contaminants from incoming air. Diesel engines require massive volumes of air for combustion. This air contains dust, pollen, soot, and other particles.
Without filtration, these abrasive particles enter the engine. They cause rapid wear to cylinders, pistons, rings, and turbocharger blades. The genuine KLX-1262 and KLX-1263 filters use advanced media. They provide high filtration efficiency with minimal airflow restriction.
This balance is critical for engine performance and fuel economy. A clogged filter restricts air, causing power loss and black smoke. A poor-quality filter allows dirt to pass, causing internal damage. The correct set is essential.
Maximum Engine Component Protection
High-efficiency media traps over 99.9% of harmful particulate matter, dramatically extending the life of cylinders, turbochargers, and valves.
Optimized Fuel Efficiency & Power Output
Precise pleat design maintains optimal air-to-fuel ratio, ensuring complete combustion for maximum horsepower and lower fuel consumption.
Reduced Exhaust Emissions
Clean air intake promotes efficient combustion, minimizing unburned hydrocarbons and particulate matter in exhaust gases.
Long Service Life & Durability
Constructed with robust housing and moisture-resistant media, capable of withstanding high under-hood temperatures and vibration.

The air intake system is designed for multi-stage filtration. The KLX-1262 + KLX-1263 set serves as the primary stage. Air enters the intake stack, often with a pre-cleaner. It then flows into the primary filter housing.
The filter media is a pleated, porous paper or synthetic material. As air passes through, particles are trapped on the surface. The clean air continues to the turbocharger and intake manifold.
The large surface area of the pleats allows high airflow. It also provides a substantial dirt-holding capacity. This design delays the need for replacement under normal conditions.
Some systems use a restriction indicator. It signals when the KLX-1262 + KLX-1263 filter needs changing. Never ignore this warning, as a clogged filter harms the engine.
A dirty primary filter restricts airflow to the engine. The most common symptom is a noticeable loss of power. The truck may feel sluggish, especially when climbing hills.
Increased black smoke from the exhaust is another key sign. This indicates a rich fuel mixture due to insufficient air. Fuel economy will also deteriorate significantly.
The engine may stall or hesitate under heavy load. Unusual sounds from the intake, like whistling, can occur. Visually, a severely clogged filter will appear dark and packed with dirt.
Operating with a restricted KLX-1262 + KLX-1263 filter is wasteful. It increases fuel costs and strains the engine. Regular inspection and replacement are cost-effective practices.
Replacement intervals vary based on operating environment. Normal highway service allows longer intervals. Off-road or dusty conditions demand much more frequent changes.
Always follow the manufacturer’s recommended service schedule. Visually inspect the KLX-1262 + KLX-1263 filters during routine maintenance. Hold a light behind the filter media.
If no light is visible through the pleats, replacement is due. Never tap or blow compressed air on a disposable filter. This can damage the media and allow dirt to pass through.
Always replace both filters in the set together. Using one old and one new filter disrupts airflow balance. Keep a maintenance log to track service history accurately.
The service life of the KLX-1262 + KLX-1263 set is environment-dependent. Driving on paved highways in clean air maximizes life. Construction sites, mines, and desert roads are extreme.
In dusty conditions, the filter can clog in a matter of days. Agricultural operations with chaff and pollen are also challenging. Wet and humid environments can cause media to degrade.
Fleet managers must adjust schedules accordingly. Using a pre-cleaner or cyclonic separator can help. It removes larger debris before reaching the primary filter.
This extends the service interval for the KLX-1262 + KLX-1263. It is a worthwhile investment for severe-duty operations. Protecting the engine is always the top priority.
The genuine KLX-1262 + KLX-1263 filters use engineered media. It is not ordinary paper. The material is resin-impregnated for strength and moisture resistance.
The pleating process creates consistent channels for air. It maximizes surface area within a compact housing. The media is designed to trap microscopic particles effectively.
Gaskets and seals are made from flexible, durable materials. They ensure an airtight fit in the filter housing. This prevents unfiltered air from bypassing the media.
Counterfeit filters often use inferior media and poor seals. They may look similar but fail prematurely. Always insist on the genuine KLX-1262 + KLX-1263 set for guaranteed protection.
An air filter is one of the most cost-effective maintenance items. The price of the KLX-1262 + KLX-1263 set is relatively low. Compare this to the cost of a major engine overhaul.
Replacing worn cylinders, pistons, and a turbocharger is extremely expensive. It also results in significant vehicle downtime and lost revenue. A failed filter can cause all this damage.
Regular filter changes are a form of insurance. They preserve the engine’s internal tolerances and efficiency. This maintains power output and fuel economy over hundreds of thousands of miles.
For fleet operators, this calculation is clear. Never extend filter life to save a small amount of money. The genuine KLX-1262 + KLX-1263 is an investment in the entire asset.
The Primary Air Filter set, part numbers KLX-1262 + KLX-1263, is fundamental to engine health and operational economy. It is a small component with an enormous responsibility: safeguarding the heart of your SINOTRUK Howo.
Choosing the genuine KLX-1262 + KLX-1263 filter set ensures optimal filtration performance, engine longevity, and lower total operating costs. Protect your investment by trusting only authentic OEM air intake components for every service interval.
