LF3345 Engine Oil Filter

JZHILAN LF3345 is a specialized engine oil filter exclusively developed for vehicles complying with China’s National V/VI emission standards, and it is tailored for high-pressure common rail systems— a key component in modern diesel engines. Manufactured by Shanghai Jingzhi Blue Filter Co., Ltd. (branded as JZHILAN), this filter positions itself as an "expert in medium filtration and separation technology," aiming to safeguard engine performance and longevity.

Its core function is to capture and remove harmful impurities, metal particles, sludge, and contaminants from engine oil during circulation. By maintaining clean oil, it reduces friction and wear on critical engine parts (including cylinders, pistons, crankshafts, and bearings), which is especially crucial for high-pressure common rail systems that demand precise, low-contamination operating environments.

Constructed with high-quality filter media and durable materials, the LF3345 ensures consistent filtration efficiency even under heavy-duty working conditions (such as in commercial trucks, construction machinery, or long-haul vehicles). It is recommended to pair this filter with fully synthetic engine oil that meets the vehicle’s specifications; when the filter reaches its service limit (often indicated by engine system alerts or scheduled maintenance intervals), prompt replacement is necessary to avoid reduced oil flow or compromised engine protection.

As a targeted solution for National V/VI vehicles, this filter aligns with stricter emission and performance requirements, helping engines maintain optimal efficiency, lower maintenance costs, and extended service life over time.
