Core Selling Points
Hot-selling aftermarket engine maintenance part
It is a high-frequency replacement component for A3/S3 engine overhaul. Original factory assemblies easily suffer gasket aging, housing seepage and unstable oil pressure after long-term high-temperature operation. Repair shops and cross-border auto parts wholesalers place continuous repeat bulk orders, bringing stable sales volume and profit margins for distributors.
OE-standard precise dimensional matching
Manufactured strictly following OEM mold and technical specifications. Mounting hole layout, internal oil channel size, filter thread specification, sensor connector and sealing surface outline are fully consistent with genuine parts. Direct bolt-on installation without cutting, grinding or pipeline modification, greatly shortening maintenance working hours.
Reinforced high-temperature resistant plastic construction
Adopts thickened reinforced modified engineering plastic with anti-deformation treatment. It can withstand long-term erosion of high-temperature engine oil and engine cabin heat, effectively preventing housing cracking and thermal deformation. Supporting high-temperature fluorine rubber sealing gaskets avoid oil leakage caused by aging and hardening.
Optimized internal flow channel for stable lubrication circulation
Smooth integrated oil passage design guarantees unobstructed oil circulation and constant oil pressure under heavy-load and high-speed driving. It effectively reduces abrasion of crankshaft, bearings and valve train components, offering reliable lubrication protection for the whole engine.
Thoroughly fix typical oil filter housing malfunctions
Perfectly solves common faults including oil leakage at housing joints, engine oil loss, fluctuating oil pressure, abnormal engine mechanical noise and oil contamination risks, keeping the engine lubrication system running normally.
Strict multi-process quality testing & ample spot stock
Each oil filter housing assembly passes air tightness leakage test, high-temperature cycle aging test and full dimensional inspection before shipment to ensure long-term reliable service life. Mass ready stock supports fast bulk delivery. Custom neutral packaging and private label services are available to meet cross-border wholesale demands.
