Core Selling Points
Hot aftermarket ma

intenance spare part with steady repeat orders
It is a frequently replaced component for imported Audi Q7 engine overhaul. Long-term high-temperature engine operation easily leads to housing cracking, seal aging and oil leakage of original units. Repair garages and auto parts wholesalers keep placing continuous bulk orders, bringing stable sales volume and profit margins for distributors.
OE-standard full precise dimensional matching
Manufactured strictly following OEM mold and technical specifications. Mounting hole layout, oil inlet/outlet passage size, filter thread specification and sealing surface outline are fully consistent with genuine parts. Direct bolt-on installation without cutting, grinding or pipeline modification, greatly saving repair labor time.
Reinforced high-temperature resistant housing structure
Adopts thickened high-strength reinforced plastic with anti-deformation treatment. Built-in high-temperature oil-resistant rubber sealing gaskets with anti-aging formula. It resists long-term erosion of high-temperature engine oil, effectively preventing gasket hardening, cracking and engine oil seepage.
Smooth oil circulation protects engine lubrication system
Optimized internal oil channel design ensures unobstructed engine oil circulation and stable oil pressure. It avoids insufficient lubrication caused by blocked or leaking housing, reducing wear of crankshaft, camshaft and other moving parts, and extending engine service life.
