This high-sales 22-tooth engine oil pump with standard OE part number 06H115105CT is a premium aftermarket lubrication component specially designed for Volkswagen and Audi EA888 Gen2 and Gen3 1.8T and 2.0T turbocharged engines. It covers a wide range of mainstream models equipped with EA888 powertrains, including Audi A3, A4, A5, Q3, Q5, Volkswagen Passat, Tiguan, Golf GTI, Magotan and Skoda series vehicles. As a core pressure supply unit for the engine lubrication system, this 22-tooth oil pump undertakes the critical task of pressurizing, circulating and delivering engine oil to every moving part of the engine. With precise original gear parameters and stable oil pressure output performance, it has become the best-selling replacement solution for solving common lubrication failures and aging oil pump problems on EA888 series engines, favored by auto repair shops and parts wholesalers worldwide.
The EA888 turbocharged engine features high power density, high operating temperature and strict lubrication requirements, making the oil pump’s flow stability and pressure accuracy decisive factors for engine durability. Professionally customized with exclusive 22-tooth gear structure, the 06H115105CT oil pump completely matches the original transmission ratio and power output logic of EA888 engines. Different from mismatched 24-tooth or inferior universal oil pumps on the market, its precise tooth spacing and gear meshing design ensure stable oil pressure build-up during cold start, idle operation and high-load acceleration. It rapidly delivers engine oil to key components such as crankshaft, camshaft, piston rings, timing chain and turbocharger, forming a complete protective oil film to reduce mechanical friction, lower operating temperature and avoid dry wear caused by delayed oil supply or insufficient pressure.
One of the core advantages of this high-selling EA888 oil pump is its excellent adaptive performance for extreme working conditions. EA888 engines are prone to high-temperature operation during long-distance driving and urban frequent start-stop cycles, which easily leads to attenuation of oil pressure from aging pumps and insufficient lubrication. The 06H115105CT oil pump adopts upgraded high-precision alloy rotor and wear-resistant gear materials, featuring low friction coefficient and strong high-temperature stability. It maintains constant oil flow and rated working pressure even under long-term high-temperature and high-load conditions, effectively preventing power attenuation, abnormal engine noise and turbo lag caused by unstable lubrication. In low-temperature winter environments, the optimized gear clearance design realizes quick oil pressure establishment, minimizing cold-start wear which causes the majority of engine service life loss.
Manufactured in strict accordance with OE original factory standards, the overall dimensions, mounting hole positions, gear parameters and interface specifications of the 06H115105CT 22-tooth oil pump are 100% consistent with original parts. It supports plug-and-play direct installation without any modification, drilling or pipeline adjustment, greatly improving maintenance efficiency and avoiding installation errors caused by mismatched accessories. The pump body adopts high-strength die-cast aluminum alloy material, which integrates excellent pressure resistance, deformation resistance and heat dissipation performance, adapting to the harsh high-temperature environment of the EA888 engine compartment for long-term operation. The optimized internal oil channel structure reduces oil flow resistance, improves lubrication efficiency, and effectively avoids oil pressure loss and pump body vibration during operation.
Every 06H115105CT oil pump undergoes strict multi-process factory testing before delivery, including oil pressure calibration testing, full-load endurance operation testing, high and low temperature cycle aging testing, gear meshing precision inspection and sealing performance testing. Each product is screened layer by layer to ensure stable oil pressure output, uniform flow rate, low noise and no jitter during operation. The precise 22-tooth gear grinding process ensures tight meshing without jamming or abrasion, effectively extending the overall service life of the oil pump. Compared with ordinary low-cost oil pumps that suffer from easy gear wear, slow pressure build-up and unstable operation, this high-quality product maintains long-term consistent lubrication performance and effectively reduces later maintenance frequency.
Aging and failure of the original oil pump are typical high-frequency faults for high-mileage EA888 engine vehicles. Common failure symptoms include persistent low oil pressure warning on the dashboard, abnormal engine knocking noise, sluggish power acceleration, increased fuel consumption, obvious jitter during cold start, and slow oil pressure rise. If the faulty oil pump is not replaced in time, insufficient lubrication will cause severe wear of crankshaft bearings and camshafts, aggravate timing chain stretching, and even lead to turbocharger damage and engine cylinder scuffing in severe cases, resulting in extremely high overhaul costs and seriously affecting driving safety and vehicle stability.
Widely recognized in the global auto parts aftermarket, the 06H115105CT 22-tooth oil pump stands out for its accurate OE matching, stable performance and ultra-high cost performance. It perfectly solves the inherent defects of original aging oil pumps and inferior replacement parts, such as insufficient oil pressure, easy wear and short service life. Suitable for routine vehicle maintenance, fault repair and engine overhaul of all EA888 1.8T/2.0T models, it is the preferred bulk supply and retail replacement part for professional repair workshops and parts dealers. Installing this high-sales standard oil pump can fully restore the original lubrication performance of EA888 engines, stabilize engine operating condition, reduce failure rate, and provide long-term and reliable lubrication protection for Volkswagen and Audi EA888-powered vehicles.
