MAHLE OC21 Spin-On Engine Oil Filter OE Quality Canister

The MAHLE OC21 is a premium spin-on engine oil filter engineered to OE (original equipment) quality standards. Designed for a precise fit and optimal flow rate, this canister-style filter effectively removes harmful contaminants — including combustion residues, dust, oil carbon, soot, abrasion particles, and condensates — from the engine oil before they can cause premature wear to critical engine components.

Key Features:

• OE-Quality Construction: Built to vehicle manufacturers' specifications and high safety standards using quality sheet metal, endplates, and precision seaming
• High-Performance Filter Media: Utilizes high-quality cellulose fibers impregnated with special resins, delivering excellent filtration efficiency and high dust-holding capacity
• Spin-On Canister Style: Easy to service with an outer diameter of approximately 3.07 in. (78 mm), height of approximately 3.07 in. (78 mm), and 3/4"-16UNF-2B connecting thread
• Anti-Drainback Valve: Prevents oil from draining out of the filter when the engine is off, ensuring immediate lubrication on startup
• Bypass Relief Valve: Guarantees continuous lubrication at all times, even under high-load or cold-start conditions where oil viscosity may restrict flow
• Stable Pleat Geometry: Maintains cold-start stability and resists peak pressure loads of up to 20 bar
• Protects Engine Components: Guards valves, cylinder surfaces, piston rings, bearings, and other critical components against premature wear

MAHLE is a world-leading manufacturer supplying OE and aftermarket filtration solutions to major automotive manufacturers globally. The OC21 oil filter is sold individually and should be replaced at the intervals prescribed by the vehicle manufacturer to maintain engine health and longevity.
