Ryco Z411 Spin-on Oil Filter

OEM-equivalent oil filtration that protects your engine and maintains new vehicle warranty—proven Ryco quality.

Product Overview

The Ryco Z411 spin-on oil filter delivers OEM-specification engine protection for a wide range of Australian and imported vehicles, combining 35-micron particle filtration with anti-clogging internal construction that maintains clean oil flow throughout the service interval. This M20x1.5 threaded filter fits directly to the engine block using the standard spin-on design found across countless passenger cars, light commercials, and SUVs, providing straightforward replacement during routine servicing. Ryco's internal filtration media captures damaging contaminants—metal particles from engine wear, carbon deposits from combustion blow-by, and abrasive dirt that enters through the air intake—while the 1-bar bypass valve ensures continuous oil flow to critical engine components even if the filter media becomes restricted in extreme cold starts or extended service intervals. At 86mm height and 69.5mm diameter, the Z411 fits within standard engine bay clearances, and the factory-spec 64mm seal diameter ensures leak-free mounting to OEM and aftermarket oil filter housings. Ryco backs this filter with warranty protection that maintains new vehicle warranty coverage when used according to manufacturer service schedules, making it the smart choice for DIY servicing and professional workshops maintaining customer vehicles.

Features & Benefits

35-Micron Filtration Captures Damaging Contaminants
The 35-micron filtration rating means this filter traps particles larger than 35 micrometres (0.035mm)—the threshold where abrasive particles begin causing measurable cylinder bore wear, bearing surface damage, and accelerated component degradation. This captures metal shavings from cam and crank wear, carbon deposits from piston blow-by, and silica dust that enters through the air intake, while allowing beneficial oil additives (typically under 10 microns) to circulate freely.

Anti-Clogging Media Maintains Oil Flow Across Service Intervals
Ryco's filtration media uses pleated construction with synthetic reinforcement that resists clogging and maintains structural integrity even when saturated with contaminants near the end of the service interval. Unlike cheap filters where media can collapse or bypass prematurely, the Z411's engineered filter media maintains particle capture efficiency while providing consistent oil flow—critical for maintaining oil pressure at idle and under high-load conditions.

1-Bar Bypass Valve Protects Engine During Cold Starts
The integrated bypass valve opens at 1 bar (14.5 PSI) differential pressure, allowing oil to bypass the filter media if restriction becomes excessive—typically during cold starts when thick oil struggles to flow through filter media, or if the filter becomes heavily contaminated beyond its service life. This bypass function prevents oil starvation to bearings and cam lobes, choosing unfiltered oil flow over no oil flow. Once oil warms and flows normally, the bypass valve closes and filtration resumes.

M20x1.5 Thread Fits Common Australian Vehicle Applications
The M20 x 1.5 metric thread is one of the most common oil filter thread sizes found in Japanese vehicles (Toyota, Nissan, Honda, Mazda, Subaru, Mitsubishi), Korean vehicles (Hyundai, Kia), and many European applications. This standardised thread size allows direct spin-on installation to the engine block or oil cooler housing without adapters or modification.

OEM-Equivalent Construction Maintains New Vehicle Warranty
Ryco filters meet or exceed original equipment manufacturer specifications for filtration efficiency, bypass valve operation, media capacity, and seal integrity. Using Ryco filters during warranty-period servicing maintains your new vehicle warranty protection under Australian Consumer Law, provided you follow manufacturer-specified service intervals and use appropriate oil grade. This protects against dealer warranty claims that aftermarket filters void coverage.

64mm Seal Diameter Ensures Leak-Free Mounting
The 64mm seal outside diameter matches OEM filter base dimensions, ensuring the rubber O-ring seal mates correctly with the engine's oil filter mounting surface. Proper seal diameter prevents both over-compression (which can damage the seal and cause leaks after thermal cycling) and under-compression (which allows oil seepage around the seal).

Compact 86mm Height Fits Tight Engine Bays
At 86mm overall height, the Z411 maintains clearance in modern compact engine bays where oil filter access may be tight against subframes, steering racks, or exhaust components. This height specification matches the OEM filter envelope, preventing interference with surrounding components during installation and normal operation.

Ryco Quality with Australian Market Focus
Ryco is Australia's leading independent filter manufacturer with decades of experience engineering filters for local conditions—high ambient temperatures, dusty environments, extended oil change intervals, and the specific vehicle mix sold in the Australian market. Local engineering and testing ensures fitment accuracy and performance validation for vehicles operating in Australian conditions.

Frequently Asked Questions

What vehicles does the Ryco Z411 fit?
The Z411 fits numerous vehicles using M20x1.5 thread oil filter mounts. 

Can I use this filter with synthetic oil?
Yes, the Z411 is fully compatible with synthetic, semi-synthetic, and mineral-based engine oils.

How tight should I install the spin-on filter?
After lubricating the O-ring seal with clean engine oil, spin the filter on by hand until the seal contacts the mounting surface, then tighten an additional 3/4 to 1 full turn by hand only. 

Does this filter include an anti-drainback valve?
Most Ryco spin-on filters, including typical Z-series filters, incorporate an anti-drainback valve (a rubber flap valve inside the filter) that prevents oil from draining out of the filter when the engine is off.

How do I know when to replace the oil filter?
Replace the oil filter at every oil change, following your vehicle manufacturer's recommended service interval.
