2018 Hyundai Ioniq Plug-In Hybrid Oil Filter in Peoria, AZ

Yes—the oil filter is replaced with the oil change so debris doesn’t recirculate through the engine.

As a filter loads, its bypass valve opens to maintain flow; oil still circulates, but it circulates unfiltered. Replacing the filter at each oil change restores full filtration and helps protect bearings, timing components, and variable controls. Follow the manufacturer’s schedule and your driving conditions.

• Fresh filter prevents debris from returning to critical surfaces.
• Bypass events decrease when a new filter is installed.
• Aligned with the service interval for your usage pattern.

The service includes draining oil, installing a filter matched to this engine, renewing sealing surfaces, refilling with the specified oil, and checking for leaks.

Technicians verify the old gasket is removed, clean the mounting pad, fit the new filter, and warm the engine to confirm proper sealing and stable oil pressure. The oil level is set and the reminder is reset where applicable. Book online to keep your hybrid running clean.

• Filter matched to the 1.6L inline-4’s requirements.
• Gasket/o-ring replaced and sealing surfaces cleaned.
• Post-service inspection and leak check after warm-up.

The filter can load up, the bypass valve can open, and unfiltered oil can circulate—quietly increasing wear.

While oil flow continues, suspended particles bypass the media and return to bearings and cam journals. Over time, that can accelerate abrasion and sludge formation. Replacing the filter at each oil change restores filtration and supports engine longevity.

• Higher particle load in circulating oil.
• Increased wear on precision surfaces.
• Potential for deposits in tight oil passages.

Yes—the filter is matched to the 1.6-liter, 4-cylinder engine, and filters are not interchangeable across engines.

Correct fit ensures proper sealing, media capacity, and bypass pressure suited to this hybrid’s lubrication system. Using a random filter risks poor sealing or incorrect bypass behavior. Your technician will select a filter engineered for this displacement and cylinder count.

• Engine: 1.6L inline 4 on the 2018 model.
• Correct bypass calibration maintains protection.
• Right gasket profile prevents leaks and air ingress.

It can be done, but it is not recommended because a loaded filter can trigger bypass and circulate unfiltered oil.

Changing oil alone leaves the old debris load trapped in the media and risks immediate bypass under hot idle or high load. Replacing both together restores filtration and extends component life. Follow the manufacturer’s schedule for your usage.

• Paired service restores clean oil and filtration.
• Reduces bypass events after the change.
• Protects bearings, camshafts, and VVT hardware.
