Filler Neck Parts

OEMatch filler neck parts for Porsche models provide the connection between the engine or oil reservoir and the filler cap, enabling controlled oil refilling while maintaining the lubrication system seal. This collection covers filler necks, caps, seals and connecting pipes suitable for air-cooled and water-cooled Porsche engines, useful for routine maintenance, engine rebuilds and restoration work.

OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original filler neck parts.
OE (Original Equipment) refers to parts matching original specifications for the filler neck parts and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM filler neck parts engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.

These components form the filler neck assembly and are typically made from heat- and oil-resistant materials, with seals and O-rings that maintain pressure integrity and prevent contamination.

• Restores airtight sealing to prevent oil leaks and vapour loss.
• Supports clean, controlled oil refilling and reduces contamination risk.
• Replaces degraded pipes, seals and caps to maintain system pressure and reliability.

• Heat and vibration cause pipes and hoses to become brittle and crack.
• Seals and O-rings deteriorate from oil exposure and age, allowing vapour leaks.
• Residue and sludge build-up can impede sealing and lead to poor fitment.

Replacing worn filler neck components preserves oil system integrity, prevents leaks that can cause contamination or oil loss, and keeps servicing straightforward. Correct seals and properly formed filler pipes help the crankcase breathe as intended and support consistent engine operation across model years.

• Parts selected for compatibility with Porsche mounting points and service procedures.
• Materials chosen to resist oil, heat and corrosion for longer service life.
• Suitable for restoration and routine maintenance, covering both classic and modern applications.
