Side filler oil cap kit
A lockable oil filler cap with beautiful engraved OIL inscription for side filler modification

Fits:
Porsche 911 1973 - 1989

This OE Match side filler oil cap kit is a replacement oil filler cap kit for Porsche 911 models from 1973 to 1989. It is designed for the side oil filler system and helps restore correct sealing, appearance, and function of the external oil filler arrangement.

The side filler oil cap closes and seals the oil filler opening, helping prevent oil vapour, oil mist, dirt, and moisture from entering or escaping the oil tank / filler system. A correctly sealing oil cap is important for maintaining the integrity of the dry-sump oil system used on classic Porsche 911 models.

Functions
•  Replaces the side oil filler cap assembly
•  Seals the oil filler opening securely
•  Helps prevent oil vapour and oil mist escape
•  Helps protect the oil system from dirt and moisture entry
•  Restores the correct OE-style oil filler appearance
•  Supports proper dry-sump oil tank sealing
•  OE Match replacement for service, repair, or restoration.

Why Replace This Kit?
Oil filler caps can become worn, loose, corroded, damaged, or lose sealing performance over time. A poor seal may allow oil mist, vapour, dirt, or moisture to pass through the filler area, and can leave the vehicle looking incomplete or incorrect during restoration. Replacing the side filler oil cap kit helps restore secure sealing and the correct classic Porsche finish.

When to Replace This Kit
•   The original side filler oil cap is missing or damaged
•   The cap does not seal securely
•   Oil vapour, oil mist, or residue is visible around the filler area
•   The cap is corroded, loose, cracked, or heavily worn
•   The oil filler neck or surrounding oil tank components are being serviced
•   The vehicle is undergoing Porsche 911 oil system restoration
•   The car is being restored to an OE-style appearance.

Where it fits on the car
This kit fits at the side oil filler opening on Porsche 911 models equipped with the relevant oil filler arrangement. It forms part of the oil tank / filler neck system and should be installed according to the factory oil system layout.
