Vauxhall Opel Astra K Diesel Fuel Filter Element Kit with Gasket for MK VII Models

This replacement diesel fuel filter element and gasket kit is engineered to the precise specifications required for Vauxhall Astra MK VII (K) and Opel Astra K models, including the Sports Tourer estate variant. It serves as a direct, genuine-quality replacement part, identified by multiple compatible OEM part numbers such as 23304095 and 23304096. Designed for vehicles manufactured from mid to late 2015 onwards, this filter is a critical maintenance component. Its role is to protect the engine's fuel injectors and fuel pump by filtering out particulate contaminants present in diesel fuel, thereby supporting consistent engine performance and helping to prevent potential fuel system issues. The inclusion of a new sealing gasket ensures the replacement service is complete, preventing leaks and maintaining system pressure.

Features and Construction

This filter kit is defined by its exact fitment and comprehensive service design, providing everything needed for a standard fuel filter replacement on specified Astra K models.

Material and Build

The core of the product is the fuel filter element itself, constructed from specialised filtration media capable of capturing fine impurities from diesel fuel. This media is housed within a casing designed to withstand fuel pressure and chemical exposure. The accompanying gasket is made from a compatible sealing material, formulated to remain pliable and create a durable, leak-proof seal between the filter housing and its cap or base, which is essential for maintaining correct fuel system pressure.

Size and Practical Fit

Accurate dimensions are paramount for automotive filters. This element measures 106mm in height, allowing it to sit correctly within the designated filter canister. Its outer diameter is specified as 88mm to 90mm, ensuring it fits snugly inside the housing without unwanted movement. The maximum inner diameter of 24.5mm accommodates the central mounting post or fuel line connection within the assembly. These measurements are not approximate; they are production specifications that guarantee compatibility and correct installation for the targeted vehicle applications.

Uses and Placement

This product has a single, clear purpose: to replace the worn or contaminated diesel fuel filter in specific Vauxhall and Opel vehicles as part of scheduled maintenance.

Event or Professional Use

For professional mechanics or workshops servicing the Vauxhall and Opel range, this filter is a standard service item for the Astra K platform. It is used during routine service intervals, major services, or when diagnosing fuel-related performance issues. Having the correct part number and dimensions ensures workshop efficiency and eliminates fitment problems, making it a reliable stock item for garages specialising in these marques.

Everyday Home Use

For the knowledgeable vehicle owner who performs their own maintenance, this filter kit provides a straightforward replacement option. Its compatibility is clearly listed for Astra MK VII (K) hatchbacks and estates from November 2015, and Opel Astra K models from June 2015. By matching the part numbers (23304095, 23304096, etc.) to their vehicle's existing filter or service manual, a home mechanic can confidently source the correct part for a DIY service, saving on garage labour costs for this standard procedure.

Benefits and Buying Value

The value of this filter lies in its specification-matched design, which supports vehicle reliability and straightforward servicing.

Reuse and Low Maintenance

As a consumable service item, this filter is not designed for reuse but for periodic replacement. Its value is realised through the reliable service interval it provides. Using a correctly specified filter helps maintain optimal fuel flow and filtration, which can contribute to the long-term health of expensive fuel system components like injectors and high-pressure pumps, potentially avoiding more costly repairs down the line.

Why Choose This Product

This product is chosen for its verified compatibility with a popular vehicle platform. It addresses the specific need for a fuel filter that matches the factory dimensions and comes with the necessary gasket. The alternative is risking the use of an incorrectly sized or poorly sealing filter, which could lead to fuel leaks, pressure loss, or even engine damage. This kit removes that guesswork by providing the exact components listed for the service, making it a practical and risk-averse choice for maintaining your Astra K's fuel system.
