Top 10 Most Common Replacement Service Parts For a Porsche 928

By Tom on Tuesday, July 30, 2024

The Porsche 928 roared into the automotive world in 1978, bringing a blend of power and luxury. At the time, it was the golden standard for grand touring vehicles.

Motor Sport magazine highlighted its remarkable aerodynamic leaps and sophisticated engineering, noting its “pulling power of an ocean-going tug,” and its immediate and predictable response that delivered power smoothly and effectively.

CAR Magazine compared it to the Corvette ZR-1 that came out in 1989, pointing out the Porsche’s superior build and integrated feel. Even though it was a large car, it maintained a sense of intimacy and functionality in the interior. 

Porsche envisioned the 928 as a replacement for the iconic 911. It departed from the company’s grand tradition of rear engine placement, featuring a front, water-cooled V8 engine. For the loving owner of this masterpiece, maintenance and aesthetics are paramount. 

In this guide, we go over the ten most commonly replaced Porsche 928 parts, ensuring your machine remains spirited for years to come.

Oil Filter

For many, oil filters remain the unsung heroes of engine longevity, but if you know anything about cars, you know you’ll need one of these to keep contaminants out. The high-performance V8 in the 928 demands regular oil changes and filter replacement. 

You can look to the 92810720107 or  92810720105 filters which are specifically made for this model to ensure optimal flow and filtration.

Air Filter

To ensure your V8 engine continues to sing beautifully, you must ensure the supply of clean air. Dust and debris build up over time and can clog the air filter, impacting the joys of crisp throttle response and power delivery. 

To keep the engine breathing freely, owners can check out the Porsche 928 air filter, specifically the 928-4.5L variant, which perfectly matches the car.

Spark Plugs

Ignition is where magic happens, and the spark plugs are the wizards who cast the spell. Over time, the crucial but small spark plug can wear out, leading to misfires, decreased performance, and rough idling.

High-quality spark plugs like the 928-4.5L variant ensure that your engine continues to fire on all cylinders for a reliable start and smooth operation.

Fuel Filter

Everything, including the fuel, has to be clean to keep the 928 running efficiently for a long time. A clogged filter can lead to performance declines and even shut down the engine if not addressed in time. 

For daily usage, avoid reusing old gasoline if it’s contaminated, and ensure the connections are tight to prevent leaks. Regular inspections and timely replacement (every 60,000 miles or four years, whichever comes first) are recommended.

Wiper Blades

Visibility is non-negotiable for a car that doesn’t have to ask twice to be driven in all conditions. Most owners who can’t find top-tier and complete parts tend to buy universal replacement rubber and cut it to fit the existing holder. 

While MacGyvering your 928 sounds like a fun time, if you somehow get it right, you don’t have to worry about that.

The front wiper blades, specifically the Bosch variant for the 928, ensure that your windshield remains clear and provides a safe driving experience even in the harshest weather.

Engine Oil and Lubricants

928 owners have a lot to say about engine oil and lubricants, given their indispensable role in the running of your car. 

Keep in mind the quirks of the V8 engine. Some users have reported varying oil pressures depending on the oil type and condition. It is advisable to keep the pressure around 2.75 to 3.25 bar at idle and ensure it reaches 5 bar at high RPMs. 

It is also prudent to choose oil or lubricants that match your driving frequency and the weather conditions and to keep the type consistent for a rewarding experience.

Handbrake Shoes

The 928 is powerful and thus requires a reliable handbrake, especially when parking on an incline. Some owners have reported that the handbrake shoes can be tricky to adjust properly and may not hold on inclines.

They also wear out faster if frequently used to hold the car on slopes, which calls for regular inspection and timely replacement. 

It is also better to get help from a professional to install it since it’s in a tight space. Some enthusiasts recommend upgrading to higher-quality aftermarket shoes like Brembo for better performance and longevity. 

Brake Pads

When you need to stop a Porsche, you better have the brake pads to do the job. As we have repeated here, ad nauseam, the 928 is a V8 beast tuned to perform at a high level by Porsche’s driven (no pun intended) engineers.

Porsche still provides genuine 928 brake pads for most, if not all, of its car models. If you are searching for front or rear brake pads, you can find genuine replacement parts and aftermarket options like Textar, ABS, and Brembo.

Brake Disc Standard

The brake discs play a crucial role in the overall braking performance. For the 928, you can find standard brake parts from Porsche, ABS, Textar, Sebro, and Zimmerman. 

Looking to owners for insights, we find reports of some uneven wear, often caused by caliper issues or improper installation. Some upgrades you can do include stainless steel braided lines and high-performance brake fluids to enhance the overall system performance.

Upgrade your 928 brakes as a complete unit for an overall improved braking experience, especially if you track the vehicle.

Brake Fluid

The hydraulic system that powers your brakes relies on brake fluid to function properly. Over time, the fluid can absorb moisture and impurities, reducing its effectiveness and potential brake failure. 

Regularly flush and replace the brake fluid using the recommended products for the 928 to ensure that performance is top-notch.

You can also get Porsche 928 brake calipers, high-temperature racing brake fluid from Brembo, PFC, Porsche, Textar, and Sealey, a brake fluid bleeding kit to DIY, and a boiling point tester kit to make sure you get the right fluid.
