Genuine Porsche Spark Plug Set — 356, 356 A, 356 C/SC & 912 — Set of 4 — BERU 14-5AU

The 356 is where everything began. When Ferry Porsche built the first 356 in 1948, he created not just a car but a philosophy — lightweight, driver-focused, and engineered with a purity of purpose that has defined every Porsche since. The air-cooled flat-four that powered the 356 through its entire production run and carried over into the early 912 is one of the most historically significant engines in automotive history — modest in displacement, honest in character, and deeply connected to the driver. From the earliest 1950 models through the final 912s of 1969, these cars are the foundation of everything Porsche stands for.

This is the factory spark plug set for the 356 and early 912 — four BERU 14-5AU plugs, the correct factory specification for these air-cooled flat-four engines, sourced through an authorized Porsche dealer.

About the Plugs These are BERU 14-5AU plugs — the factory-specified ignition component for the 356 and 912 flat-four. Four plugs per set, correct for all compatible models listed below.

When Should You Replace Them? Replacement intervals vary depending on driving conditions, engine tune, and maintenance history. Given the age and significance of these vehicles, we strongly recommend consulting a qualified Porsche specialist or your factory documentation to confirm the correct service interval for your specific car.

Why Genuine Porsche? The car that started it all deserves ignition components that meet the factory specification exactly. These are the correct BERU 14-5AU plugs, sourced through an authorized Porsche dealer, specified for the flat-four that powered Porsche's most historically important early road cars. For vehicles of this significance, there is simply no substitute.

Warranty

Porsche Parts Warranty Information — Suncoast Porsche

Understanding your warranty coverage is important. Below is a complete overview of warranty terms for Genuine Porsche OEM parts, aftermarket parts, and closeout items purchased from Suncoast Porsche and SuncoastParts.com.

Warranty Coverage by Product Type

Genuine Porsche OEM Parts — 2-Year Warranty

All Genuine Porsche OEM parts purchased from Suncoast Porsche or SuncoastParts.com come with a 2-year, unlimited mileage, parts-only warranty beginning on the date of purchase.

If your parts are installed at an authorized Porsche Service Center, both parts and labor warranty coverage may apply if the part is deemed defective within the 2-year warranty period. Coverage varies by location — please check with your local Porsche dealer prior to installation to confirm their specific warranty participation, as each Porsche Center is independently owned and operated.

Important warranty notes for online purchases:

Labor, diagnostic, and installation fees are not covered when parts are purchased online from SuncoastParts.com or Suncoast Porsche, unless the parts are installed by an authorized Porsche Service Center
Warranty claims must be processed in person at an authorized Porsche Service Center
Warranty service is honored at any authorized Porsche dealer in the United States, however some dealers may decline warranty claims for parts purchased online or from another dealership — always verify with your local dealer before installation
If a warranty claim is approved and the part was not installed by a Porsche Service Center, installation of the replacement part remains the customer's responsibility
Suncoast Porsche and SuncoastParts.com are not liable for any diagnostic, labor, or installation fees charged by another Porsche Service Center

Aftermarket & Performance Parts

Warranty coverage for aftermarket and performance parts varies by manufacturer. Most carry a 1-year limited warranty. Contact us for specific warranty details on any aftermarket product. Please note that diagnostic time and labor costs for warranty replacements are not covered.

Take-Off & Closeout Parts

All take-off and closeout parts are sold as-is with no warranty and are not eligible for return. Pricing on these items reflects their as-is condition.

What This Warranty Does Not Cover

The following situations and conditions are explicitly excluded from warranty coverage:

Improper Installation or Misuse — Damage resulting from incorrect installation, negligence, unauthorized alteration, or accident. This includes any use in racing, competition, or motorsport applications
Lack of Proper Maintenance — Damage caused by failure to follow the vehicle's recommended Maintenance Schedule, or failure to use the correct fluids, fuel, oil, or lubricants as specified in the Owner's Manual. Proof of proper maintenance is the owner's responsibility — retain all service receipts in case questions arise
Consequential or Economic Losses — Towing fees, rental vehicles, loss of use, loss of time, inconvenience, or any other indirect economic losses
Vehicles Outside the USA & Canada — Parts installed on vehicles registered or primarily operated outside of the United States or Canada are not covered under this warranty

How to Obtain Warranty Service

Installed by an Authorized Porsche Dealer

If your parts were originally installed by an authorized Porsche dealer, warranty repairs may be performed by that same dealer or any other authorized Porsche Service Center in the United States. Please allow a reasonable timeframe for repairs after delivering your vehicle to the dealership.

Installed by an Independent Repair Shop

Please be aware: All warranty claims must be inspected, performed, and documented by factory-trained Porsche technicians at an authorized Porsche dealership. Work performed at an independent repair shop does not qualify for warranty consideration. If warranty coverage is a priority, we strongly recommend having your parts installed at an authorized Porsche Service Center.

Documentation Requirements for Warranty Claims

To process a warranty claim, the servicing Porsche dealer will require:

Your original sales receipt or order confirmation from SuncoastParts.com or Suncoast Porsche
A completed warranty certificate
Proof of proper vehicle maintenance history (if applicable)

Suncoast Porsche retains sales records on file for two years. If you need a copy of your receipt, contact us and we will provide it promptly.
