2012 Porsche Cayman Filter Part Numbers: Complete Guide

If you own a 2012 Porsche Cayman, you know that keeping up with routine maintenance is essential for performance and longevity. One of the most common DIY tasks is replacing filters—oil, air, cabin, and fuel. But finding the right part number can be confusing, especially with multiple brands and revisions. This guide provides the exact filter part numbers for the 2012 Cayman (base, S, and R models) so you can order with confidence.

Oil Filter Part Number for 2012 Porsche Cayman

The oil filter is critical for engine health. The 2012 Cayman uses a cartridge-style oil filter located in a housing on the engine. The OEM Porsche part number is 948-107-221-00 (or superseded to 948-107-221-01). This filter fits all 2012 Cayman variants: base 2.9L, S 3.4L, and R 3.4L. Aftermarket alternatives that match exactly include:

• Mann W 719/30 – widely used, exact fit
• Mahle OX 189D – includes both filter element and O-rings
• Bosch F 026 407 139 – quality alternative

Make sure you also replace the drain plug washer (P/N 900-123-111-30) and the housing O-ring (P/N 948-107-221-70) for a leak-free seal.

Oil Filter Capacity and Specs

When changing the oil, the 2012 Cayman requires about 7.5-8.0 quarts (depending on engine) of synthetic oil meeting Porsche A40 approval (0W-40 or 5W-40). The filter should be changed every oil change, typically 10,000 miles or once a year.

Engine Air Filter Part Number

The engine air filter keeps debris out of the intake. For the 2012 Cayman, the OEM part number is 997-110-913-03 (or superseded to 997-110-913-04). This pleated paper filter fits all 2012 Cayman models. Aftermarket options:

• Mann C 32 188/1 – premium filtration
• Mahle LX 318/1 – good durability
• K&N 33-2351 – reusable but note that oiled filters may require careful maintenance

When to Replace the Air Filter

Inspect the air filter every 15,000–20,000 miles. Replace sooner if you drive in dusty or dirty conditions. A clogged filter reduces fuel economy and engine power.

Cabin Air Filter Part Number

The cabin air filter (also called pollen filter) cleans the air inside the cabin. The 2012 Cayman uses a standard rectangular filter located behind the glove box. OEM part number is 997-572-021-00 (charcoal) or 997-572-021-01 (non-charcoal). Aftermarket:

• Mann CU 2936 – charcoal, high quality
• Mahle LA 293 – charcoal
• Bosch P 2936 – good choice

Installing the Cabin Air Filter

This is a simple DIY: remove the glove box (two screws), pull out the old filter, note the airflow direction arrow, and slide in the new one. Replace every 20,000 miles or once a year to prevent musty odors and reduce allergens.

Fuel Filter Part Number

The fuel filter for the 2012 Cayman is integrated into the fuel pump module inside the fuel tank. It is not serviceable separately in the traditional sense. The entire fuel pump module (including filter) is part number 997-620-931-01 (superseded). However, some aftermarket kits offer a separate filter element, such as:

• Mann WK 614/1x – inline fuel filter, but verify compatibility
• Bosch 0 450 906 033 – may require additional fitment check

Because replacing the fuel filter requires dropping the tank or removing the module, it is rarely done as standalone maintenance. Typically, it is only replaced if the fuel pump fails. Consult your service manual before attempting.

How to Verify Filter Part Numbers

Before ordering, confirm your specific Cayman model (VIN lookup is best). Cross-reference the OEM number with aftermarket catalogs. Many auto parts websites allow you to search by year, make, model, and engine. Always check that the aftermarket brand explicitly lists compatibility with the 2012 Cayman. If in doubt, stick with OEM for the air and oil filters.

Final Recommendation

For the 2012 Porsche Cayman, stick with Mann or Mahle for oil and air filters—they meet or exceed OEM specs at a lower price. For the cabin filter, Mann CU 2936 is excellent. For fuel, unless you suspect contamination, leave it as part of the pump module. Remember to replace the oil drain plug washer and housing O-rings to avoid leaks. Keeping a log of part numbers and replacement dates will help with future maintenance.

By using the correct filter part numbers, your 2012 Cayman will continue to deliver the driving experience you expect. Always double-check with your local Porsche dealer or trusted parts supplier for any supersession changes.
