Prevents costly airbox explosions, installed with the engine and air box in place. 911 engines since 1973 have had the bad habit of backfiring and blowing a hole an the air box. 911 POP VALVE is installed inside the air box and when a backfire occurs the valve will instantly open and release the backfire pressure. The POP VALVE then automatically closes and the angine continues to run. The POP VALVE has no effect on the performance or fuel mileage.

Understanding OEMatch Air Filters
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original air filters.
OE (Original Equipment) refers to parts matching original specifications for the air filters and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM air filters engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
Air filters trap airborne particles, help keep air–fuel ratios stable and protect pistons, valves and cylinder walls from abrasive contamination. Choice of media and service interval depends on driving conditions, local environment and model-specific intake layouts; inspect the element at service intervals and replace when clogged or damaged.
OEMatch provides a wide selection of Porsche-compatible parts and has catalogued over 4,000 individual part numbers and over 8,700 OE cross-references to support maintenance and repairs. The product range is developed to help owners maintain, restore and use Porsche vehicles across multiple generations.
Benefits Include
- Protects engine internals from dust and abrasive particles
- Helps preserve fuel economy and consistent combustion
- Makes routine servicing straightforward with identifiable part references
Why Air Filters Wear and Fail
- Progressive clogging from dust, pollen and road debris
- Moisture or oil contamination that reduces filtration capacity
- Media degradation from age, heat exposure or mechanical damage
The Importance of Replacing with OEMatch Air Filters
Timely replacement preserves engine protection and consistent performance for Porsche models. Selecting the correct media and correct reference for your vehicle avoids fitment issues, reduces the risk of unfiltered air entering the intake and supports predictable service intervals.
Advantages
- Choice of media types to suit standard service, restoration or performance preferences
- Direct-fit replacements engineered to match original dimensions and tolerances
- Clear part references to assist correct selection for Porsche models
