This is a high-quality replacement pollen filter for the factory cabin filter used in Porsche Cayenne (958 series, ~2011–2018) models. This filter captures dust, pollen, odour molecules, and fine particles from incoming air entering the vehicle’s cabin ventilation system. It helps maintain clean, fresh interior air and protects HVAC components from contamination
Fits:
Porsche 958 Cayenne 2011 - 2018
• Location: In the cabin air intake / HVAC housing (behind glove box or cowl)
• Function: Filters incoming air of pollen, dust, odours, and fine particles; keeps cabin air fresh and protects HVAC system
Cabin filters degrade over time as debris accumulates and the odour media saturates. A clogged or aged filter leads to:
• Reduced airflow or blower performance
• Unpleasant cabin odours, especially after rain
• Increased strain on blower motor
• Allergens or particulates entering the cabin
Replace the filter:
• According to Porsche’s maintenance interval (commonly every 15,000–25,000 km or once/year depending on conditions)
• When airflow seems weak or odours persist
• During HVAC servicing or after long environmental exposure (e.g. dusty or polluted environments).
Installing a new filter restores optimal air quality, maintains ventilation efficiency, and preserves the premium cabin experience expected of Porsche vehicles.

The pollen particle filter traps dust, pollen, dirt, and airborne particles before they enter the cabin through the ventilation system. It helps improve cabin air quality, protects the HVAC system from debris, and supports effective heating, ventilation, demisting, and air conditioning performance.
Functions
• Filters incoming cabin air
• Helps trap pollen, dust, dirt, and airborne particles
• Supports cleaner air inside the vehicle
• Helps protect the HVAC blower and ventilation system
• Supports efficient heater and air conditioning airflow
• Replaces dirty, blocked, damp, or damaged cabin filters
• OE Match replacement for routine service and maintenance.
Why Replace This Part?
Pollen particle filters become blocked with dust, pollen, leaves, moisture, and road debris over time. A dirty or clogged filter can reduce airflow, cause musty smells, misted windows, poor demister performance, increased blower noise, or reduced heating and air conditioning efficiency. Replacing the filter helps restore clean airflow and improves cabin comfort.
When to Replace This Part
• Cabin airflow from the vents is weak
• The ventilation system smells musty or stale
• Windows mist up more easily than normal
• The heater, demister, or air conditioning feels less effective
• The blower motor sounds louder due to restricted airflow
• The filter is dirty, damp, clogged, or overdue for service
• Routine service or cabin filter replacement is being carried out.
Where it fits on the car
This pollen particle filter fits within the cabin ventilation / HVAC intake system. It filters air before it enters the passenger compartment through the heater and air conditioning system.

OE Match pollen particle filter for Porsche 986 Boxster and 996 Carrera, Turbo and GT models. This cabin ventilation filter uses the non-activated charcoal type.
Fits
- Porsche 986 Boxster 1997-04
- Porsche 996 1998-05 all models
Check fitment for your specific vehicle (model, year, engine) before ordering.
What This Product Does
The filter captures airborne particles before incoming ventilation air reaches the passenger compartment. It serves the cabin heating and air-conditioning system, rather than filtering the engine's intake air.
Functions
- Traps pollen and airborne dust in incoming air.
- Helps limit debris entering the ventilation system.
- Provides a replaceable filtration element for routine cabin maintenance.
Technical Details
- Part reference: 99657221902.
- Brand: OE Match.
- Filter type: cabin pollen and particle filter.
- Note: Non-activated charcoal type
- Assembly location: particle-filter housing beneath the cowl covering.
Symptoms of Fault
Inspect the filter if ventilation output becomes weak, the cabin develops a stale smell, dust becomes more noticeable or misted windows take longer to clear. These signs can have other causes, so check the filter's condition before assuming replacement will resolve the problem.
Why Replacement Matters
Accumulated dirt can obstruct the filter and restrict ventilation. Renewing a dirty or deteriorated element addresses this service item while allowing the intake area and housing to be checked for leaves, moisture and other debris. OE Match's Porsche-focused replacement programme uses original references and application checks to identify suitable components.
FAQs
Is this an activated-charcoal filter?
No. This version is specified as the non-activated charcoal type; odour-absorbing carbon filtration is not claimed.
When should it be renewed?
Follow the vehicle's maintenance schedule and inspect its condition between services where dusty conditions cause faster contamination.
What should be checked during fitting?
Observe any airflow-direction marking, remove loose debris from the intake area and ensure the element sits correctly inside its housing.
