Porsche Boxster service: key facts

Routine service items

These are the items covered in a standard service. Most garages include oil, oil filter and a basic inspection. The rest are typically checked or replaced on a schedule.

Service itemIntervalTypical cost
Engine oil and filter
Porsche specifies 20,000km (12,500 miles) intervals but specialists universally recommend 6,000-9,000 miles for M96 engines due to IMS bearing and bore scoring risks.
986, 987, 981
9,000 miles or 1 year
£120–£180
Dealer: £200–£280
Air filter
Replace every 2 years or 20,000 miles. Dirty air filter reduces power and fuel economy on naturally aspirated M96 engines. K&N performance filters available but require regular cleaning.

20,000 miles or 2 years
£40–£80
Dealer: £70–£120
Cabin pollen filter
Located behind glove box. Replace every 20,000 miles or when air conditioning efficiency drops. A blocked filter forces the blower motor to work harder and can lead to premature failure.
