What This Product Does
This sensor measures intake-air temperature, providing an input used by the engine control system when determining fuelling adjustments. It monitors incoming air rather than coolant temperature, so coolant-gauge or radiator-fan faults should not automatically be attributed to this component.
Functions
- Measures temperature within the intake system.
- Provides temperature information to engine management.
- Supports temperature-dependent fuelling calculations.
Technical Details
- Part reference: 99660611300; brand: OE Match.
Symptoms of Fault
- Implausible or intermittent intake-temperature readings in diagnostic data.
- Engine-management warning or a temperature-signal fault code.
- Rough running, difficult starting or increased fuel consumption where incorrect temperature information affects fuelling.
Why Replacement Matters
A confirmed sensor fault can leave engine management working with incorrect temperature information. Replacing the defective component addresses that input, but connector corrosion, damaged terminals and wiring faults should be investigated first because they can produce similar symptoms.
FAQs
Does a fault code prove the sensor needs replacement?
No. Use the code alongside live readings and electrical checks before deciding which component is responsible.
What should be inspected first?
Check the connector, terminals and nearby wiring for damage or corrosion, then test the signal using the appropriate vehicle-specific procedure.
Can similar-looking sensors be interchanged?
Appearance alone does not establish compatibility. Match reference 99660611300 and the relevant model, engine and production-year details.

OEMatch Temperature Sensor — Fit, Function, Confidence
OEMatch supplies temperature sensor replacements for Porsche models, chosen to support accurate engine management and safe operation. Many owners search for genuine or OEM temperature sensors; these are direct-fit alternatives designed to match the original form, fit and function.
Available Types
- Coolant temperature sensors
- Oil temperature sensors
- Intake air temperature (IAT) sensors
- Exhaust gas temperature (EGT) sensors
Understanding OEMatch Temperature Sensor
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original temperature sensor. OE (Original Equipment) refers to parts matching original specifications for the temperature sensor and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM temperature sensors engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models. Temperature sensors monitor coolant, oil, intake air and exhaust temperatures and feed real-time data to the engine control unit to regulate fuelling, ignition timing, emissions systems and cooling fan operation. Accurate readings support consistent performance, emissions compliance and fuel economy in varying load and climate conditions.
Benefits Include
- Accurate temperature readings for ECU adjustments
- Improved fuel economy and engine efficiency
- Protection against overheating and related engine damage
Why Temperature Sensor Wear and Fail
- Thermal fatigue from repeated heating cycles
- Corrosion or oxidation at electrical connectors
- Contamination from coolant or oil damaging sensing elements
The Importance of Replacing with OEMatch Temperature Sensor
Timely replacement of a faulty temperature sensor helps maintain correct engine management and prevents symptoms such as fluctuating gauge readings, rough idle, reduced fuel economy or overheating. Using replacements selected for Porsche applications reduces the risk of misreported temperatures and supports consistent ECU response across operating conditions, contributing to engine protection and reliable vehicle operation.
Advantages
- Designed to match original-spec dimensions where applicable
- Compatible with factory sensor locations and mounting points
- Available for a wide range of Porsche models and engine types
Support & Advice
These items affect safety-critical systems. Installation should be carried out by a qualified technician following model-specific procedures and torque settings. Use calibrated tools and specified fasteners; if sensors are part of systems with hidden sensors or require recalibration, seek professional installation and follow Porsche-specific guidance.
