URO 11537502525PRM Engine Cylinder Head Temperature Sensor Premium Replacement

The URO Parts 11537502525PRM is a premium-grade replacement engine cylinder head temperature sensor designed as a direct-fit substitute for the original equipment part. Cross-referencing BMW OEM part number 11-53-7-502-525, this sensor is engineered to restore factory-level performance and reliability.

How It Works:

The cylinder head temperature (CHT) sensor monitors the thermal state of the engine cylinder head and transmits that data to the engine control module (ECM). The ECM uses this information to calculate optimal fuel delivery, ignition timing, and other critical engine management functions, helping protect the engine under varying operating conditions.

Key Features:

• Direct-fit OE replacement — engineered to match original equipment specifications for a plug-and-play installation
• Premium construction — built to withstand the harsh thermal and chemical environment of the engine bay
• Precise signal output — accurate temperature readings support correct ECM calibration for fuel trim and timing
• OEM cross-reference: BMW 11-53-7-502-525 / 11537502525
• Manufactured by URO Parts, a trusted supplier of European vehicle replacement components

A faulty or failing cylinder head temperature sensor can trigger a Check Engine light, cause poor fuel economy, rough idle, hard starts, or reduced engine power. Replacing the sensor with a quality URO premium unit restores accurate temperature monitoring and proper engine management.
