Spectra MA187 Premium Mass Air Flow Sensor without Housing

The Spectra Premium MA187 is a 100% new mass air flow (MAF) sensor engineered to meet or exceed Original Equipment (OE) specifications for fit, form, and function. Designed as a direct-fit replacement, this sensor restores accurate air intake measurement to the engine management system, helping maintain proper fuel-air ratios, stable idle, and consistent engine performance.

Key Features:

• Ceramic circuit board construction with premium-grade silicon coating for protection against extreme underhood temperature fluctuations and road vibrations
• All-platinum resistance thermometer sensors deliver faster signal response and superior measurement consistency
• OE-quality ceramic PC board with superior heat dissipation properties ensures long-term performance consistency
• 6-terminal male blade connector with rectangular connector shape for direct plug-and-play installation
• Plastic housing — sold without housing for applications requiring sensor-only replacement
• Manufactured under strict quality control in a dust-free environment to ISO 9001 and TS16949 standards
• Each unit is tested to verify real-world performance before shipment
• Backed by a Limited Lifetime Warranty

Cross-reference part numbers include Cardone Reman 7450028, CARQUEST 641846, and Echlin XTP450028. Replacing a faulty MAF sensor can resolve symptoms such as rough idle, poor fuel economy, and incorrect air-fuel mixture — and is recommended alongside an air filter change for best results.
