CRC Mass Air Flow (MAF) Sensor Cleaner - 11 oz Aerosol, Fast-Drying, Plastic-Safe

CRC 05110 Mass Air Flow Sensor Cleaner is a fast-drying aerosol spray formulated to safely remove deposits from MAF sensors and restore accurate airflow readings.

Dirty mass air flow (MAF) sensors disrupt engine air metering, which can cause rough idling, reduced fuel economy, and inconsistent performance. CRC's 11-ounce MAF sensor cleaner is designed specifically to dissolve oil, dust, and carbon build-up on delicate sensor elements without leaving residues or harming plastic housings. It evaporates quickly so you can clean and reinstall the sensor with minimal downtime.

How does this cleaner protect delicate sensor components?

CRC's formula is engineered to strip contaminants without mechanical scrubbing, which helps avoid bending or breaking fine sensor wires and filaments. The solvent is plastic-safe, so it won't degrade common sensor housings when used as directed.

• Non-abrasive spray reaches tight sensor elements.
• Plastic-safe formulation to prevent housing damage.
• Dries in seconds, leaving no conductive residue.

Will using this product improve drivability or fuel economy?

Cleaning a fouled MAF sensor can return the sensor to accurate airflow measurement, which helps the engine computer correct fuel delivery. Users often notice smoother idle, better throttle response, and potential fuel-efficiency gains when the sensor reads correctly again.

• Helps restore proper air/fuel mixture control.
• Can reduce hesitation and rough idling caused by misreads.
• Supports consistent engine performance after cleaning.

How should I use CRC MAF Sensor Cleaner for best results?

Remove the sensor or access the sensor element per your vehicle manual, then spray the cleaner directly onto the sensing element from a short distance. Allow the solvent to evaporate fully before reinstalling the sensor; do not touch or scrub the element.

• Follow vehicle service instructions for sensor removal or access.
• Spray evenly over the sensing wires/film; avoid physical contact.
• Wait for complete evaporation—seconds under normal conditions—before reassembly.

Is this product compliant with environmental regulations?

CRC 05110 is effective and fast-drying, but it is not VOC-compliant for California or some OTC jurisdictions. Always check local regulations before use and dispose of the can according to local hazardous-waste rules.

• Not VOC-compliant for California and certain OTC areas.
• Use in well-ventilated areas and follow safety directions on the label.
• Store upright and keep away from heat and open flame.

Who is this for? CRC 05110 Mass Air Flow Sensor Cleaner is aimed at DIY mechanics, professional technicians, and vehicle owners who want to maintain accurate engine air measurement without risking damage to fragile MAF elements. It suits routine maintenance, troubleshooting drivability issues, or prepping a sensor after an air-filter service. If you need a fast, residue-free cleaner that is safe on common plastics and designed specifically for MAF components, this 11-ounce aerosol is a practical choice.
