Mass Air Flow Sensors From $26.99

4,848+ Applications | Free Shipping | 3-Year Warranty

Your engine needs the right air-fuel mixture to run smoothly, and that's where we come in. Our MAF sensors measure airflow with lab-grade accuracy, sending real-time data to your engine computer so you get maximum power and fuel economy. When yours starts acting up, you'll know it fast.

How to Tell If You Have a Faulty Mass Airflow Sensor

Your check engine light pops on first?usually with codes P0100 to P0104. But you'll feel the problems before you see the light. Rough idling hits you at stoplights as your engine shakes or stalls from incorrect air-fuel mixture. Step on the gas and your car hesitates or stumbles instead of accelerating smoothly.

A faulty mass air flow sensor typically causes your check engine light to come on since your ECU constantly monitors sensor inputs, triggering diagnostic trouble codes in the range of P0100 to P0104. Your fuel economy tanks too?we're talking 15-30% worse gas mileage because your engine runs too rich without accurate sensor readings.

Common MAF Sensor Failure Signs:

? Check engine light: Codes P0100-P0104 tell you the sensor circuit has problems

? Poor acceleration: Engine hesitates when you need power most

? Bad fuel economy: Fuel usage jumps 20-40% as your ECU defaults to rich mixture

? Hard starting: Takes multiple tries to crank the engine, especially when cold

? Black exhaust smoke: Dark smoke means your engine's burning way too much fuel

Mass Air Flow Sensor Replacement Cost

Dealerships charge $200-$500 for MAF sensor replacement?that's parts plus labor. You're paying $100-$350 just for the sensor itself. We sell the exact same quality sensors starting at $26.99, saving you serious cash. Breaking sensor wires requires replacement which can run upwards of $100, so our sensors use the same rugged construction as OEM parts.

Installation takes 15 minutes max. Disconnect your battery, unplug the electrical connector, remove two to four screws, and swap in the new sensor. That's it. You don't need special tools or mechanic skills?just basic hand tools you already own.

Why Choose Our MAF Sensors

We stock sensors for 4,848 different vehicles?cars, trucks, SUVs?basically everything on American roads. Each sensor features platinum or gold-plated elements that measure airflow within 2% accuracy across all temperatures. You get OEM-equivalent performance at a fraction of dealer prices.

Every sensor ships free and leaves our warehouse within 1 business day. We back everything with a 3-year warranty and 90-day free returns. If it doesn't fit or work perfectly, send it back?no questions asked. That's how confident we are in our parts.

Frequently Asked Questions

Can I clean my MAF sensor instead of replacing it?

You should clean your mass airflow sensor either every six months or every time you change your oil, cleaning it when you change your air filter saves time and money. Use only MAF sensor cleaner spray?never touch the sensor wires. If cleaning doesn't fix your issues, replacement is necessary.

How long do mass air flow sensors last?

At the ten-year point (80,000 to 150,000 miles), your vehicle will likely need a new sensor. Sensors don't need regular replacement like oil filters?only replace them when they fail or cause performance problems.

Will a bad MAF sensor damage my engine?

Yes. Running with a faulty MAF sensor causes your engine to run too rich, which dumps excess fuel into your exhaust system. This unburned fuel will destroy your catalytic converter?a $1,200-$2,500 repair. Replace the $27 sensor now to avoid thousand-dollar repairs later.

Do you have the right sensor for my car?

We stock MAF sensors for 4,848 vehicle applications from virtually every manufacturer. Enter your year, make, and model on our site and we'll show you the exact sensor your vehicle needs. All our sensors are guaranteed to fit or you get your money back.

What's your return policy if the sensor doesn't work?

We offer 90-day free returns, no questions asked. If the sensor doesn't fit, doesn't fix your problem, or you're not completely satisfied, send it back for a full refund. We also provide a 3-year warranty covering any defects.
