AutoMechanics MAF Sensor: Compatible with Nissan Altima and Sentra
For around $50 to $150, this MAF sensor is a no-brainer for keeping your 2002–2003 Nissan Altima or Sentra with a 2.5L engine running smoothly. It’s the brain’s air traffic controller, measuring every breath of air that enters the engine to fine-tune fuel injection and combustion. Get it wrong, and you’re looking at rough idling, lousy gas mileage, or that dreaded check engine light. Swap it out, though, and things snap back into place—better fuel economy, cleaner emissions, and acceleration that doesn’t hiccup. Installation? A cinch. Grab a screwdriver, maybe a socket set, and you’re done in minutes. Whether you’re a weekend warrior or a pro on the clock, this part is a quick fix for a common headache.
