If your Toyota, Lexus, or Scion is running rough, stalling, or guzzling gas, the mass air flow sensor might be the culprit.

This ISUMO MAF sensor is a direct swap for part numbers MAS4553 and MAS0313.

It’s a 5-blade design, brand new in box, and ready to install.

Helps your engine get the air-fuel mix just right, which means smoother idling, better acceleration, and improved fuel economy.

Fits a bunch of models from Lexus, Scion, and Toyota—just cross-check your OEM part.

Comes with a manufacturer warranty, so you’re covered if anything goes sideways.

Easy install for DIYers: unplug the old one, plug this in, and you’re back on the road.

Don’t let a dirty or failing MAF sensor drag down your ride’s performance.
