Buying Guide

Confirm OEM part number fitment

Match the vehicle’s OEM or OE-style part number (e.g., 22680-AA310 or 25318411) to ensure correct electrical connector and mounting alignment

Check vehicle make and engine compatibility

Select sensors listed for your brand and engine size—options here cover Toyota/Lexus/Mazda, GM/Chevy/GMC/Cadillac, Honda/Acura, and Subaru applications

Prefer direct-fit assemblies for simpler swaps

Direct-fit MAF assemblies replace the entire housing and sensor, reducing calibration steps versus standalone elements and easing installation

Evaluate connector type and pin count

Verify the sensor’s electrical connector and pin configuration match your harness to avoid wiring adapters or splicing

Use customer ratings and value score

Consider models with consistent user ratings (most in this list are ~4.2–4.4★) as an indicator of fitment reliability and value under $50
