Hey Toyota RAV4 owners! If your check engine light's on or you're noticing worse gas mileage lately, it might be time for a new upstream oxygen sensor. This ACROPIX sensor is a direct fit for your 2006-2012 RAV4 with the 3.5L V6 engine. It matches the OE numbers 8946742080, 894670R010, and 8946742050, so you know it'll plug right in. Made to handle the heat and stuff under your hood, it's got a 4-pin connector, measures about 54.5 cm long, and the threads are M18x1.5. They even pre-coated the threads to make installation way easier – no fighting with rust or seizing. Swapping out a tired O2 sensor can seriously help. Think better fuel economy, smoother engine performance, and fewer weird idle issues. Just remember, this is a quality aftermarket part, not the original Toyota piece. It comes as a single sensor, ready to go. Perfect for a weekend DIY project if you're handy, or for your mechanic to slap in quick. Keep your RAV4 running right without breaking the bank!
