    Easy instal

Fits perfectly the install took about 7mins. This replacement cleared the check engine light code PO420 which reads as Bank 1 below threshold and is commonly considered a malfunction of the catalytic converter but in fact more likely than not the issue is one of the oxygen sensors is below the recommended ohms for Subaru Outbacks oxygen sensor should be anywhere from 5 ohms to 10 ohms anything below that the O2 sensor is no good. And my driver side Upstream sensor was reading 4 ohms. Hopefully this helps and good luck.
