About this item
Is your check engine light on in your Chevy Silverado or GMC Sierra HD?
This downstream oxygen sensor is likely the fix.
It's a brand new, 4-wire, heated O2 sensor designed for a direct fit on many 2002-2007 models, including the Silverado 2500 HD and Sierra 2500 HD with the 6.0L V8.
It's positioned downstream (Bank 1 Sensor 2) and features a zirconia element with a stainless steel protective sleeve for durability.
It crosses with major numbers like 25024488 and supersedes 25333817.
It's built with double sealing technology to keep moisture out and claims a +150% power gain in control – though we'll just say it'll get your fuel mix right!
Easy install with blade & bullet terminals.
