Before ordering, just check that the plug on your old sensor matches the one in our pictures—different years can have different connectors.
GRIZZLY AUTO built these with high-temp materials that respond fast.
The stainless steel body is double laser-welded, so it's fully sealed and can take moisture without failing.
That means a longer life and fewer replacements down the road.
An accurate O2 sensor keeps your fuel ratio dialed in, which means better economy, smoother power delivery, and less strain on your engine.
Each unit is tested before shipping, and if you've got questions, just drop us a line.
