Description

The Denso 234-4449 is an OE-identical oxygen sensor. It features a Zirconia sensor type with a thimble design. This sensor is heated and has a 4-wire configuration with an OE type connector and a threaded mounting type.

The construction includes a stainless steel housing that resists corrosion and contamination. A porous PTFE filter allows atmospheric oxygen to enter while preventing contaminants from entering the casing. Denso oxygen sensors meet or exceed OE specifications, with an aluminum-oxide trap layer to protect against silicone and lead poisoning.
