Brand-new Denso OE type one-wire oxygen sensor for all 1984-1987 Vin 7 Buick Grand Nationals and Turbo Regals.
This ultra-fast reacting oxygen sensor features the new longer lasting "trap-layer" technology and comes complete with instructions and a tube of copper anti-sieze thread compound for a perfect installation.
Denso oxygen sensors are coated with a special formulation of aluminum oxide to trap impurities outside of the sensing element. These ultra-fast reacting oxygen sensors are rated twice as resistant to lead or silicone poisoning and last up to 5 times longer than any older conical or "thimble-type" oxygen sensors.
As with ANY oxygen sensor, this part is not recommended for use with leaded fuels.
This part will ship in its original packaging as pictured.
