| More than 20 years ago, Bosch developed the heated Thimble Type Oxygen Sensor. Since that time, Bosch has improved and updated these oxygen sensors to make them more effective, more durable and easier to install. Bosch Premium Thimble Type Oxygen Sensors utilize an electrical heating element inside the thimble-shaped end to bring the sensor up to operating temperature in less than a minute. The patented thimble ceramic element features the Bosch patented Platinum Power Grid and the patented Bosch Double Layer Protection system for optimized sensing and peak performance, and maximum service life. Its protection tube ensures 100% accurate sensor performance, while its double laser-welded stainless steel body is totally submersible to seal tight and protect against contamination for long life. Coated threads make installation easy. |
