Product Details

The Bosch 15668 Oxygen Sensor is an OE-replacement heated oxygen sensor designed to deliver precise emissions control and extended service life. This universal 4-wire heated sensor features Bosch's patented dual-filter system that protects against exhaust contamination, ensuring accurate voltage signals to your engine's computer.

Key Features:

  • Premium ceramic technology incorporating Zirconium or Titania and Yttrium for superior protection against mechanical and thermal shock
  • Patented catalytically activated fine particle filter prevents contamination and ensures precise voltage output
  • Dual-filter design doubles protection against exhaust gas contamination for extended sensor life
  • 4-wire heated design for faster response and reliable performance in all operating conditions
  • 11.2-inch wire harness with direct plug-in connection—no cutting or splicing required
  • OE-style silicone boots ensure proper fit, function, and appearance
  • Designed for installation before the catalytic converter

Bosch oxygen sensors are rigorously tested to deliver precise air-fuel ratio monitoring, helping prevent premature catalytic converter failure while optimizing fuel economy and reducing emissions. This sensor meets or exceeds OE specifications for reliable, long-lasting performance.

Autoplicity had the lowest price by far and shipping was very fast (ordered Wednesday evening, arrived Saturday morning). I will definitely order from Autoplicity again!

Very pleasant order over the phone. Gentleman was smart, cheerful and helpful.

Great Experience

Just what you want from a merchant but don't expect; fast, courteous service and attention to the details of your order. I'm a happy consumer. Thank you, Autoplicity. I'll be back.

Autoplicity cares about there customers. I ordered a flash programmer and got to the last page and never got a confirmation of the order. I used the website chat and talked to somebody about it right away. So I ordered again and got a conformation. But both went though. Autoplicity called me next day a.m. to see if I made a mistake. Thanks for letting me know and correcting to one order. Saved me from shipping back a product I dind't need.

Good products with low prices. Easy website and pament options.
