Product Details

The Bosch 15637 Oxygen Sensor is a premium heated 4-wire oxygen sensor designed for post-catalytic converter installation. This universal O2 sensor features Bosch's advanced Super Class technology with dual-stage filtration to ensure extended service life and optimal engine performance.

Key Features:

  • Premium ceramic element constructed with 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 signals to the engine's emission control computer
  • Dual-filter system doubles protection against exhaust gas contamination for extended sensor life
  • 4-wire heated design with 32.7-inch wire length for flexible installation
  • OE-style silicone boots ensure proper fit, function, and appearance
  • Direct plug-in design requires no cutting or splicing
  • Helps prevent premature catalytic converter failure by maintaining optimal air-fuel ratios
  • Rigorously tested for accurate performance and improved fuel efficiency

This downstream oxygen sensor mounts after the catalytic converter and provides critical feedback to your vehicle's ECU for emissions control and fuel economy optimization. Designed as a direct OE replacement, the Bosch 15637 installs quickly without modifications.

It was fast and it was correct

Very pleased with timely delivery and product.

Great price

Fast and easy

Easy checkout, great value Thanks

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.

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.

Exact product as promised with the best price on the internet. Product shipped fast and had a tracking number to keep me up to date on my order. I would order from again without hesitation and will tell friends.

Ordered an ARP ring compressor, best price I could find online, Fast shipping A++
