Product Details

The Bosch 13523 Oxygen Sensor is a premium 4-wire heated oxygen sensor designed to deliver accurate air-fuel ratio readings to your vehicle's engine control computer. Built with Bosch's Super Class technology, this sensor ensures optimal engine performance, improved fuel efficiency, and reduced emissions.

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 delivery for extended sensor life
  • Dual-filter design provides double protection against exhaust gas contamination
  • 4-wire heated design for faster response time and accurate readings in all operating conditions
  • 17.9-inch wire length for flexible installation
  • OE-style silicone boots ensure proper fit, function, and appearance
  • Direct plug-in design—no cutting or splicing required
  • Rigorously tested for reliable performance while optimizing fuel economy

This downstream oxygen sensor mounts after the catalytic converter and helps prevent premature catalytic converter failure by monitoring exhaust emissions. Designed as a direct OE replacement, the Bosch 13523 provides the quality and reliability you expect from the world's leading oxygen sensor manufacturer.

Word

I ordered a hitch off of this site for Christmas, I have never heard of it nor did I know how they were, but they are great! Got my package in I'd say 4 days, very fast and it was exactly what I wanted! Only down fall was they charged me 3 times and I was short 150$ for a few days. I got my money back and I would definitely order again.

Smooth transaction, very pleased
