Product Details

The Bosch 11-78-7-595-353 is an OEM-quality upstream oxygen sensor designed to monitor exhaust gases before the catalytic converter. This pre-catalyst sensor plays a critical role in maintaining optimal engine performance by measuring oxygen levels in the exhaust stream and sending real-time data to the engine control unit for precise air-fuel ratio adjustments.

Key Features:

  • 320mm cable length for proper installation reach
  • Constructed with zirconium and yttrium oxide elements for durability under high-temperature conditions
  • Direct OEM replacement ensuring exact fit and reliable performance
  • Helps optimize fuel efficiency by maintaining ideal combustion ratios
  • Reduces harmful emissions to meet environmental regulations
  • Extends catalytic converter life by preventing damage from incorrect air-fuel mixtures

This genuine Bosch oxygen sensor is engineered to withstand the intense thermal and chemical stress of exhaust system environments. Replacing a worn or faulty O2 sensor restores proper engine management, improving throttle response, fuel economy, and overall drivability while eliminating check engine light codes related to oxygen sensor circuit malfunctions.

I recently needed head bolts for my 408 stroker motor that I'm building. I searched the Internet and Autoplicity had the ARP Head Bolts that I needed. Great price and quick shipping. Will definitely buy from again!!

Great price..easy-to-use shopping

Easy to find the right part and place an order.

Fast & easy

I was lowering my Mustang and I was looking for a good deal. I looked around online and I found Autoplicity. I was surprised with the prices I saw. I thought it was another one of those fake websites that just take youre money and never respond, so I took the chance and ordered anyway. Dont be fooled by the cheap prices. This place is legit. Fast shipping and the package was packed so neat and looked great when it got here. Buy from these guys if you want to get a good deal. I highly recommend them.

Thanks
