Product Details

The DENSO 234-4256 is a premium 4-wire heated oxygen sensor engineered to meet strict OE standards for reliable engine performance monitoring. This direct-fit sensor features a 14.8-inch wire lead for easy installation in specific vehicle applications.

Key Features:

  • 4-wire heated design for faster sensor activation and accurate readings
  • Direct-fit replacement ensures proper fit on the first installation
  • Proprietary aluminum oxide coating protects the ceramic element from silicone and lead contamination
  • Precision-manufactured to OE specifications for exact replacement

DENSO oxygen sensors help optimize air-fuel mixture, improve fuel efficiency, and reduce harmful emissions.

Great price and good company to buy from!

I ordered CV axles from Autoplicity and had them in less than a week! Definitely the best prices for quality product on this item. Will be a return customer for sure!

Extremely impressed with Autoplicity!!!! I am a very loyal Amazon customer and ALMOST paid a 20% premium on my Thule bike rack to go with old faithful. Very glad I didn't, as I saved $50 and received my product with free shipping FASTER than Amazon Prime!!!
