Product Details

The NGK NTK 21571 oxygen sensor (also called an O2 sensor or lambda sensor) is a direct-fit, OE-style replacement. Oxygen sensors are part of the on-board diagnostic system. They send constant closed-loop feedback to the ECU, which helps control the air-fuel ratio and flags possible fuel delivery or catalytic converter problems. A worn sensor can lead to decreased fuel efficiency and increased emissions.

Key Features:

  • Advanced ceramic sensor element with a 3-stage contaminant-resistant plasma jet and deposit trap overcoat that protects against element poisoning
  • Dual-coated platinum interface and thinner ceramic element for fast light-off and response times and good durability
  • OE-specified water-resistant connector and harness accessory hardware for easy installation
  • Engineered for OE fit, form and function, with vibration and thermal shock testing during development

Specifications:

  • Sensor type: narrow band, heated oxygen sensor
  • Thread: M18-1.5 (18 mm), threaded mounting, no flange
  • Wrench size: 7/8 in
  • Wires: 4 wires with 4 blade terminals, square connector
  • Wiring harness: included, 13.25 in long

Cross References: This sensor replaces ACDelco 213-2823, 213-3851, 213-3858 and 213-4576; Bosch 16134, 16449, 16451, 16746, 16828 and 16938; Delphi ES20113; DENSO 234-4259, 234-4565, 234-4566, 234-4818 and 234-4840; General Motors 12590035, 12596688, 12597449, 12616203, 12634064, 12634085 and 12640453; Spectra Premium OS5509; and Suzuki 1821378J10.

Installing a new NTK oxygen sensor helps restore proper fuel control, supports lower emissions and helps maintain fuel economy.

Super pricing, fast shipments, good selection they have it all.

Excellent customer service....<br>fast delivery<br>and good quality parts<br><br>

My second time ordering from Autoplicity. I price shop online and Autoplicity had the lowest price both times. Fast ship with email notifications. Autoplicity will now be my "First" site I go to for my auto accessories. Great job Autoplicity.

Great prices, quick shipping, customer service a bit difficult to reach. But, after reaching customer service, issue was resolved without a problem.

Excellent low price, super fast shipping, and great communication. Top notch seller. Recommend highly!!

I ordered the palm tree license plate frame. I love it! I will definitely shop again for other car accessories!<br><br>

cheapest price, better than summitt or jegs too
