Lada Niva Catalytic Converter 2123 (2002-2020)

The Lada Niva Catalytic Converter 2123 is a 3-way catalytic converter designed for the 1.7 MPFI petrol engine (engine code 21214) of the Lada Niva II model 2123. It regulates emissions such as carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxides (NOx), complying with Euro 2 to Euro 4 emission standards depending on the vehicle version. It is positioned in the front part of the exhaust line, before the silencer, and is paired with a regulating oxygen (lambda) sensor.

Key technical details include:

• Vehicle: Lada Niva II (type 2123)
• Engine: 1.7i petrol, engine code 21214 (MPFI - multipoint fuel injection)
• Power output: 80 hp (59 kW) to 83 hp (60-61 kW) depending on the European version
• Production period: since approximately September 2002
• Euro emission standard: mainly Euro 4 for recent models, earlier models may be Euro 2 or Euro 3

These specifications ensure compatibility with a range of Lada Niva 2123 models and meet various emission regulations.

The catalytic converter for the Lada Niva 2123 is a classic 3-way type placed at the front of the exhaust system:

• Positioned directly after the exhaust manifold (collector)
• Located before the first silencer (muffler) in the exhaust line
• Equipped with an oxygen (lambda) sensor fitted upstream of the catalytic converter for regulating emissions

Some versions come with exhaust pipes integrated with the catalytic converter as a unified assembly.

Premium catalytic converters for Lada Niva 2123 are designed with quality and durability in mind:

• Manufactured from high-grade stainless steel INOX 409 to resist corrosion and heat
• Use high-quality ceramic monoliths with honeycomb structures for effective catalytic reaction
• Special coating with rare metals to improve performance and longevity

These features ensure effective emission reduction and long service life compatible with OEM standards.

Yes, for older Euro 2 compliant Lada Niva 21214 models, replacement pipes without catalytic function ("decata" pipes) are available:

• Usually 375 mm in length with two bolt flanges on each side for easy installation
• Used typically for off-road or competition use where emissions regulations do not apply

Note that use of these pipes in regular road traffic may be restricted by local emission laws.

The oxygen sensor is mounted before the catalytic converter and plays a crucial role in exhaust emission control:

• Measures oxygen levels in exhaust gases to help the engine control unit optimize fuel-air mixture
• Enables regulation of emissions and protects the catalytic converter from damage by improper combustion
• Typical sensor includes a heating circuit and signal wires (usually 4 wires total) with lengths around 1010 mm

A malfunction in this sensor or catalytic converter can trigger diagnostic trouble codes related to emissions.

Customers can choose between OEM and aftermarket catalytic converters for the Lada Niva 2123:

• OEM parts: Guarantee exact compatibility, original geometry, certified performance, and manufacturer approval
• Aftermarket parts: Often more affordable, made of stainless steel INOX 409 with high-quality monoliths, but quality may vary by brand

Choosing the right part depends on budget, availability, and specific vehicle requirements.
