Infiniti Catalytic Converter Customer Reviews

Fit without any issues ! Can't say anything negative !

Purchased on Mar 02, 2021
I am very impressed with the part. It fit perfectly without any issues at all. My check engine light has cleared and my car is now passing emissions. I have a 2005 Infiniti G35 Sedan. Just note that you need to supply your own hardware.

Soon as all 4 Catalytic Converts were Installed my Nissan Armada instantly was back to running like new. I’ve got 225,000 miles on the vehicle & I am amazed by spending over $700 for all 4 Catalytic Converters how great the SUV now runs. It was a small price to pay $700 parts +$800 Mechanics labor totaling $1,500 Compared to replacing the vehicle. With a $600+monthly payment to replace that vehicle. Thank you Carparts.com for having the parts when needed. One thing I wished was to expedite the order because it was a large order Carparts.com only offered Fed-x Ground shipping. I would have paid the extra money in shipping to expedite the parts instead of waiting an entire week. Other than that the service was great

Infiniti Catalytic Converter Guides

The Infiniti catalytic converter is a valuable part of the emission control system of your vehicle, helping to reduce the level of pollution it sends into the air we breathe. The engine produces a variety of chemicals as byproducts of the combustion process that it uses to produce the power that propels your vehicle. Several of these chemicals are quite harmful to humans and animals, and some are contributors to the growing problems of smog and acid rain.

The Infiniti catalytic converter is located in the exhaust system of your vehicle to process the exhaust gasses that are produced by the combustion process, sifting out a portion of these chemicals to reduce the amount of toxic fumes that are allowed to flow out of the vehicle tailpipe into the environment. This task is accomplished with a ceramic honeycomb style structure that makes up the interior of the Infiniti catalytic converter, which is coated with catalyst metals. These metals cause a chemical reaction with the molecules of these hazardous chemicals as they make their way through the Infiniti catalytic converter, which causes some of these molecules to burn up and others to remain trapped inside. This significantly reduces the amount of toxins that are allowed to exit the vehicle into the air, reducing air pollution.

The Infiniti catalytic converter is an important safeguard, keeping the pollution produced by the millions of vehicles on today's busy roadways to a minimum. We carry a selection of Infiniti catalytic converter replacements at good deals. 

Infiniti Catalytic Converter Buyer's Guide

Summary

  • Infiniti is the luxury vehicle brand of Nissan.
  • Infiniti produces genuine parts and accessories in-house.
  • OEM parts are created by the automaker or any of its licensed third-party suppliers.
  • OE replacement Infiniti catalytic converters can work just as well as OEM.
  • When shopping for a catalytic converter, consider fitment and cost.

Infiniti is the luxury vehicle line of Nissan. The production of its models is spread out in Nissan factories and some of its licensed factories around the world. Infiniti vehicles are known to possess sophisticated designs and exquisite interiors that could rival their more expensive counterparts without the expensive price tag.

Your catalytic converter, which is responsible for turning toxic gases into less harmful ones, should be replaced once it gets worn out or damaged. It typically lasts for 10 years or longer, but this is relative to your usage and the environment it is exposed to. If you’re looking to replace your Infiniti G35 catalytic converter or any Infiniti catalytic converter, read the guide below so you can make a more informed buying decision.

Who manufactures Infiniti parts?

Infiniti produces its own parts under the name Genuine Infiniti Parts. These parts are factory-approved and are designed to fit seamlessly so that Infiniti users can enjoy the comfort and luxury that come with Infiniti vehicles for years on end.

OEM Parts vs OE Replacement Parts

You might have encountered the terms OEM parts and OE replacement parts while shopping for automotive components. While they are frequently used interchangeably at times, there is a significant difference that sets them apart from each other.

OEM or Original Equipment Manufacturer parts are produced by the vehicle manufacturer or any of its third-party contractors. Because they are licensed by the automaker and have the exact same fit as the parts that came with your vehicle, OEM parts are priced at a premium.

OE or Original Equipment replacement parts are also manufactured with the blueprint of the vehicle they are intended for. However, they come at a lower cost. Despite being produced by third-party contractors, they can be suitable alternatives to OEM parts when bought from a credible source.

Are OE replacement Infiniti catalytic converters as good as OEM?

If purchased from a good source, Infiniti catalytic converters can perform just as well as OEM. This is because reliable shops often screen the items they offer for fit and quality as they wouldn’t be caught dead selling ill-fitting or substandard parts.

CarParts.com has a wide range of expertly-chosen Infiniti parts and accessories in its catalog. So finding a part with the best fit, may it be a 2005 Infiniti G35 catalytic converter or a 2000 Infiniti G20 catalytic converter, will be fool-proof.

Choosing the Right Infiniti Catalytic Converter

Some of the things you should consider when buying a catalytic converter are fitment and cost. First, ensure that the catalytic converter you are getting is compatible with your vehicle. To do this, you need to note the make, model, and model year of your ride when searching for the part that you need.

When searching online, you can indicate those details along with the part you are looking to buy to get a better match. For example, you can type “2001 Infiniti QX4 catalytic converter replacement” or just “2001 Infiniti QX4 catalytic converter” on the search bar.

Another thing you should also factor in is the cost. OEM Infiniti catalytic converters are more expensive than their OE counterparts. So check which part type best fits your budget.
