3 Reasons to Upgrade to the 2002-05 Hyundai Sonata Catalytic Converter 457023 by MagnaFlow

If you intend increasing the output of your 2002-05 Hyundai Sonata 4Cyl 2.4L by more than 20 percent, you should consider stepping up to the direct-fit MagnaFlow catalytic converter 457023. The flow of the higher volume of exhaust fumes that your engine will produce while putting out more power is likely to be frustrated by your stock catalytic converter because it is not built for performance applications. So your stock converter may be inhibiting your car’s performance. This bolt-on MagnaFlow catalytic converter delivers a higher flow of exhaust gases, which is likely to translate to enhanced performance. You can have this high-flow catalytic converter for just $552. In this article, we will discuss some of its benefits as we consider the following:

1. What is a Catalytic Converter?
2. What are three reasons to upgrade?
3. Why buy the California MagnaFlow catalytic converter 457023?

What is a Catalytic Converter?

A catalytic converter is a metal chamber along with your car’s exhaust system that is designed to change the constitution of exhaust gases to reduce the volume of harmful emissions that your vehicle puts out into the atmosphere. The converter comes integrated with precious metals like platinum, rhodium, or palladium that act as chemical catalysts. When the exhaust gases, which may consist of carbon monoxide, nitrogen oxides, and hydrocarbons, come in contact with these precious metals, they convert into less harmful gases like carbon dioxide and nitrogen.

What are three reasons to upgrade?

Fuel Economy

The HYUNDAI Sonata (2001 - 2004) delivers a combined fuel economy of 25.3 mpg US (9.3 L/100Km). Installing the direct-fit MagnaFlow catalytic converter 457023 onto your vehicle is sure to yield even higher fuel economy. With its clever, compact packaging, this converter features more passages for exhaust fumes to flow through. Hence, it lessens the buildup of exhaust gases in the engine. As a result, your engine won’t work as hard to drive the car as it otherwise would. As a result, it will achieve better [higher] fuel economy.

EPA Carbon Emission Standards Compliance

A high-flow catalytic converter like the MagnaFlow catalytic converter 457023 is better at breaking down raw exhaust fumes to less harmful emissions than your stock catalytic converter. It benefits from low-mass material with higher thermal efficiency, increased surface area contact with the exhaust fumes, and an ideal concentration of expensive rare-metal catalysts. Therefore, you can count on it to convert harmful carbon monoxide, nitrogen oxides, and hydrocarbons to less toxic compounds like nitrogen and carbon dioxide with more excellent proficiency. As such, your car is more likely to comply with your state’s carbon emission standards when equipped with it.

Better Performance

The direct-fit MagnaFlow catalytic converter 457023 can also enable your 2002-05 Hyundai Sonata 4Cyl 2.4L to recover the performance it has lost over time, thanks to the catalytic converter clogging. By making it easier for your car’s engine to discharge exhaust gases, the MagnaFlow catalytic converter 457023 will help to bring back the ideal potency of the fuel/air mixture in your engine’s combustion chambers. Therefore, it will fix your car’s initial performance.

Why buy the MagnaFlow catalytic converter 457023?
