If you own a 2001 or 2002 Toyota 4Runner with the 3.4L engine, and it's a California Emissions vehicle, these are the catalytic converters you need.
This set from Mac Auto Parts includes both the front and rear converters for a complete replacement.

They are 100% EPA compliant, so you can be sure they meet the required standards for emissions control.

These are designed as a direct bolt-on replacement—no drilling or modifications needed, just unbolt the old ones and bolt these in.

They come with the necessary seals and are built from durable alloy and mild steel, with ceramic and platinum substrates for efficient conversion.

The manufacturer part number is 25124.

Just a heads-up: these are specifically for vehicles with California Emissions only, and they cannot be shipped to California or New York due to state-specific regulations.
They're made in the USA and come with an incredible 10-year warranty.

A reliable, long-lasting solution for keeping your 4Runner clean and legal.
