Secondary Air Injection Smog Valve 25710-31022 for Toyota Tacoma V6 4.0 SAI

Secondary Air Injection Smog Valve for Toyota

This emission control valve regulates fresh air flow into the exhaust system, replacing part number 25710-31022.

Overview

This secondary air injection smog valve works to lower vehicle tailpipe emissions during cold engine starts. Designed for vehicle owners needing to resolve engine diagnostic codes and pass emissions testing, this secondary air injection smog valve provides precise air routing. Replacing a faulty secondary air injection smog valve protects downstream exhaust components from premature soot accumulation.

Good To Know

Q: What symptoms indicate a failing SAI smog valve? A: A lit check engine light, failure to pass smog checks, or a noisy air pump during cold starts are primary indicators of a sticking valve.

Q: Can moisture damage this valve? A: Yes, exhaust condensation can accumulate inside the valve body over time, which is why this model is built with moisture-resistant internal seals.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
