Secondary Air Check Valve Baxzl Metal Design

Description

Product Overview

The Baxzl Secondary Air Injection Check Valve is engineered to meet OEM standards for emission control systems in mid‑size SUVs and crossovers equipped with a 4.2L L6 engine. Constructed from high‑grade machined metal, the valve offers superior corrosion resistance and structural integrity. It features a flare‑type inlet and outlet for a secure, leak‑proof connection, and its compact dimensions (9.17 x 6.46 x 6.34 inches) allow easy integration into tight engine bays. Weighing just 2.29 pounds, the unit balances durability with lightweight design, ensuring minimal impact on overall vehicle performance.

Usage

Designed for direct replacement of OEM part numbers such as 12575655, 214‑2222, and 12619128, this valve fits GMC Envoy SLE/SLT (2004‑2005), GMC Envoy XL, GMC Envoy XUV, Buick Rainier CXL/CXL Plus, Oldsmobile Bravada, and Saab 9‑7x Linear models. Installation involves removing the existing check valve, aligning the flare connections, and securing with the factory‑specified torque. Ideal for both professional mechanics and DIY enthusiasts, the valve restores proper secondary air flow, helping the catalytic converter reach optimal temperature faster and reducing exhaust emissions during cold starts.
