Note: This is an aftermarket modification product.
Product Size & Heat Shield:
This is a cost-optimized aftermarket design. The compact size and absence of a heat shield are standard for this price segment, as reflected in the product images. It does not affect installation or functionality.
O2 Sensor Port Design:
The port features an internal small-hole design. This protects the sensor and improves durability. Initial codes may appear due to system sensitivity; this often resolves after using higher-grade fuel and driving normally for some time. The customer may also explore TDTAS decoding as an extended solution.
Summary:
The product meets aftermarket standards, is fully functional, and installs correctly. Our design balances cost, durability, and performance.
