🛠️ Simplified Installation Steps
Remove cold air intake, engine cover (reinstall oil cap to avoid contamination), engine cover bracket, oxygen sensor, and heat shield.
Inspect exhaust manifold for cracks (replace if damaged—cracks cause non-warrantable converter failure!); save intake flange nuts.
Remove engine support bracket and old converter. Align the new converter and loosely secure with one top nut.
Attach engine bracket to the new converter hanger (critical for long-term durability!). Reinstall downstream oxygen sensor.
Tighten inlet/outlet flange nuts and bolts to manufacturer’s torque specs.
Reinstall heat shield, oxygen sensor, support bracket, engine cover, and cold air intake.
⚠️ Important Tips
Converters rarely fail alone! Before replacement, inspect your exhaust system (cracked manifolds, leaks) to fix the root cause of check engine lights—this ensures long-term performance.
Double-check the OE number and product images to confirm compatibility. Unsure? Send us a message—we’ll help you verify!
Professional installation is highly recommended (no instruction manual included).
