<p>The O2 cel fixture actually contains a miniature catalytic converter so if the real catalytic converter is damaged, the CEL eliminator can help you reduce toxic gasesthat helps to the annoying inspection of the engine light even if the high-flow catalytic converter is installed after modifying the exhaust gas or removing the catalytic converter.</p> <p>Don't risk using extensions because they usually don't work, this is a built-in real mini-catalytic converter.</p> <p>This O2 cel fixture with a miniature cat will make your ECU think the inventory catalytic converter is still installed. When you remove the catalytic converter, the rear O2 sensor will see higher temperatures and greater unburned fuel flow.</p> <p>Therefore, this will throw an inspection engine light (Cel, , DTC), usually with error code P0420 (catalyst system efficiency below threshold library 1) and \/ or P0430 P0420 - catalyst system efficiency below threshold library * for OFF ROAD It takes a long time to use.</p> <p>But sometimes, CEL alerts are caused by O2 sensor problems. For example, the O2 sensor is too sensitive and the CEL will still turn on after the canceller is loaded. It will still cause more code errors!</p> <p>So our CEL canceller (someone called Mini cat) can't solve all the problems on the CEL alert.</p> <p>It can only solve one of the P0420 codes - Fault Catalytic Converter (most common)</p> <p>1. Threads are made with special tools for perfect precision and repeatability.</p> <p>2. Simple structure, excellent material, not easy to deform or rust.</p> <p>3. Universal accessories for most vehicles with M18 * 15 O2 sensor holes.</p> <p>4. Made of high quality ,high strength and durable.</p> <p>5. Simple installation, direct fixing bolts, no need to modify.</p> <p>Condition: new</p> <p>Type: O2 Sensor Gasket Adapter</p> <p>Weight: 44 g</p> <p>Thread: M18 X 15</p> <p>Size:about 185 * 098 * 118 inches</p> <p>Material:metal</p> <p>colour:Silver</p> <p>Package Contents:</p> <p>1 * Oxygen Sensorapter</p> <p>Only the above package content, other products are not included.</p> <p>Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
