Everything you need to know before you sell
The 18150-14-6977 is an OEM catalytic converter used on the 2003–2006 Honda Ridgeline. It is classified as a Pre-Catalytic Converter and weighs approximately 13.1 lbs. Pre-catalytic converters (pre-cats) are small secondary converters positioned close to the engine manifold. They heat up quickly to reduce cold-start emissions and often contain concentrated rhodium loadings.
Like all catalytic converters, the 18150-14-6977 contains three platinum group metals (PGMs): platinum, palladium, and rhodium. These metals are embedded in the ceramic or metallic honeycomb substrate inside the converter shell. When the converter reaches the end of its service life, these metals can be recovered through a refining process and sold on the precious metals market.
Based on typical assay results for the 18150-14-6977 unit, this converter contains approximately 4.17 grams of platinum, 5.55 grams of palladium, and 1.41 grams of rhodium. At current spot prices (platinum $1,050/troy oz, palladium $1,020/troy oz, rhodium $4,800/troy oz) and a standard 72% recovery rate, the gross metal value works out to approximately $388.
The actual price offered by a recycler will depend on the condition of the converter, the current PGM market, and the recycler's processing costs.
