Direct-injected \u003cstrong\u003eDuratec 20\u003c\/strong\u003e engines frequently wash down unburnt hydrocarbons during short-trip combustion cycles, causing ceramic substrate washcoat degradation, cell meltdown, and premature catalytic failure. Over time, restricted internal matrix cell flow induces excessive exhaust backpressure, robbing engine output and triggering persistent check engine lights.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct-replacement unit features a heavy-gauge \u003cstrong\u003estainless steel\u003c\/strong\u003e tubular housing welded to precision-machined, direct-fit mounting flanges. Inside, an advanced flow-through \u003cstrong\u003eceramic substrate\u003c\/strong\u003e is treated with high-grade precious metal washcoats to maximize gas-phase conversion efficiency without choking exhaust flow. Integrated primary and secondary oxygen sensor bungs allow factory sensors to seat cleanly, ensuring correct air-fuel feedback to the powertrain control module.
