WebGPF costs. Based on an assessment of production costs for two GPF designs, we estimate for a 2.0L gasoline engine a cost of $106 for a stand-alone GPF and between $114 and $154 for a four-way catalyst, presented here as a three-way catalyst (TWC) with PM trapping capabilities. The true cost will depend on the choice of the system being WebNov 28, 2013 · A 4-way catalytic converter is an all-in-one catalyst and particulate filter. 4-way could give benefit regards EBP compared to series TWC + GPF, but is expected to come at a cost due to relative high PGM efficiency of a flow-through catalyst vs. wall flow filter. 4-way may be of interest to VMs with rigorous package, weight and performance ...
