all the problems associated with faulty or leaking EGR (exhaust gas recirculation) systems. Power Pipe kits replace exhaust gas re-circulation (EGR) valve assembly, for improved performance, thermal efficiency, fuel consumption and smoke emission. Eliminates tar and sediment build up inside inlet manifold, which in turn reduces air flow. Improves thermal efficiency by reducing heat build up in the inlet manifold. The Power Pipe has no internal restrictions, unlike the old EGR valve assembly. All these advantages combine to give improvements in overall fuel consumption and performance with a reduction in exhaust smoke.
