Audi S4 Catalytic Converter

The Audi S4 Catalytic Converter creates the much needed combination of clean air and good performance by converting harmful gases while letting the performance engine breathe freely. Fitted on the greatly hot side of the exhaust, this Catalytic Converter consists of a platinum, palladium, and rhodium honeycomb that oxidizes carbon monoxide and hydrocarbons and reduces nitrogen oxides with no additional drag. The replacement of the previous ceramic beads with a monolithic substrate reduces pressure and consequently the Audi engine spools the turbos quicker and maintains firm throttle response. This unit alone fits directly to all S4 generation sedan, Avant, and Cabriolet layouts with the same flow and emissions control whether you are driving an old biturbo V6 or the modern 3.0-liter power plant. A proper Catalytic Converter also protects turbochargers as it prevents heat buildup and counter pressure, which wear bearings and reduce power. Rattles, a glowing check engine light, or slow pulls are warning signs that appear as soon as the catalyst is coated by deposits from misfires or fluid leaks that block an Audi exhaust path. Constructed with a robust stainless shell that brushes off road debris and temperature fluctuations, it has received long-term compliments in the circles of fanatics for reliability and minimal maintenance. The converter requires no regular maintenance; it only serves the S4 by passing inspections and retaining all factory horsepower, not to mention cabin air quality. There are few competitors that combine the minimum restriction and cleaning power of this Catalytic Converter in a small size that is the guardian ensuring an Audi runs clean, fast, and safe. By opting to put this high-tech exhaust component into an Audi, you will have the thrill of a sports car without polluting the planet or your nose.
