Buick Enclave Catalytic Converter

The Catalytic Converter is one of the major parts of the exhaust and emission systems fitted in Buick Enclave vehicles to minimise toxic compounds emitted during combustion. CO and HC, as well as NOx, are primarily altered into water, CO2, and N2 by means of chemical reactions that are catalysed by platinum, palladium, and rhodium. Catalytic converters used in Buick Enclave models of the years have included two way and three way converters with designs for efficient function. The latter became standard by 1981 making further improvements on the reductions of NOx emissions. There also exists the high flow types intended for achieving better performance while at the same time meeting the required levels of catalytic conversion. These converters can either be direct fit converters, which means that they will require no additional modification and can be bolted in place; or they are universal converters, which can with need minor alteration to be installed.

Each OEM Buick Enclave Catalytic Converter we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
