What really matters nowadays is also how far the car engine can reduce the emission of exhaust gases and it is the reason why catalytic converters are now compulsory in exhaust system of every car. BMW catalytic converter is used to convert those harmful gases like carbon monoxide, nitrogen oxides and hydrocarbons into less harmful gases like carbon dioxide and nitrogen plus water. Also the engine performance is of the same importance and is required to burn the air-fuel mixture completely. But due different load and speed conditions such ideal combustion is hardly achieved and leaves out residues or unburnt fuel at the exhaust.
The catalytic converter however burns this partially burnt fuel mixture before it escapes through the tail pipe. This crucial process is done easily by the catalyst present inside the converter. Catalyst is a substance that takes part in the chemical reactions but it itself remains unchanged. Because of high temperatures at the exhaust side, these converters gets damaged however they are designed perform for a sufficient period of 10 years. But uncertainties reduce their life expectancy. Avoid purchasing those expensive OEM converters for your BMW instead try the catalytic converters from world class brands like Eastern, Bosal or Walker with same specifications and durability like your original ones with very less price to pay.Looking to buy catalytic converters log on to http://www.theautopartsshop.com/auto+car-usa+parts/bmw+z8+catalytic-converter.html to place a quick order with free shipping and warranty.
