Years ago you`d have found plenty of blokes tinkering with their cars on a Sunday morning. Bonnets throughout the land would have been open and men would have been furiously adjusting carburetors and setting the gaps in their spark plugs. Nowadays engines have become more advanced and cars in general have more intricate parts put on them. It`s highly fashionable for performance Car Parts to be fitted to cars these days especially by drivers of a certain age. These Car Parts vary and they can help to improve the overall performance of the car which is what the driver intends. Amongst the many items available in the performance Car Parts ranges are exhausts, brakes and air filters. When these items are fitted to a car the difference in the power can be quite amazing as can the car`s stopping abilities. Other performance Car Parts include tyres and wheel packages that can help to improve the look and handling of the car. Add-on features like spoilers and front splitters can give the car great street credibility and make it stand out from other cars of a similar make. Sundays these days usually find drivers meeting up at places like Mcdonalds to compare the Car Parts they have been fitted to the cars. It`s not like the old days when Morris Minors would sit in domestic garages whilst their owners tinkered with their engines.

Modern cars now have Catalytic Converters fitted to them to help reduce the emissions that are released through their exhaust systems. Part of the current MOT test stipulates that vehicles must pass an emissions test and any vehicle that fails the test will fail the MOT. Like any other car part, Catalytic Converters wear out in time and they have to be replaced. There`s no point trying to dodge the issue when the Catalytic Converters start to fail they have to be changed. Take your car to a main dealer to have the cat changed and they will almost certainly charge you a fortune. However, if you shop around great savings can be made and Catalytic Converters can be sourced at reduced prices. Shop online and you`ll discover there are automotive suppliers that can provide Catalytic Converters for any make of car. It doesn`t matter if your Mazda needs a catalytic convertor or your Minis just failed the emissions test because a new cat could soon be in place. Contact the automotive supplier of Catalytic Converters online and give them the details of the make of your car. They`ll be able to check their stock and provide you with a replacement that can easily be fitted to your motor.

The Exhausts that are fitted to cars help to remove waste gases from the engine. Standard types of Exhausts merely provide this function but other types of Exhausts can be fitted to improve the look, sound and power output of a car. Aftermarket Exhausts can be fitted to cars of all types and they will enhance the appeal of the vehicle greatly. Take your average Punto or Clio and fit them with performance Exhausts and just listen to the cars as they take off down the road. Certain types of Exhausts will give off a deep and throaty growl that sounds wonderful when the engine is revved. Numerous manufacturers make performance Exhausts and here in the UK there are automotive suppliers that can provide these Exhausts for any make of car. At the moment you might have a box standard Fiesta but are in the process of turning it into a hot ride. Plenty of performance parts and accessories are available for you to put on your car and when you want to improve the noise you can fit one of the sporty Exhausts. Not only will it remove waste gas from the engine it will give your car a glorious new soundtrack that it can take to the streets.

Brake Pads are an important part of braking systems for all types of vehicles that are equipped with disc brakes. Brake pads are steel backing plates with friction material bound to the surface facing the brake disk. Brake pads convert the kinetic energy of the car to thermal energy by friction. When a brake pad is heated up by coming into contact with either a drum or rotor, it starts to transfer small amounts of friction material to the disc or pad (that is the reason a brake disc has a dull grey). The brake rotor and disc (both now with friction material on), will then "stick" to each other to provide stopping power. The friction of the pad against the disk is however responsible for the majority of stopping power. In disc brake applications, there are usually two brake pads per disc rotor, held in place and actuated by a caliper affixed to a wheel hub or suspension upright. There are numerous types of brake pads, depending on the intended use of the vehicle, from very soft and aggressive (such as racing applications) and harder, more durable and less aggressive compounds. Most vehicle manufacturers recommend a specific compound of brake pad for their vehicle, but compounds can be changed (by either buying a different make of pad or upgrading to a performance pad in a manufacturer's range) according to personal tastes and driving styles. Care must always be taken when fitting non standard brake pads, as operating temperature ranges may vary, such as performance pads not braking efficiently when cold or standard pads fading under hard driving. In cars that suffer from excessive brake fade, the problem can be minimized, by installing better quality and more aggressive brake pads.

An Oxygen Sensor, or Lambda Sensor, is an electronic device that measures the proportion of Oxygen (O2) in the gas or liquid being analyzed. The original sensing element is made with a thimble-shaped zirconia ceramic coated on both the exhaust and reference sides with a thin layer of platinum and comes in both heated and unheated forms. Car Oxygen/Lambda Sensors, colloquially known as O2 Sensors, make modern electronic fuel injection and emission control possible. Oxygen/Lambda Sensors determine if the air fuel ratio exiting a gas-combustion engine is rich or lean. Closed-loop feedback-controlled fuel injection varies the fuel injector output according to real-time sensor data rather than operating with a predetermined fuel map. In addition to improving overall engine operation, Oxygen/Lambda Sensors reduce the amounts of both unburnt fuel and oxides of nitrogen from entering the atmosphere. Information on oxygen concentration is sent to the engine management computer or ECU, which adjusts the mixture to give the engine the best possible fuel economy and lowest possible exhaust emissions. Failure of these sensors, either through normal aging, the use of leaded fuels, or fuel contamination with silicones or silicates, for example, can lead to damage of a vehicle's catalytic converter and in turn incur expensive repairs. The Oxygen/Lambda Sensor is typically screwed into a threaded hole in the exhaust system, located after the branch manifold of the exhaust system combines, and before the catalytic converter. Normally, the lifetime of an unheated Oxygen/Lambda Sensor is about 30,000 to 50,000 miles. Heated Oxygen/Lambda Sensor lifetime is typically 100,000 miles. Failure of an unheated Oxygen/Lambda Sensor is usually caused by the buildup of soot on the ceramic element, which lengthens its response time and may cause total loss of ability to sense oxygen. For heated Oxygen/Lambda Sensors, normal deposits are burned off during operation and failure occurs due to catalyst depletion, similar to the reason a battery stops producing current. The Oxygen/Lambda Sensor then tends to report lean mixture, the ECU enriches the mixture, the exhaust gets rich with carbon monoxide and hydrocarbons, and the mileage worsens.
