I recently bought a BMW 320i (55 plate) and somebody told me that I could listen to my mp3 through the car’s speakers. I’ve found a sort of plug socket in the middle glove compartment that looks as if it should be a connection but theres no way of connecting it to my mp3. Is there some sort of attatchment I need to buy, or is there some other problem?

The internal combustion engine of your Pontiac needs gasoline and air in order to make a complete combustion. Gasoline is basically made up of 2 elements?carbon and hydrogen; while air is made up of nitrogen and oxygen. The normal combustion process of your engine would produce nitrogen, carbon dioxide, and water vapor. These 3 by-products are the most desirable products of combustion. But unfortunately, gasoline engines do not run efficiently at all times. As a result, unburned hydrocarbons, carbon monoxide and nitrogen oxides are being produced. These ?terrible trio? of automotive pollutants are harmful to your engine components. Not only that, excessive amounts of these exhaust gases can contribute to urban air pollution and respiratory and heart diseases as well. To address this need, you car has been equipped with a group of components collectively known as the Pontiac exhaust system. These car components basically convey burnt gases from your engine through the subcomponents comprising it.

There are 3 types of exhaust systems?the header back, turbo-back, and cat-back. Header back comprises those exhaust system components starting from the header outlet to the final vent. This type of exhaust system is used in cars that are not equipped with turbochargers. On the other hand, turbo-back exhaust systems are used in cars that are equipped with turbochargers. It runs from the turbo charger outlet to the final vent to open air. Lastly, cat-back exhaust systems start from the outlet of the catalytic converter and ends to the final vent to open air. No matter what type of exhaust system you may have, it will make you benefit in three ways. First, you will get serious torque gains and horsepower. Second, you will get an improved fuel economy. And finally, you will get a growling and distinctive exhaust tone. The Pontiac exhaust system comes into action after your engine generates the exhaust gases in the piston chamber. These exhaust gases are exhaled out of the engine by traveling through various pipes and hoses and eventually at the back of your vehicle. A reliable Pontiac exhaust system conveys exhaust gases as fast as possible so your engine can breathe easier.

A typical anatomy of your Pontiac exhaust system comprises the exhaust manifold, headers, head pipe, catalytic converter, muffler, and tailpipe. You can usually see the exhaust manifold and headers directly above the engine cylinders. They are the starting blocks of your exhaust flow. The head pipe connects the exhaust manifold to the mufflers. The catalytic converter, on the other hand, converts harmful emissions such as nitrogen oxides, carbon monoxides and unburned hydrocarbons into less harmful gases. The muffler looks like a catalytic converter, but they serve the function of reducing exhaust noises. Finally, the tailpipe is the last piping of your exhaust system. Depending on the type of driving, regional climate, and maintenance, your Pontiac exhaust system is projected to last for 2 to 3 years. Among the major causes of exhaust system failure is internal corrosion, which can be attributed to acid moisture from the combustion process. Do not think twice on replacing your stock exhaust system with a new one if it gets worn out to maintain an efficient engine performance.

For years, vehicle manufacturers have been looking for means to make their products more at peace with the environment. These companies would actually go with innovating fuel-efficient vehicles that are more earth-friendly. One of the harmful elements coming from vehicles is the noxious emission, which is believed to be a big factor for global warming. Thanks to technology, there is a way to lessen or even avoid polluting the air, that is with the help of a catalytic converter, which is made out of high-quality metal that even Zinc cannot efface.

Saturn, is up for the challenge of a cleaner emission through the Saturn Catalytic Converter. Minimizing the Nitrogen Oxide coming out from the vehicle to Nitrogen and Oxygen and oxidizing Carbon Monoxide to Carbon Dioxide are the primary responsibilities of the Saturn Catalytic Converter. Moreover, the catalytic converter also oxidizes the unused hydrocarbons to Carbon Oxide and water. Through these procedures, Saturn users can expect a cleaner emission.

Like Saturn, protecting the environment is just as important as protecting passengers for Subaru. The Subaru Catalytic Converter is ready to safe-guard the environment by filtering the emission of the vehicle. Subaru has The Partial Zero Emissions Vehicle (PZEV) certification which is possible with the aide of the Subaru Catalytic Converter. By filtering the polluted emission, Subaru users have a 90 percent cleaner output.

Keeping the catalytic converters up and running should also be taken into consideration. Vehicles with these environment-friendly catalytic converters should only use lead-free fuel. These helpful auto parts may have varying results depending on the maker. The Saturn Catalytic Converter and Subaru Catalytic Converter may be carrying different brands, but their end goal is still the same anyhow—safeguarding the natural environment to which their customers will surely appreciate.

Camshaft tuning is an essential part of supercharger tuning. Camshafts orchestrate the valve opening and closing events in the engine and decide whether what comes out of our motor is beautiful high power music, or a mess of dysphonics.

The use of the proper supercharger optimized cam shaft can go a long way towards
