GR19 welcomes you to the 19th International Conference on General Relativity and Gravitation (GR19) to be held in Mexico City, from 5-9 July 2010.


Subject Matter

The subject matter of the conference is all areas of General Relativity and Gravitation, including Classical Relativity, Relativistic Astrophysics and Cosmology, Experimental Gravity, and Quantum Issues in Gravitation. The scientific program will be supervised by the Scientific Organizing Committee. A comprehensive social program has been planned for delegates, accompanying persons and families, offering a diverse range of activities to suit all tastes. Events include a welcome reception at the National Museum of Anthropology, a Mexican evening, and different city tours.

Technology Behind Cold Air Intakes

Your car's engine uses incoming air to mix oxygen with fuel to aid in combustion through the air intake system. The fuel needs the oxygen to burn and without that ignition, the engine won't operate. A cold air intake is an aftermarket replacement part that cools the temperature of the air entering the engine to give it more power. As air gets colder, it gets denser. When a gas heats up, the molecules spread further apart. A cooler gas has its molecules closer together. So, in terms of volume, colder air has more molecules, including oxygen, per square inch of space. And, the more oxygen your engine receives, the higher the engine output.

Cold air intakes are made to work with each specific type of car, so it's important to buy the one designed for your manufacturer, model and year of vehicle. Parts Geek offers over 10 million discount auto parts online, including the cold air intake for your car. The installation process can vary depending on the model and year of your vehicle, but it generally only requires few hand tools and no more than an hour of installation time. Installing one can add up 18 more horsepower and 40 more pounds of torque to your engine's operation. You can get up to one or two more miles per gallon on your fuel usage, too. You can easily make up the cost of buying and installing one at the fuel pump with your gas savings.

How to Install a Cold Air Intake System in my Car

Installing a cold air intake system in a vehicle isn't among the most mechanically difficult modifications to perform. As with any job, it's best to ensure all needed tools are on hand before taking anything apart. Many intake system replacements require, at least, a socket wrench set, screwdriver and pliers to complete the job. A replacement cold air intake system will also be needed on hand. Many different types of cold air intake systems are available from internet companies like Parts Geek.

Once tools and parts are secure, it is important to ensure the vehicle being modified is parked on a level surface with the parking brake engaged. Once the engine is cool to the touch, disengage the negative terminal to the battery. In order to get the old air intake system out, first remove vacuum hoses and air tubes connecting the air box to the throttle body. With the air intake tube disconnected, disconnect the mass air flow sensor if needed. From this point the stock box should be ready to separate from the engine bay.

Before putting the new cold air intake system in place, place a new, oiled air filter at the end of the intake pipe. These air filters can also be purchased from Parts Geek with a 30-day money back guarantee. Installing the new air intake system is then a matter of matching up hoses and tubes while closing off extra holes. These instructions are generally detailed in the manufacturer's manual.
