Land Rover is a British auto manufacturer that focuses primarily on luxury sport utility vehicles (SUVs). One of their product lines is the Land Rover Discovery, which is currently in its fourth production generation. Discoveries produced from 2004 to 2009 represented the third generation of the Discovery and are commonly referred to as LR3s. There were several engine offerings in the Land Rover LR3, ranging from a 2.7-liter V6 to a 4.4L V8. All versions of the LR3 have a healthy aftermarket community and can be made more powerful via the installation of high-performance aftermarket parts.
Replace the factory cold air intake system with a performance aftermarket cold air intake system. The cold air intake system takes in air, cooling the air and routing it into the engine itself. Factory cold air intake systems are somewhat restrictive to minimize engine noise. High-performance aftermarket cold air intake systems take in more air and cool it more efficiently, which increases horsepower and torque. They are also inexpensive and can be installed without professional assistance.
Replace the factory exhaust system with a performance aftermarket exhaust system. The exhaust system, in part, directs hot air out of the engine bay to maintain optimal operating temperatures. Factory exhaust systems limit airflow to minimize exhaust noise and CO2 emissions. High-performance aftermarket exhaust systems increase horsepower and torque by allowing hot air to exit the engine more freely. Aftermarket exhaust systems typically require professional installation and have the side effect of increasing exhaust noise and CO2 emissions. Check with state regulations before installing an aftermarket system on your Land Rover.
Mount a forced-air induction kit onto the LR3 engine. Forced-air induction kits come in two varieties: supercharger kits and turbocharger kits. Both types force large amounts of air into the engine when the driver depresses the gas pedal, which provides a big power boost. Forced-air induction kits can be extremely expensive, depending on the kit, and nearly always require professional installation. They also boost power so sharply that it may be necessary to upgrade other components of your LR3, such as the brakes, tires and suspension, to accommodate for the power increase.
