K&N 63 Series High Performance Intake
All new from K&N is another high performance intake system specifically designed for the all new Shelby GT500!!

The Shelby GT500 boasts a power packed 500hp from the factory but there's still more power to be made. From the factory the Shelby comes with a very restrictve intake system. This keeps the supercharger and engine from getting the cold air charge which creates more power. The all new K&N 63 Series intake takes care of that problem with it's new 63-2571 intake system. Made from injection molded plastic and K&N's pattented filter design you'll give your Shelby the charge of cool air it needs. Expect to see gains of almost 50 hp with this kit The K&N intake not only creates more power but is also a simple product to install. The air kit comes with all the necessary pieces for a simple bolt on application which can be done in less than 20 minutes.

Metco 2007+ Shelby GT500 Interchangeable Supercharger Pulley

Metco Motorsports Interchangeable Supercharger pulleys for your all new GT500..How it works is the smaller diameter of this pulley allows the supercharger's rpm's to increase. This in turn allows the supercharger to flow more air and create more boost pressure which makes power. The Metco pulley design uses a hub and ring style setup. This means you press the hub onto the superchargers shaft and then bolt the pulley ring to it with allen bolts. The hub and ring design allows for quicker pulley changes which can be done in less than 5 minutes.

The Metco GT500 Supercharger Pulleys are offered in a 2.60" and 2.80" size to add more boost and simply gain more HP and TQ across the board..

Typical Boost gains:
2.60" adds 4lbs of boost
2.80" adds 2lbs of boost

Lethal Performance is proud to offer the Metco Auxiliary Idler Assembly. The Auxiliary Idler kit is designed to provide maximum belt contact of the supercharger pulley, thereby decreasing the amount of belt slippage in high boost situations.

NGK TR6 Spark Plugs- These are a must when upping the boost with a smaller supercharger pulley. The more boost you make the hotter the intake temperatures get. The TR6 spark plug is 1 heat range colder than the GT500 spark plug. This helps to cool the intake charge in the combustion chamber which helps to prevent detonation. The ideal spark plug gap for the GT500 running either the 2.60" or the 2.80" pulley is .035.
