Steeda Cold Air Intake Kit
Gain horsepower and torque with this straightforward and easy upgrade. Lifetime filter can be cleaned and re-oiled, but the big news here is that we've streamlined the airflow in the GT 500 Mustang to the point that a computer re-flash isn't just an option, it's required!
The kit is supplied with a stainless steel air box with built-in Billet aluminum Super Velocity stack. It mounts in the factory location with the supplied rubber trim to keep the hot air out. Billet mass air meter is bright nickel plated for a lustrous shine and measures in at an industry leading 114mms!! Our tests showed inlet temps a mere 5 degrees above ambient temperature. The Steeda Lifetime Filter can easily be cleaned and re-oiled, making maintenance a snap. All stainless steel hardware required for installation is included in the kit.
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. 2.60" adds 4lbs of boost.
In stock and ready to ship.
NOTE: When using either the 2.60" or the 2.80" pulley you can use your stock belt by using the Metco Auxiliary Idler Kit
DivisionX Shelby GT500 Auxiliary Idler Kit
Lethal Performance is proud to offer the DivisionX 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.FEATURES:
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.
