TPIS 90mm Throttle Body

For the biggest cubic inch motors, 90mm billet flows a whopping 1500 cfm. That�s a 69% increase in CFM over the stock throttle body. The front has been resized to accept the stock air duct and the bolt pattern will fit both the F.A.S.T. LSX and the stock LS2 intakes.

The F-Body 90mm is sold without the I.A.C. and T.P.S. and the Vette 90mm is sold without the fly by wire motor and idler gear. If you are installing on a car originally equipped with these parts, then these parts will transfer to the 90mm. If you are installing in a special application, you will need to purchase these parts.

C6-C5 Blackwing air filter
These filters contain a unique synthetic filter media. The fibers are extremely uniform and very small to trap tiny particles without restricting air flow. They flow more air and trap smaller particles than ordinary cotton gauze filters, even the so-called "high performance" types! They perform under the harshest possible conditions to protect expensive engines. GM has a world-class sports car in the C5, but the stock air filter assembly is VERY restrictive! This filter assembly brings your the highest flow system available for the C5. It incorporates 100% synthetic filtration media (synteq) developed by Donaldson, the world leader in OE filter technology. Included with this assembly is a unique FLOW INDICATOR. This gauge changes color to let you know when the filter need cleaning. Clean the filter and reset the indicator and you're ready to go. In laboratory testing, the Blackwing filter has boasted up to a 90% increase in airflow over the OEM filter with up to 18 additional horsepower over stock and as much as 5 additional horsepower over competitors. It's a simple bolt on installation that requires NO vehicle modifications. All necessary and complete instructions are included.

K&N Induction System
Its huge molded plastic tube has ample area to feed even the highest horsepower engines. And it relocates the filter to pick up cool, dense air from outside the hot engine compartment, resulting in 10 extra horsepower on a stock engine. Horsepower gains increase as an engine’s demand for air goes up. This system can be worth up to 25 horsepower on a modified engine.

Induction System

 

This K&N high flow, cold air induction system replaces the restrictive factory set up of the Camaro or Impala SS in about one hour and with only minor modifications.
