2005-2006 Pontiac GTO Vararam Cold Air System

Vararam set their design target to support 800 horsepower and up to 500 cubic inch engines turning at up to 7000 RPM, all while keeping the system easy to install and making it a "true" cold air system that breathes better when the hood is closed (versus open as on a dyno).

They accomplished this goal through intensive on-road and track testing which revealed the shortcomings of every other aftermarket system they tested from US and Australian manufacturers.

They all suffered from heat soak because the GTO has a sealed engine compartment. This allows very little air in or out, so these cars run hot in stock form and even hotter if the motor is built or supercharged.

They tested kits that used many configurations -- some went over the radiator, some to the fender, and others sealed to the hood -- all of them heat-soaked the mass air flow (MAF) meter and air box assembly.

This in turn caused the ECU to pull timing out of the motor and this also forces the tuner to detune for the street or track VS the dyno with the hood open and a fan blowing.

Vararam designs products for the real world and not for a dyno test only, because you don't win races with the car standing still on a dyno!

Vararam guarantees that you will get 3 tenths or 3 mph through the 1/4 mile and or 2 tenths or 2 mph above any other system on the market or they will take the system back and pay shipping both ways! How do they do this? Here's how:

• Step 1: Relocate the MAF meter in front of the throttle body which improves response and sensor accuracy
• Step 2: Place the MAF inside the air box with the filter to shield it from engine heat
• Step 3: Create a positive seal around the perimeter of the intake plenum chamber and force feed air in through the front grilles
• Step 4: Select the proper air filter to feed the engine and intake plenum with enough air for stock and modified heads resulting in air flow of 1350-1800 CFM (depending on filter choice) at SAE standard measurement factors
• Step 5: Trimming the radiator shroud to help deliver maximum air flow to the filter (also helps with hood clearance) - the key here is that without this slight trim work, air flow was reduced by 50%!
