Vararam Hemi Power Chamber Chevrolet Trailblazer 05-07



Model #VRX-H1

Shopper Award

By tilting the throttlebody downward to a specific angle of attack (Our secret), this allows the lower pathway to open up to its near 100% full volume. WE spent many hours fine tuning this angle in order to get the proper throttle response and velocity.

We also designed a balance plenum inside the bore. This allows the manifold vacuum to pull across the total neck area in a more uniform fashion. This action reduces unwanted pressure drop, and increases air flow volume.

We re-aligned the bore to help balance vacuum which increases flow velocity. (The stock bore is egg shaped)

In the rear of the Power Wedge we have integrated a variable radius air horn to boost the airs velocity just before it enters the body of the intake manifold plenum. Pushing flow and power even higher.

We kept the Power Wedge to a minimal thickness allowing for proper idle pulley clearance on all OEM applications. This will vary from engine to engine - LS-3 vs LS-2.

Construction- CNC machined from solid Zytel plastic, the same material most OEM intake manifolds are made from. This ensures that there is little to no added heat soak and that you will have a part that will last the lifetime of the engine.


  • Installation time is about 5-10min and uses your existing OEM bolts.
  • Increases airflow by as much as 10% on some applications
  • From Idle to max RPM, increases power and Torque across the entire curve

What is Vararam Industries?

Vararam Industries is well-known for manufacturing the finest ram air systems for your performance vehicle. Extensive testing and development go into every performance part that Vararam produces. The company delivers on its performance claims by building induction products, like ram air and cold air systems, that improve airflow to increase horsepower and torque figures. Vararam Industries builds products for Dodge Hemi engines, as well as the Chevrolet Silverado, Corvette, Camaro, Pontiac G8, and more! Vararam’s powerful systems feature the latest in aerodynamic technology to eliminate air restrictions and improve your car’s performance. Each individual component and system is built, tuned, and tested for specific applications without taking any shortcuts. 

Why Choose Vararam Industries?

Vararam Industries was created to bring true racing technology to the street by offering more real-world performance than any other intake system on the market. Compared to other systems out there, Vararam’s comes out on top every time. Its intake systems let your car’s engine breathe more freely with as little restriction as possible to deliver performance gains of up to 20 horsepower. Vararam uses a very tedious yet rigorous testing process of evaluating restrictions and reducing them to zero. The team then force-feeds the engine or tunes the system to particular applications to maximize the overall performance of that vehicle. Vararam’s priority is to make torque and power under the curve, rather than just peak power.
