Since Stillen released its TruPower Cold Air Scoop for the Silverado, and Sierra, in 2019, the question never stopped: when is the full cold air intake coming? The answer is now. What took so long was not indifference. It was doing the job the right way.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EMore Than Just an Airbox and a Tube\u003C\/strong\u003E\u003Cbr\u003EBefore a single prototype was cut, the Stillen team set out to understand the factory system from the ground up. The first clue had already surfaced during scoop development, when opening the front inlet grille area gained nearly 10 horsepower on the dyno. If the front end was that choked, the rest of the system almost certainly was too. The factory intake channels air through the front core support, which is a good concept, but puts a hard ceiling on total airflow volume. Once it saturates, there is nowhere else for the engine to pull from.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EFollowing the Temperature Data\u003C\/strong\u003E\u003Cbr\u003ERather than guess, Stillen instrumented the engine bay with temperature sensors and mapped thermal conditions across the entire space. More airflow from the wrong location means hotter air, larger molecules, and a less efficient burn. The net power gain can be deceptively small. What the data revealed was a consistent low-temperature zone behind the headlight, inside an opening in the frame rails. Protected from engine heat by the wheel liner, this location pulls naturally ventilated air from outside the engine bay and became the foundation of the entire airbox design.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EClearing Out the Turbulence\u003C\/strong\u003E\u003Cbr\u003EThe factory intake tube is loaded with resonators, baffles, and muffler chambers engineered for mass-market refinement. Those chambers slow the air, create turbulence, and force the charge to work harder before it ever reaches the throttle body. Stillen eliminated all of it. The replacement tube runs a straight, smooth path from airbox to engine, maximizing velocity and minimizing restriction.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EThe Filter as a Sealing System\u003C\/strong\u003E\u003Cbr\u003EThe Stillen filter incorporates a secondary flange that extends past the filter media and interfaces directly with the airbox housing, creating a fully sealed joint at both the tube connection and the box. Every molecule of intake air goes through the element. None of it bypasses.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EWhat It Means Behind the Wheel\u003C\/strong\u003E\u003Cbr\u003ETwo years of development and real-world beta testing produced results that speak for themselves. The intake alone delivered 15 WHP and 12 lb-ft of torque on the dyno. Paired with the Stillen TruPower Cold Air Scoop, those numbers swelled to 24 WHP and 21 lb-ft at the rear wheels. Exceptional figures for a naturally aspirated V8. As a bonus, beta testers also often reported 1-2 MPG gains in real-world driving.\u003C\/p\u003E\u003Cp\u003EProof that when the engine breathes better, everything downstream improves: response off the pedal, engine efficiency, power under load, and consistency that holds up whether you are towing, hauling, or just running hard.\u003Cbr\u003E\u003Cstrong\u003EFeatures and Benefits:\u003C\/strong\u003E\u003C\/p\u003E\u003Cul\u003E\u003Cli\u003ETruPower Cold Air Intake w\/ Dry Filter 19-Present Chevrolet Silverado\/GMC Sierra 6.2L\u003C\/li\u003E\u003Cli\u003EProven Power and Torque Gains - 15 WHP and 12 lb-ft of torque on the intake alone.
