2021 Chevrolet Silverado 2500 HD Performance and Racing Products

This Momentum GT intake system produces 20hp, 23lbs x ft of torque, and outflows the factory intake by 38%. The one-piece sealed housing includes auxiliary air inlet to eliminate the use of multiple-piece housings and ensure the coolest air intake charge available. A large, clear sight window is used for a hassle-free filter inspection and an aggressive style. A urethane plug is also included if you wish to block off the auxiliary air inlet. This system uses a high quality, dyno-tuned intake tube to achieve maximum power gains while maintaining a perfect fit. A custom high temperature reinforced silicone elbow coupling with aluminum fitting is included for easy install to the factory breather line.

Product Features:

• Increased HP/Throttle Response
• Patented Housing To Filter Interface
• Includes Pro 5R Air Filter
• Uses Factory Mounting Locations

The K&N 57-3034 FIPK air intake system replaces your vehicle’s restrictive factory air filter and air intake housing. K&N air intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engine’s RPM range. The 57-3034 air intake comes with a K&N high-flow air filter and a heat shield that installs into the previous air box space. Air is directed through an aerodynamically engineered intake tube into the engine’s throttle body for a guaranteed power gain. The air intake system accommodates the factory mass air sensor and filter restriction gauge. The oversized round tapered air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install usually in 90 minutes or less using the existing factory mounting points. The tools needed are a screwdriver, a ratchet set and several wrenches.

Product Features:

• GUARANTEED INCREASE IN HORSEPOWER: Dyno-tested with up to 50% more airflow than restrictive factory box air filter and intake tube
• BETTER TOWING: Improves acceleration and uphill performance when towing by improving throttle response.
• IMPROVED ENGINE SOUND: Hear the power under the hood.
• WORLD CLASS PROTECTION: Pushing the limits of engine protection by protecting your engine from harmful contaminants
• EASY MAINTENANCE: No filter cleaning required for up to 100,000 miles
• EASY TO INSTALL: Bolt-on power in less than an hour with basic hand tools. K&N air intake systems are one of the easiest ways to guarantee an increase in horsepower.
• DYNO TESTED: Dyno-tested for a guaranteed increase in horsepower and acceleration with no ECU tune required
• HIGH QUALITY: Made in America.

The K&N 77-3077KP high-flow performance air intake system is a free-flowing, mandrel-bent aluminum tube air induction system designed to fit some GMC Sierra 2500/3500 HD and Chevrolet Silverado 2500/3500HD models. The restrictive factory air filter and air intake housing on your vehicle are replaced by this K&N air intake system which is designed to dramatically reduce air flow restriction as it smoothes and straightens air flow. The improved air flow allows your engine to inhale a larger amount of air than it would from the stock air intake. More air means more usable power and acceleration throughout your engine’s RPM range. The 77-3077KP air intake comes with a black rubber topped K&N high-flow air filter and a heat shield that installs into the previous air box space. Air is directed through the intake tube into the engine’s turbo inlet for a guaranteed power gain. The intake tube has an attractive chrome-like finish that’s made to last and it accommodates the factory mass air sensors. The oversized cone shaped air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install usually in 90 minutes or less using existing factory mounting points. The tools needed are a screwdriver, ratchet set and some Allen wrenches. Some K&N 77 series air intakes are not legal for sale or use in California and other states adopting California emission standards while others are CARB exempt and 50 state legal. Check the K&N catalog or website for vehicle applications and specific CARB status for each vehicle and air intake.
