The Negative Pressure Sensor monitors the vacuum level in the intake system, providing critical data to the ECU. In the C7 Intake System, it helps detect air filter clogging and ensures optimal engine performance.
These self-tapping screws are used to secure sensor brackets and small covers in the C7 Intake System. The cross recess head allows for easy installation with standard screwdrivers, and the zinc-plated finish resists corrosion.
This robust bracket assembly supports the air filter housing and secures it to the chassis. In the C7 Intake System, it is fabricated from heavy-gauge steel with a powder-coated finish, providing a durable and stable mounting platform.
These heavy-duty M14 serrated flange bolts secure the main intake brackets to the chassis. The serrated flange provides a positive lock against loosening, making them ideal for high-vibration areas of the C7 Intake System.
This pre-formed steel pipe carries filtered air from the air filter to the turbocharger. In the C7 Intake System, it is made of corrosion-resistant steel with a smooth internal bore, minimizing flow restriction and ensuring maximum airflow.
This flexible air hose connects the intake pipe to the air filter housing. Manufactured from reinforced rubber, it is compatible with China III emission standards and provides a durable, leak-free connection in the C7 Intake System.
These stainless steel hose clamps secure the air hoses to their respective connectors. In the C7 Intake System, they provide consistent clamping force and are resistant to corrosion, ensuring leak-free connections throughout the system.
The Lower Intake Duct Assembly routes air from the filter to the turbocharger. Manufactured from impact-resistant plastic, it is designed to withstand the harsh under-hood environment of the C7 Intake System.
This adhesive-backed sealing strip is used to seal gaps between the intake duct and the body panels. In the C7 Intake System, it prevents unfiltered air from entering the engine bay and reduces noise.
This curved metal strip secures the sealing strip to the intake duct. In the C7 Intake System, it ensures a tight seal and prevents the sealing strip from peeling off over time.
This large-diameter clamp secures the main air hose connection. With a range of 240-260mm and a 12mm band width, it provides a secure hold on large-diameter hoses in the C7 Intake System.
These M6 flange bolts secure smaller brackets and sensors in the C7 Intake System. Made from grade 8.8 steel with a zinc plating, they provide reliable fastening for light-duty components.
These oversized washers are used under bolt heads to distribute load and protect the surface of plastic components. In the C7 Intake System, they prevent cracking and ensure even clamping pressure.
This bracket supports the intake connection pipe and ensures it remains properly routed. In the C7 Intake System, it is made of steel with a corrosion-resistant coating, providing a secure mounting point.
This additional bracket assembly provides support for the intake ducting. In the C7 Intake System, it is designed to absorb vibration and prevent stress on the intake components.
The Upper Intake Bellows is a flexible corrugated hose that connects the air filter to the intake duct. In the C7 Intake System, it accommodates engine movement and thermal expansion while maintaining a leak-free seal.
This main intake duct routes air from the grille to the air filter housing. Manufactured from impact-resistant plastic, it is designed for the L40/41 chassis without a cyclone pre-filter, offering a direct air path in the C7 Intake System.
The Trim Panel Assembly provides a finished appearance to the intake system and protects the ducting from damage. In the C7 Intake System, it is made of durable plastic with a textured finish, matching the vehicle’s interior.
This spacer bushing is used to maintain correct alignment between the intake components. In the C7 Intake System, it is made of steel with a corrosion-resistant coating and ensures proper spacing for mounting.
This button head screw is used for securing trim panels and covers. In the C7 Intake System, it provides a low-profile fastening solution that does not interfere with adjacent components.
This longer button head screw is used for deeper mounting points. In the C7 Intake System, it provides secure fastening for larger brackets and components.
These rubber-metal cushions isolate the intake system from chassis vibrations. In the C7 Intake System, they reduce noise transmission and protect the ducting from fatigue damage.
These threaded inserts provide strong fastening points in thin sheet metal. In the C7 Intake System, they are used to attach brackets and components without the need for welding.
These bushings provide a bearing surface for pivoting components in the C7 Intake System. Made from wear-resistant material, they ensure smooth operation and long service life.
These standard hexagon nuts are used with bolts throughout the C7 Intake System. Manufactured from zinc-plated steel, they provide reliable clamping force and corrosion resistance.
This rubber strip with adhesive backing is used to seal gaps and prevent chafing. In the C7 Intake System, it protects the ducting from sharp edges and reduces noise.
These M10 serrated flange bolts secure the main intake brackets. The serrated flange provides a positive lock against loosening, making them ideal for high-vibration areas of the C7 Intake System.
The C7 Intake System uses a high-efficiency flame-retardant filter element that captures particles down to 5 microns, protecting the engine from wear and extending service intervals.
This C7 Intake System kit includes every filter, duct, hose, clamp, sensor, bracket, and fastener needed for a full installation. The all-in-one solution saves time and ensures compatibility.
