Halltech Systems Hornet-518 Cold Air Intake - S&B Blue Dry Filter - No NOMEX Sleeve (2020 - 2026 Chevrolet Corvette C8 Stingray / 2024 - 2026 E-Ray - Coupe / HTC) - HRNT.518
Uncork the LT2 with a cold air intake engineered specifically around the airflow demands and packaging of the C8 Corvette. The Halltech Systems Hornet-518 Cold Air Intake replaces the factory intake with a high-flow design featuring an enormous filter, engineered MAF airflow management, and a purpose-built airbox while requiring no tuning. Halltech's Stingray dyno testing recorded gains of more than 17 horsepower and 25 torque, although Halltech notes that results have varied. This HRNT.518 configuration includes the S&B Blue Dry Filter and does not include the optional insulating sleeve.
The Hornet-518 goes beyond simply putting a larger filter behind the LT2. Halltech incorporates a molded-in velocity stack and reverse-flow partition designed to maintain laminar airflow at the MAF sensor. The oversized filter provides more than 600 square inches of filtration area, while the filter box is constructed from military-grade XLPE. A stainless steel backplate keeps the factory harness fasteners and antenna in their original locations. The system also reuses the factory throttle-body connector hose, PCV fitting, left and right inlet ducts, and mounting bolts for an installation that retains key factory components.

S&B Blue Dry Filter
This HRNT.518 is configured with Halltech's S&B Blue Dry Filter option. The dry-media design is ideal for C8 owners who prefer a filter that does not require filter oil while retaining the massive filtration area engineered into the Hornet-518. Halltech offers both dry and oiled filter choices for this intake, so this version is specifically for buyers who want the S&B dry-media configuration.
Engineered Airflow at the MAF Sensor
More airflow only helps when the engine management system receives a stable, usable airflow signal. Halltech addresses that with a molded-in velocity stack and reverse-flow partition designed to provide laminar airflow at the MAF sensor. Combined with the Hornet-518's oversized filter and application-specific airbox, the design gives the LT2 a performance-oriented intake system without requiring ECU tuning.
More Than 600 Square Inches of Filtration
The Hornet-518 uses a massive filter with more than 600 square inches of filtration area. That large surface area is a fundamental part of Halltech's intake design, providing the LT2 with a substantial filter through which to draw air rather than relying on a small filter element as airflow demand increases.
No NOMEX Sleeve Configuration
This specific HRNT.518 configuration does not include the optional NOMEX insulating sleeve. It includes the Hornet-518 intake with the S&B Blue Dry Filter while leaving out the additional intake-tube sleeve. This makes the configuration clear for buyers comparing the different HRNT.518 filter and sleeve combinations.
Coupe and HTC Compatibility
Halltech engineered the Hornet-518 for both Coupe and HTC versions of the C8 Stingray and E-Ray. Halltech specifies that the HTC installation requires the top-center rivnut on the access panel to be drilled out. The intake otherwise retains the factory mounting arrangement and reuses multiple factory intake components.
