Halltech Systems Hornet-518 Cold Air Intake - S&B Blue Dry Filter - NOMEX Sleeve (2020 - 2026 Chevrolet Corvette C8 Stingray / 2024 - 2026 E-Ray - Coupe / HTC) - HRNT.518
Give the LT2 in your C8 Corvette a purpose-built airflow upgrade with the Halltech Systems Hornet-518 Cold Air Intake. Engineered for 2020-2026 Corvette Stingray and 2024-2026 Corvette E-Ray models, the HRNT.518 combines a massive filter, application-specific airbox, molded-in velocity stack, and engineered MAF airflow management in a direct cold air intake replacement that Halltech states requires 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 specific configuration includes the S&B Blue Dry Filter and NOMEX insulating sleeve.
The Hornet-518 is engineered as a complete intake system rather than simply swapping the factory filter for a larger element. Its oversized filter provides more than 600 square inches of filtration area, while Halltech's molded-in velocity stack and reverse-flow partition are designed to maintain laminar airflow at the MAF sensor. The filter box is constructed from military-grade XLPE, and a stainless steel backplate retains the factory locations for the harness fasteners and antenna. The system also reuses the factory throttle-body connector hose, PCV fitting, left and right inlet ducts, and mounting bolts.

S&B Blue Dry Filter
This HRNT.518 configuration comes specifically with Halltech's S&B Blue Dry Filter. Halltech offers four filter choices for the Hornet-518, including both dry and oiled media. The blue S&B version gives C8 owners a dry-filter option while retaining the massive filter dimensions and more than 600 square inches of filtration area engineered into the Hornet-518 system.
NOMEX Insulating Sleeve
This version includes the NOMEX insulating sleeve in addition to the S&B Blue Dry Filter. It is the correct HRNT.518 configuration for owners who want Halltech's dry S&B filter option paired with the additional insulating sleeve rather than the otherwise equivalent no-sleeve configuration.
Engineered Airflow at the MAF Sensor
The Hornet-518 is designed around airflow quality as well as airflow capacity. Halltech incorporates a molded-in velocity stack and reverse-flow partition specifically designed to maintain laminar airflow at the MAF sensor. That controlled airflow allows the HRNT.518 to deliver its performance-oriented intake design while Halltech specifies that no ECU tuning is required.
More Than 600 Square Inches of Filtration
The Hornet-518's oversized filter provides more than 600 square inches of filtration area. Halltech pairs that substantial filter surface with its velocity stack, reverse-flow partition, and application-specific filter box to create a complete airflow system for the LT2 rather than relying on filter size alone.
Coupe and HTC Compatibility
Halltech engineered the Hornet-518 for both Coupe and HTC versions of the C8 Stingray and E-Ray. For HTC installation, Halltech specifies that the top-center rivnut on the access panel must be drilled out. The system otherwise functions as a direct cold air intake replacement while reusing multiple factory components and mounting locations.
