Halltech Systems Hornet-518 Cold Air Intake - S&B Gray Oiled High-Flow TRACK Filter - NOMEX Sleeve (2020 - 2026 Chevrolet Corvette C8 Stingray / 2024 - 2026 E-Ray - Coupe / HTC) - HRNT.518
Turn up the airflow potential of your LT2-powered C8 with the Halltech Systems Hornet-518 Cold Air Intake. Engineered specifically for 2020-2026 Corvette Stingray and 2024-2026 Corvette E-Ray models, the HRNT.518 combines a massive filter, purpose-built 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, with Halltech noting that results have varied. This specific configuration pairs the S&B Gray Oiled High-Flow Track Filter with the NOMEX insulating sleeve.
The Hornet-518 is engineered as a complete airflow system instead of simply replacing the stock filter with a larger element. Its oversized filter provides more than 600 square inches of filtration area, while the molded-in velocity stack and reverse-flow partition are designed to maintain laminar airflow at the MAF sensor. Halltech builds the filter box from military-grade XLPE and uses a stainless steel backplate that 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 Gray Oiled High-Flow Track Filter
This HRNT.518 configuration uses Halltech's S&B Gray Oiled High-Flow Track Filter. Halltech offers four filter choices for the Hornet-518, including both dry and oiled options, and specifically identifies this gray S&B version as the High-Flow Track Filter. It is the track-oriented S&B filter choice for C8 owners who want an oiled filter while retaining the massive filtration area engineered into the Hornet-518.
NOMEX Sleeve Configuration
This version includes the NOMEX insulating sleeve along with the S&B Gray Oiled High-Flow Track Filter. That separates it from the otherwise equivalent no-sleeve configuration and makes it the correct HRNT.518 combination for buyers who want Halltech's high-flow track filter paired with the NOMEX sleeve.
More Than 600 Square Inches of Filtration
The Hornet-518 uses an oversized filter with more than 600 square inches of filtration area. Halltech combines that substantial filter surface with its purpose-built airbox and engineered airflow path, giving the LT2 a complete intake system designed around both airflow capacity and airflow quality.
Engineered MAF Airflow Without Required Tuning
Modern C8 engine management makes airflow quality at the MAF sensor just as important as total airflow capacity. Halltech addresses this with a molded-in velocity stack and reverse-flow partition designed to maintain laminar airflow at the MAF sensor. Halltech specifies that the HRNT.518 requires no tuning, allowing the Hornet-518 to deliver its performance-oriented airflow design without requiring an ECU calibration simply to install the intake.
Coupe and HTC Compatibility
The Hornet-518 is engineered for both Coupe and HTC versions of the C8 Stingray and E-Ray. Halltech specifies that HTC installation requires the top-center rivnut on the access panel to be drilled out. The system otherwise serves as a direct cold air intake replacement while reusing multiple factory components and retaining factory mounting locations.
