Halltech Systems Stingray LT1 Cold Air Intake System - S&B Red Oiled Filter - NOMEX Sleeve - 112mm Throttle Body - Two PCV Lines in Hose (2014 - 2019 Chevrolet Corvette C7 Stingray / 2017 - 2019 Grand Sport) - STR
Build your LT1-powered C7 Corvette around a larger throttle-body induction package with the Halltech Systems STR Cold Air Intake System. Designed for the 2014-2019 Chevrolet Corvette C7 Stingray and 2017-2019 Grand Sport, this configuration combines Halltech's purpose-built C7 Stinger intake architecture with the S&B Red Oiled Filter, a 112mm throttle-body setup, NOMEX heat-barrier sleeve, and a hose configured for two PCV lines. It is a performance-focused STR combination for C7 owners running a large 112mm throttle body who want serviceable oiled filtration, added thermal insulation around the intake tract, and the correct plumbing for a two-PCV-line LT1.
The S&B Red Oiled Filter provides a reusable, serviceable oiled-media filtration setup, while the 112mm configuration matches the STR to a compatible larger throttle body. Halltech's NOMEX sleeve adds a lightweight thermal barrier around the intake tube to help isolate it from surrounding engine-compartment heat. This version is also configured for two PCV lines. Because Halltech has encountered later C7 Corvettes with both one-line and two-line PCV arrangements, physically verify the vehicle's actual PCV-line count before ordering.

S&B Red Oiled Filter
This STR configuration uses the S&B Red Oiled Filter, Halltech's traditional oiled-media filter option. Its serviceable design allows the filter to be cleaned and properly re-oiled as part of routine maintenance, making it a strong choice for enthusiasts who prefer a reusable oiled filter in their C7 induction system.
112mm Throttle Body Configuration
This version of the Halltech STR is configured for a compatible 112mm throttle-body setup rather than the factory LT1 throttle body. It gives C7 Stingray and Grand Sport owners running a 112mm throttle body an STR configuration matched to their larger throttle-body combination, making the intake ready for an induction system built around the larger throttle-body opening.
Two PCV Line Configuration
This STR is specifically configured for C7 LT1 applications requiring two PCV lines in the hose. Do not determine the correct PCV configuration solely by model year. Halltech states that GM began using one PCV line in 2017, but it has encountered many 2017-2019 Corvettes that still use two PCV lines. Physically inspect the vehicle and confirm its actual PCV-line count before ordering.
NOMEX Heat-Barrier Sleeve
This configuration includes Halltech's black 18-inch NOMEX heat-barrier sleeve. Constructed from heat-resistant DuPont Nomex aramid fabric combined with a stretch elastomer, the sleeve creates a lightweight thermal barrier around the intake tube to help isolate the intake tract from engine-compartment heat. Depending on positioning, Halltech notes that the sleeve can also extend over the throttle-body hose and/or filter neck.
Installation Note
Older Halltech installation material may show an F-panel seal. Halltech states that this seal is no longer needed and is therefore no longer supplied with the STR kit. The corresponding F-panel-seal step shown in older installation instructions can be ignored.
Emissions Notice
Halltech states that the STR does not have a California Executive Order number and is not legal for sale in California unless used in a qualifying off-road application such as track racing. Check applicable state and local emissions requirements before ordering or installing this intake.

FAQs
Is this Halltech STR designed for a 112mm throttle body?
Yes. This specific STR configuration is set up for a compatible 112mm throttle body rather than the factory LT1 throttle body. It combines that 112mm configuration with the S&B Red Oiled Filter, NOMEX sleeve, and two-PCV-line hose.
How do I know whether my C7 Corvette needs the two-PCV-line Halltech STR?
Physically inspect the vehicle and count its PCV lines before ordering. Halltech states that GM began using one PCV line in 2017, but it has encountered many 2017-2019 Corvettes that still have two PCV lines. This STR configuration is specifically set up for cars requiring two PCV lines.
