Halltech Systems Stingray LT1 Cold Air Intake System - TKO Attack Blue Dry Nano 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 induction system around a larger throttle-body combination with the Halltech Systems STR Cold Air Intake System. Designed for the 2014-2019 Chevrolet Corvette C7 Stingray and 2017-2019 Grand Sport, this STR configuration combines Halltech's purpose-built C7 Stinger intake architecture with the TKO Attack Blue Dry Nano Filter, NOMEX heat-barrier sleeve, 112mm throttle-body setup, and a hose configured for two PCV lines. The result is a carefully matched STR package for C7 owners who want dry nano filtration, a larger throttle-body configuration, added intake-tube thermal insulation, and the correct plumbing for a two-PCV-line LT1.
The TKO Attack Blue Dry Nano Filter uses proprietary dry nano media made exclusively for Halltech, providing oil-free filtration without the re-oiling requirements of traditional oiled filter media. Halltech's proprietary tapered C7 Stinger filter incorporates 70 pleats around the perimeter to maximize filtered surface area. This version adds the NOMEX sleeve to help insulate the intake tract and is configured for a compatible 112mm throttle body and two PCV lines. Because Halltech has encountered 2017-2019 Corvettes with both one-line and two-line PCV arrangements, physically verify the vehicle's actual PCV configuration before ordering.

TKO Attack Blue Dry Nano Filter
This STR configuration uses the TKO Attack Blue Dry Nano Filter, Halltech's proprietary dry nano-media option for its C7 Stinger intake systems. The filter media is made exclusively for Halltech by Attack Blue and provides an oil-free alternative to the available oiled filter choices. Because it uses dry media, there is no filter-oiling step during normal servicing.
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 allows C7 Stingray and Grand Sport owners running a 112mm throttle body to select the STR configuration intended to match their larger throttle-body combination.
Two PCV Line Configuration
This STR is specifically configured for C7 LT1 applications requiring two PCV lines in the hose. Halltech emphasizes that the correct PCV configuration cannot reliably be determined from model year alone. GM began using one PCV line in 2017, but Halltech has encountered many 2017-2019 Corvettes that still use two PCV lines. Physically inspect the vehicle and verify its actual PCV-line count before ordering.
NOMEX Heat-Barrier Sleeve
This configuration adds a NOMEX heat-barrier sleeve around the intake tract. The sleeve provides an additional insulating layer between the intake system and surrounding underhood heat, making it a useful addition for a performance-oriented C7 induction package where managing heat transfer into the intake tract is a priority.
Halltech C7 Stinger Filter Design
The filter used with the STR is not a generic universal element. Halltech identifies its C7 Stinger replacement filter as a proprietary design made exclusively for Halltech by S&B and TKO and specifically designed to fit Halltech C7 Stinger intake systems. Its tapered design incorporates 70 pleats around the perimeter to maximize filtered surface area.
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
Does the TKO Attack Blue Dry Nano Filter require filter oil?
No. The TKO Attack Blue filter uses proprietary dry nano media made exclusively for Halltech, so filter oil is not required during servicing. It provides an oil-free filtration option while retaining Halltech's proprietary tapered C7 Stinger filter design.
How do I know whether my C7 Corvette needs the two-PCV-line Halltech STR?
Physically inspect the vehicle and count the PCV lines before ordering. Halltech states that GM began using one PCV line in 2017, but it has encountered many 2017-2019 Corvettes with two PCV lines. This STR configuration is specifically set up for vehicles requiring two PCV lines.
