Halltech Systems Stingray LT1 Cold Air Intake System - TKO Attack Blue Dry Nano Filter - No NOMEX Sleeve - 103mm 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, a 103mm throttle-body setup, and a hose configured for two PCV lines. It is a performance-focused combination for C7 owners moving beyond the stock throttle body while choosing Halltech's proprietary dry nano filtration and matching the intake to a two-PCV-line vehicle.
The TKO Attack Blue Dry Nano Filter uses proprietary dry nano media made exclusively for Halltech, giving this STR configuration an oil-free filtration setup without the re-oiling requirements of traditional oiled media. Halltech's proprietary tapered C7 Stinger filter incorporates 70 pleats around the perimeter to maximize filtered surface area. This version is configured for a compatible 103mm throttle body, does not include a NOMEX sleeve, and accommodates two PCV lines. PCV configuration is especially important because Halltech notes that although GM began using one PCV line in 2017, it has encountered many 2017-2019 Corvettes that still use two PCV lines. Physically verify the vehicle 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.
103mm Throttle Body Configuration
This version of the Halltech STR is configured for a compatible 103mm throttle-body setup rather than the factory LT1 throttle body. It allows C7 Stingray and Grand Sport owners running a 103mm 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.
No NOMEX Sleeve
This version of the STR is supplied without a NOMEX intake sleeve. It is the correct configuration for buyers who want the Halltech STR with the TKO Attack Blue Dry Nano Filter, 103mm throttle-body setup, and two-PCV-line hose without adding an intake-tube thermal sleeve.
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 for use on emissions-controlled vehicles except where legally permitted for an 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 filter 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.
