Volant 15860150 Closed Box Cold Air Intake Kit for 2005-2008 Pontiac GTO 6.0L

Vehicle Fitment

• 2005-2008 Pontiac GTO (Base, 6.0L V8 LS2)

Fitment Notes

• CARB EO # D-526-7 applies to 2005-2006 Pontiac GTO only; this system is not legal for sale or use in California or other CARB-regulated states for 2007-2008 model years
• Direct-fit replacement for the factory air box, resonator, and intake tube - no modifications required
• Designed specifically for the GM LS2 6.0L V8 engine as installed in the 2005-2008 GTO

Features

• High-velocity venturi filter adapter provides a smooth, optimized transition through the MAF sensor into the intake tube, improving airflow measurement accuracy and total flow volume over the factory rubber tubing
• Oversized cross-link polyethylene Cool Air Box is engineered larger than the OEM unit and features a larger opening to collect a higher volume of colder ambient air drawn from outside the engine bay
• Bottom-mounted air scoop on the filter box continuously channels cool air from beneath the vehicle, supplementing fender-fed airflow for sustained cold air supply under hard acceleration
• Cross-link polyethylene air duct features larger diameter tubing, optimized bend geometry, and smooth interior transitions to minimize turbulence and maximize airflow velocity to the throttle body
• Included Pro5 MaxFlow oiled cotton gauze air filter features 5 layers of high-grade textile media pleated between top and bottom aluminum screens for maximum filtration efficiency with minimal restriction
• Filter arrives pre-oiled and ready to install; reservice interval is every 10,000 miles with re-oiling and every 50,000 miles with a full cleaning using Volant maintenance kit
• Closed box design thermally isolates the filter from underhood heat, maintaining consistent intake air temperature for more predictable power delivery compared to open-element systems
• High-performance silicone connectors and stainless steel marine-grade clamps ensure airtight sealing and long-term durability under heat cycling and vibration
• Factory-tuned system designed to work with the GTO's stock MAF sensor and PCM calibration - no tune required for installation

Product Description

The Volant 15860150 is a closed box cold air intake system engineered specifically for the 2005-2008 Pontiac GTO equipped with the 6.0L LS2 V8. Unlike open-element intake kits that draw hot air directly from the engine bay, Volant's Cool Air Box design physically encloses and thermally isolates the filter, pulling ambient air from outside the engine compartment through a bottom-mounted air scoop and fender-area inlet. This approach delivers a consistent charge of cooler, denser air to the LS2, translating to improved throttle response and more reliable power output under sustained high-load conditions. The cross-link polyethylene air duct replaces the restrictive factory rubber tubing and resonator box with a larger-diameter, smoother-flowing passage that allows air to reach the throttle body more efficiently.

At the heart of the system is Volant's Pro5 MaxFlow air filter - a 5-layer oiled cotton gauze unit constructed with high-grade textile media sandwiched between aluminum screens. This filter design delivers exceptional filtration while flowing more air than paper OEM elements, and it is fully cleanable and reusable. The high-velocity venturi filter adapter provides a smooth, optimized air transition through the MAF sensor housing, ensuring accurate mass airflow readings and compatibility with the GTO's factory PCM calibration without the need for a tune. Stainless steel marine-grade clamps and high-performance silicone connectors secure every connection point in the system, providing an airtight seal that holds up to the heat cycling and vibration typical of high-performance street driving and track use.

Installation is a direct-fit bolt-on process using the factory mounting locations, and everything required to complete the swap is included in the kit. The system is designed for GTO owners who want a meaningful, seat-of-the-pants performance improvement without sacrificing engine protection or daily drivability. For 2005-2006 model year vehicles, this system carries CARB Executive Order # D-526-7, confirming emissions compliance in California and other CARB-regulated states for those years. Owners of 2007-2008 GTO models should verify local emissions regulations prior to installation, as the CARB exemption does not extend to those years.
