Halltech Systems C6 Killer Bee MF Conversion Package - S&B Red Oiled Filter - MF103 Black XLPE - No NOMEX Sleeve - 103mm Throttle Body - PCV Hole in Hose (2005 - 2007 Chevrolet Corvette C6 LS2) - KBLS2CONV
Upgrade your 2005-2007 Chevrolet Corvette C6 LS2 with the Halltech KBLS2CONV Killer Bee MF Conversion Package, configured here with the MF103 Black XLPE bridge, S&B Red Oiled Filter, and a Nick Williams 103 mm throttle body connection. This version also includes the PCV hole in the throttle-body hose while deleting the separate external NOMEX intake-tube sleeve. More than a basic cold air intake, KBLS2CONV converts the LS2 to Halltech's later probe-style MAF arrangement and includes the H108124 MAF adapter harness and proprietary Beehive heat shield.
The MF103 maintains a nominal 103 mm internal diameter at the MAF sensor with 8,332 square mm of cross-sectional area, matching the stock-size MAF cross section. For the Nick Williams 103 mm throttle body, Halltech uses its Flex-Lock 4.5-to-4.25-inch reducing hump hose. This 3-inch connector features seven-layer NOMEX-reinforced silicone construction, a compliant hump section to accommodate engine movement and torque, internal grip ridges for positive engagement, and two stainless steel hose clamps. The hose in this configuration includes the PCV hole. Despite the MF103's stock-size MAF cross section, KBLS2CONV still requires MAF table conversion and tuning because of the LS2 probe-style MAF conversion.

MF103 Black XLPE Bridge
The MF103 uses a nominal 103 mm internal diameter at the MAF sensor, providing 8,332 square mm of cross-sectional area and maintaining the stock-size MAF cross section. This gives the KBLS2CONV Halltech's MF103 Killer Bee bridge architecture without moving to the larger 108 mm MAF section of the MF108.
The MF103 bridge size should not be confused with the tuning requirements of the complete LS2 conversion package. Although the MF103 maintains the stock-size MAF cross section, KBLS2CONV still requires tuning because the system converts the 2005-2007 LS2 to a probe-style MAF arrangement.
103 mm Throttle-Body and PCV Configuration
This version is configured for a Nick Williams 103 mm throttle body using Halltech's Flex-Lock 4.5-to-4.25-inch reducing hump hose. The connector measures 4.5 inches ID at the Killer Bee intake end and 4.25 inches ID at the throttle-body end. It is 3 inches long with a nominal .142-inch thickness and includes two stainless steel hose clamps.
Halltech's Flex-Lock design uses seven-layer NOMEX-reinforced silicone, a compliant hump section, and internal grip ridges. The hump provides controlled flexibility to accommodate engine movement and torque, while the grip ridges increase mechanical engagement at the intake and throttle-body connections. This specific hose configuration includes the PCV hole for PCV capability. The PCV elbow fitting is available separately and should not be assumed to be included solely because the hose has the PCV hole.
LS2 Probe-Style MAF Conversion
The KBLS2CONV is more than a conventional cold air intake. Halltech designed the package to convert the 2005-2007 C6 LS2 to a later probe-style MAF arrangement. It includes a probe-style LS3-style MAF sensor and Halltech's H108124 Hi-Density 5-pin-to-GT MAF adapter harness, providing the key hardware required for the LS2 MAF conversion.
S&B Red Oiled Filter
This configuration uses Halltech's S&B Red Oiled Filter, pairing the oiled filter option with the MF103 Black XLPE bridge and Nick Williams 103 mm throttle-body configuration. It gives LS2 owners a complete Killer Bee conversion combination built around Halltech's stock-size MF103 MAF section while supporting the larger 103 mm throttle body.
MAF Table Conversion and Tuning Required
This KBLS2CONV configuration requires tuning. Even though the MF103 maintains the stock-size 103 mm MAF cross section, the LS2 conversion changes the vehicle to a probe-style MAF sensor and requires MAF table conversion. Halltech states that stock LS7 Z06 MAF tables can be used as a starting point to get the vehicle running, but additional calibration adjustment may be required for the individual vehicle.
Halltech primarily intends this conversion package for installing dealers or experienced users with the appropriate tuning software and knowledge. It should not be treated as the same plug-and-play application as Halltech's standard MF103 intake for later C6 LS3 and LS7 applications.
Halltech Beehive Heat Shield
The package includes Halltech's proprietary Beehive heat shield as part of the LS2 conversion system. Halltech specifically recommends against cutting additional holes in the radiator shroud to direct more air toward the filter, stating that the modification is unnecessary and can cause lean codes and surging.

FAQs
Is this KBLS2CONV configured for a Nick Williams 103 mm throttle body?
Yes. Halltech's Flex-Lock reducing hump hose connects the Killer Bee intake to a Nick Williams 103 mm throttle body. The hose has a 4.5-inch intake-end ID, 4.25-inch throttle-body-end ID, and is 3 inches long.
Does this configuration include the PCV hole, and does it still require tuning?
Yes. The throttle-body hose is configured with the PCV hole, although the separate PCV elbow fitting should not be assumed to be included. Tuning and MAF table conversion are required because KBLS2CONV converts the LS2 to the probe-style MAF arrangement.
