Halltech Systems C6 Killer Bee MF Conversion Package - S&B Blue Dry Filter - MF108 Black XLPE - No NOMEX Sleeve - 103mm Throttle Body - PCV Hole in Hose (2005 - 2007 Chevrolet Corvette C6 LS2) - KBLS2CONV
Give your 2005-2007 Chevrolet Corvette C6 LS2 a serious induction upgrade with the Halltech KBLS2CONV Killer Bee MF Conversion Package, configured here with the larger MF108 Black XLPE bridge, S&B Blue Dry Filter, 103 mm throttle-body setup, and PCV hole in the throttle-body hose. This version does not include the separate external NOMEX intake-tube sleeve. More than a conventional 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 MF108 increases the nominal internal diameter at the MAF sensor to 108 mm and provides 9,161 square mm of cross-sectional area, approximately 10 percent more MAF area than the stock-size 103 mm configuration. For the throttle-body connection, Halltech's Flex-Lock 4.5-to-4.25-inch reducing hump hose is designed to connect the Killer Bee intake to a Nick Williams 103 mm throttle body. The hose uses seven-layer NOMEX-reinforced silicone construction, a compliant hump section, and internal grip ridges for secure engagement. Tuning is mandatory because KBLS2CONV requires MAF table conversion for the probe-style LS2 MAF conversion, while the larger MF108 MAF section also requires proper calibration.

MF108 Black XLPE Performance Bridge
The MF108 is Halltech's larger-MAF option for the Killer Bee MF system. It measures a nominal 108 mm internally at the MAF sensor and provides 9,161 square mm of cross-sectional area, approximately 10 percent more area than the stock-size 103 mm configuration. The increased MAF area gives performance-oriented LS2 combinations additional intake airflow capacity compared with the MF103 bridge.
The larger MAF section also changes the calibration requirements. The MF108 requires tuning because of its increased MAF cross-sectional area. In the KBLS2CONV package, that requirement is combined with the MAF table conversion already necessary when converting the 2005-2007 LS2 to the later probe-style MAF sensor arrangement.
103 mm Throttle-Body and PCV Configuration
This KBLS2CONV configuration is set up for a Nick Williams 103 mm throttle body using Halltech's Flex-Lock 4.5-to-4.25-inch reducing hump hose. The intake end has a 4.5-inch ID to fit the Killer Bee intake bridge, while the throttle-body end has a 4.25-inch ID for the 103 mm throttle body. The hose measures 3 inches long with a nominal .142-inch wall thickness and includes two stainless steel hose clamps.
Halltech's Flex-Lock design uses seven-layer NOMEX-reinforced silicone construction with a compliant hump section that accommodates engine movement and torque. Internal grip ridges at both ends increase mechanical engagement with the intake tube and throttle body. This specific configuration is ordered with the PCV hole in the throttle-body hose for PCV capability. The PCV elbow fitting is a separate selectable item and should not be assumed to be included solely because the hose has the PCV hole.
The NOMEX reinforcement within the Flex-Lock throttle-body hose is separate from Halltech's optional external intake-tube sleeve. This configuration does not include the separate external NOMEX sleeve.
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 Blue Dry Filter
This configuration uses Halltech's S&B Blue Dry Filter, providing an oil-free filter option that does not require filter oil. It is paired with the larger MF108 Black XLPE bridge and 103 mm throttle-body setup for a performance-oriented Killer Bee conversion package built around increased MAF area and a larger throttle-body combination.
MAF Table Conversion and Tuning Required
Tuning is mandatory with this KBLS2CONV MF108 configuration for two reasons. First, KBLS2CONV converts the 2005-2007 LS2 to a probe-style MAF sensor arrangement and therefore requires MAF table conversion. Second, the MF108 increases the MAF section to a nominal 108 mm and 9,161 square mm, approximately 10 percent more area than the stock-size configuration, which requires proper MAF recalibration.
Halltech states that stock LS7 Z06 MAF tables can be used as a starting point to get the LS2 conversion 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.
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 air toward the filter, stating that the modification is unnecessary and can cause lean codes and surging.

FAQs
Does the 103 mm throttle-body option change the MF108 MAF size?
No. The intake still uses Halltech's MF108 Black XLPE bridge with a nominal 108 mm internal diameter at the MAF sensor. The 103 mm specification refers to the Nick Williams throttle-body configuration and its connecting hose, not the MAF section.
Does this MF108 103 mm throttle-body configuration require tuning?
Yes. KBLS2CONV requires MAF table conversion because it converts the LS2 to a probe-style MAF arrangement, and the MF108's larger 108 mm MAF cross section also requires proper calibration.
