Halltech Systems Black Killer Bee MF103 Cold Air Induction - S&B Red Oiled Filter - NOMEX Sleeve - 103mm Throttle Body - PCV Hole in Hose (2006 - 2013 Chevrolet Corvette C6 LS7 Z06 / 2008 - 2013 Chevrolet Corvette C6 LS3) - KBMF103
Upgrade your LS3 or LS7 C6 Corvette with Halltech's Black Killer Bee MF103 Cold Air Induction, configured for a Nick Williams 103 mm throttle body and equipped with an S&B Red Oiled Filter. The KBMF103 retains Halltech's stock-size MAF strategy with a nominal 103 mm internal diameter at the MAF sensor and 8,332 square mm of cross-sectional area. Halltech engineered the MF103 to translate the MAF tables like stock without requiring additional intake tuning. This version also includes the external NOMEX intake-tube sleeve and a PCV hole in the throttle-body hose.
Halltech's MAF-forward architecture is designed for excellent idle quality and proper MAF translation, while the Beehive heat shield helps isolate the filter and MAF sensor from hot engine-bay air. The S&B Red Oiled Filter provides Halltech's traditional oiled filtration option, and the external NOMEX sleeve adds thermal protection around the intake tube. Connection to the Nick Williams 103 mm throttle body is handled by Halltech's Flex-Lock 4.5-to-4.25-inch reducing hump hose, featuring seven-layer NOMEX-reinforced silicone construction, a compliant hump section to accommodate engine movement and torque, internal grip ridges for secure engagement, and two stainless steel hose clamps.

NOMEX Heat Protection
The included 18-inch Halltech NOMEX sleeve provides an additional thermal barrier around the intake tube. Constructed from heat-resistant DuPont NOMEX aramid fabric with stretch elastomer, the sleeve complements Halltech's Beehive heat shield by adding protection around the intake tract from high underhood temperatures. The sleeve can be trimmed or positioned as needed for access around the MAF sensor and may cover portions of the hose or filter neck depending on installation.
Flex-Lock 103 mm Throttle-Body Connection with PCV Hole
Halltech's Flex-Lock 4.5-to-4.25-inch reducing hump hose connects the Killer Bee intake to a Nick Williams 103 mm throttle body. The intake end has a 4.5-inch inside diameter, while the throttle-body end has a 4.25-inch inside diameter. The 3-inch-long hose features seven-layer NOMEX-reinforced silicone construction, a compliant hump section to accommodate engine movement and torque, and internal grip ridges for increased engagement with the intake and throttle body. Two stainless steel hose clamps are included. This configuration includes the PCV hole in the throttle-body hose for PCV capability.
No Additional Intake Tuning Required
The Killer Bee MF103 is Halltech's plug-and-play C6 induction system for the LS3 and LS7. Halltech designed the MF103 around the same nominal 103 mm internal diameter at the MAF sensor as the stock intake, allowing it to translate the MAF tables like stock without requiring additional tuning simply because the MF103 intake has been installed. Performance tuning can still be used to pursue additional horsepower and torque. With a 103 mm throttle body or other engine modifications, overall vehicle tuning requirements should be determined by the complete engine and modification combination.

FAQs
Which 103 mm throttle body is this Halltech KBMF103 configuration designed for?
Halltech identifies this 103 mm throttle-body configuration for use with the Nick Williams 103 mm throttle body. The corresponding Flex-Lock reducing hump hose has a 4.5-inch intake-end inside diameter and a 4.25-inch throttle-body-end inside diameter.
Does the Halltech KBMF103 require tuning with a 103 mm throttle body?
The MF103 intake itself does not require additional MAF tuning because Halltech retains the stock-size nominal 103 mm internal diameter at the MAF sensor. Overall vehicle tuning requirements can still depend on the 103 mm throttle body, engine combination, and other modifications.
