Halltech Systems Black Killer Bee MF103 Cold Air Induction - S&B Gray Oiled High Flow TRAK Filter - No NOMEX Sleeve - 103mm Throttle Body - No 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 the airflow capability of a 103 mm throttle-body combination while retaining the plug-and-play design of Halltech's Killer Bee MF103. The KBMF103 uses a nominal 103 mm internal diameter at the MAF sensor, matching the stock intake diameter and providing 8,332 square mm of MAF cross-sectional area. Halltech engineered the MF103 to translate the MAF tables like stock, so no additional tuning is required for the intake itself. This configuration combines the black Killer Bee MF103 with Halltech's S&B Gray Oiled High-Flow Track Filter, Nick Williams 103 mm throttle-body connection, no external NOMEX intake sleeve, and no PCV hole in the throttle-body hose.
Halltech's MAF-forward architecture is engineered for proper MAF translation and excellent idle quality, while the included Beehive heat shield isolates the air filter and MAF sensor from hot engine-bay air. The S&B Gray Oiled High-Flow Track Filter gives this combination Halltech's high-flow oiled filter option. For the Nick Williams 103 mm throttle body, Halltech uses its Flex-Lock 4.5-to-4.25-inch Reducing Hump Hose. Its seven-layer NOMEX-reinforced silicone construction combines a compliant hump section with internal grip ridges to accommodate engine movement while maintaining positive engagement at the intake and throttle body.

No Additional Intake Tuning Required
The Halltech Killer Bee MF103 is engineered as a plug-and-play intake that requires no additional tuning. Its nominal 103 mm internal diameter at the MAF sensor matches the stock intake diameter, allowing Halltech to engineer the MF103 to translate the MAF tables like stock. Halltech notes that proper performance tuning can produce additional horsepower and torque, but MAF recalibration is not required simply to install and operate the MF103. This particular version adds Halltech's connector for a Nick Williams 103 mm throttle body while retaining the MF103 intake's stock-size MAF section.
Important Installation Information
This configuration uses Halltech's 4.5-to-4.25-inch Flex-Lock reducing hump hose for the Nick Williams 103 mm throttle body and is specified without a PCV hole. It also does not include the optional external NOMEX intake sleeve. Halltech recommends against cutting holes in the Corvette radiator shroud to direct additional air toward the filter because the modification is unnecessary and can cause lean codes and surging.

FAQs
Which 103 mm throttle body is this Halltech KBMF103 configuration designed for?
Halltech specifies its 103 mm Flex-Lock connector for the Nick Williams 103 mm throttle body. The hose has a 4.5-inch ID at the Killer Bee intake and a 4.25-inch ID at the throttle body, measures 3 inches long, and includes two stainless steel clamps. This specific configuration is supplied without a PCV hole in the hose.
Does the Halltech Killer Bee MF103 require tuning when used with a 103 mm throttle body?
Halltech designs the MF103 intake itself to require no additional tuning because its nominal 103 mm internal diameter at the MAF sensor matches the stock intake diameter. The 103 mm throttle-body connector does not enlarge the MF103 MAF section. Tuning requirements for an individual Corvette can still depend on the vehicle's complete engine and modification combination.
