Halltech C5 Killer Bee™ II 2001-2004 C5 LS6/LS1 Conversion Package
Because this system MUST be tuned after uploading new MAF tables, it is intended primarily for our installing dealers (it is not a DIY install unless you have the correct software and know-how).
Halltech C5 Killer Bee™ Conversion Package for the 2001-2004 C5 LS Series
Halltech High Flow Killer Bee™ II induction intake
Halltech SuperBee filter with velocity stack
Provision for your A.I.R. Pump if required (default is delete)
Halltech H108124 Adapter Hi-Density Small 5 pin to GT harness
GM new MAF sensor (probe style from the LS7/LS3)
Halltech tested MAF tables for the ECM- Please email [email protected] for the Excel tables
Test results
Facts: expect to gain +24 HP (see attached dyno) vs. the stock intake and +12 RWHP over the Vararam (see dyno) The Halltech Killer Bee™ II 2001-2004 C6 LS1/LS6 Conversion Package will provide airflow to 800 HP on the LS6/LS1, so it may be overkill for the average LS6. The package includes the all new C5 Killer Bee™ II Cold Air Induction System designed originally for the C6Z06, and includes our H108124 Hi-Density Small 5 pin to GT harness, and the probe style LS7 MAF sensor, Reprogramming the MAF curve is not optional since the new probe style MAF requires a totally different curve. We will make the MAF transfer curve tables available free of charge. They may need to be tweaked a bit, but you will get the car running with our MAF calibration tables.
We do not recommend cutting any holes in your radiator shroud (in an attempt to get more air to the filter). It is not necessary, and will cause lean codes and surging.
We've got you covered if you favor a dry filter or an oiled filter. Choose from our 4 options:
- S&B Red Oiled Filter
- S&B Blue Dry Filter
- S&B Gray Oiled High-Flow Track Filter
- TKO Attack Blue Dry Nano Filter
Halltech does not have a CA EO number for this induction system, which means it is not legal for sale in CA, unless used in off-road application, such as track racing.
Halltech C5 Venom™ & Honeycomb Screen (2001-2004 LS1/LS6 only)
Halltech's C5 Venom™ II, cut from the cloth of the all new Killer Bee™ II Z06 Cold Air Induction System this second generation intake flows more air than any induction system on the market. It utilizes the stock Mass Air Flow sensor for easy installation and seamless smooth response on the street or at the track. Starting with the wide SuperBee Halltech filter with built in velocity stack flange, the actual changes to our mold design have increased flow to the throttle body. The bridge is also made from the new KB II mold which dynoed over 13 HP on the Katech Engine Dyno. Fits 2001-2004 Corvette C5 LS1 and LS6. The MAF sensor shown is not included, but we do provide our laminar flow screen with higher flow than the stock LS1 screen. Use your stock MAF, elbow for the A.I.R. pump and wire harness.

Halltech TunnelPort
Halltech TunnelPort is the first step in opening up cold air to your C5. This is legal only in states without a front license plate law, as it replaces the front license plate.
Track only for those states. It is possible to open up more of the fascia area, running this cold air into the Halltech Killer Bee II blade MAF Conversion Package.
- Upgrade to a matte finish Carbon fiber (no clear coat applied), but it can be sanded, primed, and paint-matched to your car.
- Advertised price is the black gel-coat fiberglass version
- Separate screen always included, or preinstalled for a small fee.
Allow 1-2 weeks for shipment. Custom orders, no refunds except for shipping damage.
Halltech Honeycomb™1/8" Cell MAF Flow Straightener
Smooth the airflow. Stabilize the MAF signal.
The Halltech Honeycomb™ is a high-flow airflow straightener designed specifically for the Delphi 85mm MAF sensor used on C5 Corvettes and early C6 LS2 applications.
The aluminum honeycomb structure reduces turbulence and swirl in the airflow before it reaches the MAF sensor, helping create a more consistent airflow profile across the MAF sensing element. This is especially important with aftermarket intake systems that can introduce turbulence or uneven airflow at the MAF.
The Honeycomb™ is a direct, plug-and-play replacement that installs in about one minute using your existing factory MAF meter.
The Honeycomb™ can eliminate lean codes and surging associated with turbulent airflow at the MAF when used with aftermarket intake systems. It replaces the restrictive factory 1/16-inch honeycomb screen found in LS1–LS2 MAF applications.
High-Flow Airflow Straightening
The Honeycomb™ uses a 94mm diameter aluminum honeycomb structure with 1/8-inch cells and a 6mm thickness. The larger cell structure provides effective airflow straightening while maintaining high airflow through the MAF.
The result is a cleaner, more stable airflow path into the MAF sensor—without adding a restrictive screen to the intake.
Application
- All Delphi 85mm MAF sensors
- 2001–2004 C5 Z06 — helps eliminate lean codes and MAF-related surging caused by turbulent airflow with aftermarket intake systems
- 2005–2007 C6 LS2 base Corvette — compatible with the factory MAF system
- Replaces the factory 1/16-inch honeycomb in LS1–LS2 MAF applications
Important: The MAF sensor shown in product photos is for illustration only. The Honeycomb™ is the product being purchased; you will reuse your existing factory MAF meter.
Installation
Installation takes approximately one minute and requires no tuning or modification to the vehicle.

Important
The aluminum honeycomb structure is extremely fragile. Handle carefully. This product cannot be returned once purchased.
