Halltech Killer Bee II intake kit for 2008-2010 C6 and Grand Sport Corvette with LS3 engine.
Halltech Killer Bee II Intake is the second generation Killer Bee which features many improvements over the original Killer Bee. Katech Engine Development Dyno Cell #2 provided stunning numbers never before seen with an intake system. +15 hp gain over the stock LS7 GM intake. The primary difference is that the inlet side of the Killer Bee II has been increased from 98mm to 107mm with a 4.5" o.d. flange and 4.2" i.d. The outlet side of the Killer Bee II is a full 102.5mm. The Mass Air Flow sensor mount is now a one piece integrated part of the Killer Bee II, uses the stock screws, has no steps, and is 103mm MAF Read Area. The unit is now 50% thicker than the original Killer Bee for improved strength and resistance to heat distortion. There has been substantial reshaping of the floor of the Killer Bee II for improved flow numbers and velocity, which shows up at high rpm on bigger motors. The new Halltech filter is 15" wide vs. 14" wide, with much better fitment under the Beehive. The neck of the filter is 3/4" longer than the old filter to allow the bridge maximum insertion (1.75") depth. The filter flange now features a full Bellmouth full radius velocity stack for maximum high velocity at high rpm and smooth laminar airflow at the MAF sensor. The ISO 5011 tested low restriction filter media outflows the previous filter by 25%, with more surface area than its predecessor, and a better fit under the Beehive. The Beehive is now included and is an integral component with all Killer Bee II systems to avoid loss of power due to heat soak and IAT issues causing timing reduction.
