Halltech Killer Bee™ II is our second generation Killer Bee™, which features many improvements over the Killer Bee™. Katech Engine Development dyno just in shows +15 HP gain over the stock LS7 GM intake. Fits all C6 Corvettes including the 05-07 C6 LS2* 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 to match the 102mm throttle body, and dial in perfect Long Term Fuel Trims. By comparison, the K&N Z06 intake has a 94mm outlet and becomes the point of restriction when using a larger throttle body/intake manifold. No tuning required at all for this intake system, but if you do decide to tune, count on +33 RWHP shown in the dyno. Click on Larger Picture for the dynos. 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 .150" thick or 50% thicker than the 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. 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. Our ISO 5011 Tested low restriction filter media outflows the previous filter by 10%, with more surface area than its predecessor. The Beehive™ is an integral component and included with all Killer Bee™ II systems to avoid loss of power due to heat soak and IAT issues causing timing reduction. Testing by Katech to follow. NO TUNING REQUIRED, but more power can be achieved with proper Halltech e-mailtune® remote tuning. Pre-order now. We already have a waiting list. *Only the 05-07 LS2 will require our Mass Airflow Conversion Kit CONVLS7, and SCT Tuner or e-mailtune® to recalibrate the MAF tables. Select the conversion package under Accessories for 05-07 C6s. The Killer Bee™ II CF112 Carbon Fiber version, just laid down +33 RWHP/26lb-ft tq on a brand new 2010 Z06 on March 4th, with MAF re-calibration only.*
* Tuning in not required for the Killer Bee™ II, but the CF112 Carbon Fiber version requires MAF re-cal tuning due to its larger inlet and outlet. Both intakes dynoed at +14 on Katech's Engine Dyno.
