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 1997-2000 C6 LS1 Conversion Package will provide airflow to 800 HP on the LS1, so it may be overkill for the average LS1. The package includes the all new C5 Killer Bee™ II Cold Air Induction System designed originally for the C6Z06, and includes our H108125 MAF Adapter 3 pin w/ IAT to GT Pigtail 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 if you email [email protected]. 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.

All systems now ship with our new dry nano filter, private labeled exclusively for Halltech by TKO (makers of the Attack Blue 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.
