Halltech's Super Bee™ MF103 Ram Air Induction takes the lead away from Vararam with this run. Application-2008-2012 C6 LS3/2006-2012 C6Z06. The MF103 requires NO TUNING and has better than stock idle manners due to the MAF forward design and integrated velocity stack built into the filter flange. Made from roto-molded cross link polyethylene it brings the same horsepower to your LS3 as you have seen the past year in the Super Bee™ CF102 or CF112 Carbon. Size matters, and the Super Bee™ MF103 is 102.5mm at the MAF read and at the exit, meaning it is larger than the massive Williams Performance 102 Throttle Body, but comes with the connector hose for the stock throttle body, but can be ordered with the larger connector hose for the WP102 TB. Did we mention NO TUNING! Halltech's roto-molded version of the Super Bee™ FG102 features the same filter and Beehive™ as the Carbon and Fiberglass version as well as the Killer Bee™ II. Since early 2010, the Super Bee™ has been the dominant Halltech induction system, with staggering horsepower and torque numbers that have literally shattered all records. From engine dynos to chassis dynos, you will not find more power from any intake made. Katech just built the "Highest rwhp NA car ever built by Katech" and "Highest rwhp NA car ever on Vector Motorsports' dyno" according to Jason Harding of Katech Performance using the Super Bee™ induction system on their #48 Track Attack Z06. Jerry's Chevrolet picked up 33 RWHP with just the Super Bee™ FG102 back in early 2010, with minor MAF table adjustments. Available now. ***Some pictures depict the stock MAF sensor installed to illustrate our 7" MAF forward extension cord. The MAF sensor and PCV plastic nipple are not included, since they are swapped from the stock intake system. You will need an 8mm and 7mm nut-driver to install this intake system. You may need to include the Security TORX bit shown as an accessory in the side bar to remove your stock MAF screws. 2011 LS3s may have the 5 point Security Plus screws from GM. Full Ram Air requires some cutting of the radiator shroud, which can be done without removing the shroud. See Installation, Beehive™ Ram Air Port Installation.
