If you're a do-it-yourself kind of enthusiast, then the FiTech LS3 Ultimate LS Self-Tuning Intake Kit 70012 with Transmission Control 500HP is perfect for you. Get back on the street with this conversion kit to jump your LS3 engine up to speed with the rest of the aftermarket world. Whether you're working on a Restomod or your latest vehicle, this feature is suitable for 4L60, 4L65, 4L80 or 4L85 GM transmissions.
The Ultimate LS 500HP Kit with trans control for LS3 engines is a complete self-tuning induction system for LS engines, ready-to-go. Rather than source mismatched parts and modifying the harnesses, FiTech gives you the Ultimate EFI to ditch that old factory hardware or top off that fresh long block.
This intake manifold Kit comes with electronic transmission control that can be used when operating a GM electronically controlled automatic transmission. The Ultimate LS ECU has the ability to control the shift point and shift firmness when to downshift properly. If using transmission control connect the two sides of the trans connector to the sub-harness and connect this to the connector on the transmission. Once connected to the transmission you are ready. If not using transmission control leave the connectors untouched.
