Special Order Item
These LT4 specific supercharger covers are intended as a quick and easy upgrade over the restrictive early LT4 covers that are used on the 2015-2016 C7 Z06 and the 2016-2019 CTS-V. The inside of the lid has been contoured to provide smooth airflow transition both out of the blower and into the supercharger mating surface. The flange is specifically made to match the geometry of the blower flange. Gains of over 25whp were made by just swapping this lid with no tuning changes. Tuning may be required and gains may vary depending upon your modifications.
This lid has been specifically designed to clear the factory strut bar on the 2016-2019 CTS-V without the need to modify the strut bar or shim it. Factory plastics will not fit, and the factory fuel line clips will not secure back down on the bolts unless you get the optional $12 stand-offs.
A set of new seals is available as a purchase option, and custom text engraving is available. We will not engrave large text/logos into the lids. These are made to order, but we will try to keep them prepped to expedite shipping.
Production units do not have the engravings shown in the photos. There are two example photos of the engravings, one in bright light and one in dim light. The top is machined, the middle is laser dark, and the bottom is laser white.
