Milled and Reinforced ZL1 Lid for 2009-2015 Cadillac CTS-V

A common upgrade for the CTS-V is now available from Dedicated Motorsports. The ZL1 Blower lid sports a larger volume plenum, higher density/ more efficient intercooler core and a LESS restrictive airflow path on the intercooler exit. It’s easy to see why the factory rated Horsepower of the ZL1 Camaro was 24 Hp higher than the CTS-V LSA. This additional volume and lid height requires the ZL1 lids to be milled to allow for hood clearance. Which brings us to the process. Not only do we mill the deck but we radius the front edge for additional hood clearance followed by removing the 4 front bosses that are unused by the CTS-V along with a tab that blocks the CTS-V Fuel rail bolt. This allows space for the -12an fittings and hose to stay close to the blower lid and away from the fuel rail and hood (another clearance issue).

Includes our billet version manifold that is CNC machined from 6061 aluminum and hard anodized for a long life in the harsh environment of the LSA cooling system. Comes standard with -12 ORB threads and can accept a -16an to -12 ORB adapter.

Another common problem associated with running increased boost levels on the LSA PD blower is the collapse of the intercooler core or “brick”. All Dedicated Motorsports Milled ZL1 lids come with a reinforced brick standard.

  • CNC Billet Black Anodized Manifold (ORB)
  • Reinforced and Pressure Tested Intercooler Core

  • Includes: Intercooler brick, Baro Sensor, Map Sensor, Billet coolant manifold, Gasket and Hardware.

*** Please be advised: Some sort of hose and fittings will be required to install this lid. We've supplied a couple options below.

Option 1: 20' of pushlock hose - This kit uses a high quality 3/4 heater hose and pushlock fittings. This is very easy to work with and can be used to plumb non trunk mounted reservoir cooling systems

Option 2: 20' of braided hose - This kit is the same as option 1 but uses a -12an (3/4) nylon braided hose with an inner steel braiding, its very strong and resistant to abrasion but is harder to cut and work with.

Option 3: This is a very simple connection system designed to connect to the factory CTS-V hardline and retains the OEM filler reservoir. It includes about 8 feet of high quality 3/4 heater hose and pushlock fittings
