All,

Will the 1 inch Spacer/Riser ICE Billet Fit on CTS-V lid, under the stock hood with Strut tower brace?

This is the spacer: LSA Supercharger Lid Spacer CTSV ZL1 1" Hat Riser Plate | 551119-1 - ICT Billet

I understand that the strut tower brace will need to be shimmed to fit the 1 inch higher CTS-V lid, due to the 1 inch riser spacer, but will everything clear the stock hood then?

With the cost of the ZL1 lid I wanted to stay with stock CTS-V lid, do the Aluminum reinforced Brick TIG plates and use this 1 inch spacer. Also I was going to Port the inside of the top of the CTS-V lid and remove all those Cast lines to flow well.

Does the Spacer reduce Boost level and create more HP/Torque on Modified LSA that need the airflow??

Yes, I have read the other posts and not really seen information in years and nothing definitive either way about specific fit and if it works, so I started this thread. Because it has to fit under my hood to be a viable option.

Thank you for any help!

Get some playdoh and put some on each corner of the lid.

Close your hood.

Open your hood.

Measure how thick the remaining playdoh is.

Pro-tip: cover the top of the playdoh with tape so it doesn't stick to the hood liner.
