7) INTAKE
For the intake, I intended to weld up a custom 4” aluminum unit. However the Friday afternoon before the Christmas holiday, I realized I was almost out of Argon shield gas and everything had already closed…AAARRGH.
I had a leftover New Era CAI from my old CTS-V wagon. I did a couple of test fits and the MAF and PCV port was in the perfect location. The filter also fell perfectly into the dead space where the old airbox resided. Looked like a plan!
The only minor issue was that the CTS-V uses a different MAF style than the LS7 card MAF I intended to use. Luckily in my box of 4” mandrel bent aluminum tubes was an LS7 Card MAF plate. It looked like I could machine that down to make an adapter plate.
I drilled and counterbored the aluminum adapter plate for some small M5 stainless cap screws. On the intake itself, I cut off the mount bosses for the old CTS-V MAF then match drilled and tapped mount holes. I also had to remove some material to accommodate the LS7 MAF width. I sprayed some engine enamel on the areas I ground down and installed the new interface plate with black sensor safe RTV.
Here’s the finished result of the MAF adapter.
Now installed in place with the IAT breakout cable
The PCV connector needs to be rotated to connect properly to the intake. It required the use of a heat gun. It is on there really tight.
Hood closed and picture taken looking forward to check hood clearance; there’s plenty.
Intake looks pretty good (but I’m a little biased).
