Yeah, I see no reason why it wouldn't. There may be small differences in the length and arrangement.

For my '08 Denali it was:

Two 4in sections of 3in pipe (to join the elbows)
One 45 degree street elbow (connects to MAF)
One 60 degree regular elbow
One 90 degree street elbow (connects to throttle body)
Two 3in Fernco's w/clamps
One 3/8 barbed 90 degree threaded fitting
One foot of rubber 3/8 ID tubing


If I were going to build another one, I might try using a 60 degree street elbow in place of the 90 to connect to the throttle body. At least on my vehicle it kind of curls back a bit inside of the Fernco boot, making a not so smooth transition. The 90 degrees was a little too much. I think 60 would have been more ideal.

I drilled and tapped the barbed fitting into the backside of the 60 that connects to the line down near the top of the passenger side valve cover. Where the fitting goes into the 60, I used some liquid electrical tape to ensure I had an airtight seal. All of the unions are just glued with regular PVC cement.

Awesome. Thanks for the details! Yeah, much prefer less angles whenever possible!
