OldRedMack Posted May 22, 2021 Share Posted May 22, 2021 I chucked mine in the scrap bin. Use the old style and get an s400 turbo. Quote Link to comment https://www.bigmacktrucks.com/topic/66727-2004-ai-engine-exhaust-manifold/#findComment-474161 Share on other sites More sharing options...
br549 Posted May 22, 2021 Author Share Posted May 22, 2021 Thanks BG for the offer, could not wait. Put the old style manifold on it and used the same AMI turbo back. took truck down the road empty, seems ok, time will tell.
