Gron86

My apologies. Didn’t realize I posted twice. I simply need to know if they are interchangeable. I have used airaid/afe spacers in past vehicles and while I admit they may not increase power, they do provide better throttle response from my past experiences.

Anybody know if the throttle bodies from both engines are the same? I’m looking for a throttle body spacer for my Yukon Denali, however every dealer is sold out of the l86 spacer. Will a spacer for a lT1 fit the l86? They look identical and all mounting points look the same. But I cannot confirm. thanks.
