I know that the LY6 is rectangular port and L33 is cathedrial, I finally found an intake but its off a LY6, is there any way to change the lower plenum or do I have to keep searching for another one?? These things are super hard to find out here and most I find are from the states so shipping is crazy to get it to Canada.
Any info would be great.

Thanks Mitch.

 

Why not use a NNBS 5.3 intake / TBSS intake?

 

I dont really want to go to the dealership and get spanked on a new intake so like most people I like to try and find a used one for a good deal. I found one from an LY6 for a really good price but it looks like swaping the lower plenum isnt doable so I guess I will just keep searching.

Thanks, Mitch
