i grinded all the ribs down and had no problems, make sure you get the ones underneath the foam as well. I dont know what their purpose it but so far everything is fine.

there is foam on the bottom of the stocker you can use, my SLP intake didnt come with any new foam either. But i didnt have to grind the ribs off of mine and it fit perfect no leaks and sealed flush no problem, maybe SLP fixed that little problem.

ribs are there to add strength to the intake, I would just grind down the areas you need to clear the coolant tubes, not everywhere!

The foams purpose it looks to me is to keep water out of that area and from the knock sensors, and it looks to me that the ribs on the slp version are really small and fit perfect. hell i didnt even have to bend the coolant lines at all, i was really shocked and impressed with how much better my car responds and drives now.

You can grind them down, I did it to my old LS6 intake and ran it for a while and it was all good. Just grind the spots that you need to.

senicalj4579, I grinded every rib down and then used some weatherstripping foam where the old foam was. It fit perfectly and I have no leaks or problems at all. For me it was easier to remove them all than to keep tring to guess which ones needed removed.

I ground mine down too, but only the ones I needed to. I didn't have to guess though, the old intake's foam had a perfect little design in it where the pipes were .

So far so good, nothing bad has happened.

yeah man, the thing is i got the old maifold still on my car and the ls6 on my workbench. its just to much of a pain to have to **** around with the new intake so i'm just gonna cut all the ribs down and then take off the old one and slide the new into place no question and no guessing.

about the foam.......i didnt have any clue there was any underthere in the first place. do you think the ribs are there to help hold this foam in there or something? (just guesing) anyway.... why didnt you use the old foam?

Thats what i did. I don't see how there would be any way to really even guess where the lines go very well in there. It worked pretty well. I just tried guessing from the foam and then I would go over and set it in place and feel if anything felt like it was still touching. I did still have to push the lines down a very small amount (1/8" at most maybe). Worked pretty well in my opinion, and I'm not worried about it at all.
