Intercooler foam inserts

[LuxST]

Noticed some people trim the foam inserts on the after market Intercooler they install and some people remove them. Is it necessary to keep them on or is it safe to remove them? Thanks.

The what?

These. I’m not sure what to call them

I opted to trim mine. I'm sure someone smarter than me on here can tell you what, if anything, they are invented for.

I believe they are there to help control airflow through vs around the radiator. Im not sure how much impact removing them would have, especially if you are adding cooling anyways.

Trim them if needed, but keep them. You want to keep the radiator stack as sealed as possible to force airflow through all of the cores, not give it a place to go around.

Good deal. Thanks for the advice.

x2 on UNBROKEN. It depends more on what Intercooler you go with. Some fit easier than others. I have the Mishimoto and didn't have to trim anything. I know the whipple usually needs some trimming.
