I have a spare set of the factory UIM runners found on the inside of the L36 and L26 UIM (same runners for both engines).

I have ZERO use and ZERO need for these. I know I've seen thread of people who broke theirs and others of people trying air flow mods (never with a conclusion).

These are free, anyone interested has to just pay the shipping (guessing $15). If no one wants them by trash day on 1/21, they leave my garage for good.

 

Almost trash day. If anyone wants them, speak soon

 

So trash day came and went, I forgot to toss these. Last chance (pending I remember next trash day) if anyone is interested. Trash pick up is Tuesday 1/29.

Just pay the shipping and it's yours.

 

is it an upgrade over stock/ easy to install

 

These are straight up stock intake runners (not an upgrade).
I'm posting them as some people damage theirs OR some have wanted to modify a set. Well here's a chance to do so.
I am guessing it's $10-$15 to ship.
