O yeah i forgot to mention that this piece prevents the upper intake coolant leak, it stops the coolant flow at the lower intake and prevents it from comming close to the egr tube.

So is it still working good?

yeah but i think i might have alittle leak.

see, ya use your old gasket between the insert and the lower intake but between the insert and the upper intake its sealant, i think i'm gonna get another gasket and fashion it to work between the upper intake and the insert. it seems pretty fool proof.

I got beat last nite though by my friends I30 hes got a y pipe and intake. i had him till 60 then. he just crept away. Now that i have p-envy i wanna get rocker arms or a cam so i can really feel the insert and spank that infiniti.

Are the engine temps running any lower? Could you feel the gain of HP whenever you stepped on the gas, or was it a time trial thing?

my engine temps are the same but the upper intake and throttlebody temps probably dropped. You can definatly feel this mod but it'* all in the upper mid-range to top end.
