ok ok.. so i finally got my intake today.. and installed it.... dunno if its psychological but the truck feels like it has a bit more power. Well at least it the truck seems less sluggish on acceleration. Ok KKM gave me this rubber ring thingy, and was wondering what it was for... Any of you out there know what it is for? I have a feeling it mite be for future installtion of a custom intake arm tube. Second, I was given this black metal sort of bracket, what am i suppose to do with it?? All I did was mount the filter (which has the mounting bracket on it)and the 4 bolts. Dunno what those other pieces are for.. Someone let me know!!! thanks!
