I have a 1997 LT-1 that I am installing a NX Maf kit on. I have a Trick Flow elbow and a SLP cold air kit. My problem is that it does not fit together. It is about three inches to long so the air filters cannot drop in the hole. Is there a cold air kit that is shorter?

 

trim the CAI

 

The NX maff kit should not be playing a role in fitment issues. All it does is replace the factory mass air ends. Like ray said. It sounds like you are needing to do some trimming though.
