2.4 and 2.2 hose IDs? Yes they are. I put a 2.4 mani and 2.4 hose on my 06 LS -- used the instructions from CED to cut and connect the hoses...actually, I wrote the instructions for CED...no kidding...LoL! The pictured engine was mine.
A hose coupler will work if you want to use a generic hose. As long as the center of the coupler is non-restrictive it will work fine - by restrictive it shouldn't be any smaller than necessary to insure a good seal.
