I just installed a Fluidyne radiator. Now I'm putting in an M2 intake. Why does the M2 intake only have 6 hose connections when the stock intake has 7? There isn't a hose on the side of the M2. Not only that, but it's been so long since I took off the stock intake that I don't even remember where the other end of the side hose went. So basically I have an extra hose and no where to put it. Do I need this one?
Also, what do I do with the hole in front of the IC that used to lead to the stock air intake? Should I cover this hole to prevent air from getting away from the IC or just leave it there?

 

Stock air box had an air pump silencer built into it. That side hose on the stock intake was the outlet from the air pump silencer. It just makes a u-turn down and under the air box.

With the M2 intake the air pump exhaust just returns to the air box and is no longer exhausted through a 7th hose. I guess the idea is to take advantage of the extra flow of air returning from the pump.

You should definetly block off that hole in the IC duct. You want to maximize airflow to the IC.

Did the scoop on your M2 airbox fit down by the fluidine radiator?
I have heard that part of the Mazda Comp radiators side flange has to be cut to make room for the M2 air intake scoop. I am not sure if this applies to a Fluidyne. Can you let me know, as I am still trying to decide which radiator to get.

 

anna: the side hose didn't go anywhere on the stock box, leave off. tape over the IC duct hole. your choice whether to vent BOV or not. Have fun!

 

Thanks for the help guys.

There is no problem fitting the M2 intake in with the Fluidyne radiator. You don't have to cut anything. Good thing too because I forgot to check on that before I put the radiator in.

I have one more question. I am having a really hard time getting the hoses on to the M2 intake. Is there a trick to this that I'm just not getting or do you just have to push REALLY hard?

 

I've got the same setup and it's really hard to get the two large intake hoses onto the intake. On my intake they are just too close together with the stock rubber hoses. I think with just a silicon couplers and the metal intake pipes it would be ok though. I had to cut the very bottom part off the top intake hose lip part in order for the hose to fit over the metal tube and get the clamp on too. Otherwise the doubly thick rubber intake hoses are just too tight of a fit. You might be able to force them on but I could not.

 

a little lube goes a long way too.
