I am currently stuck between two choices. I might get a GODSPEED intercooler that needs custom piping or a Koyo s5 radiator. I searched on da google and the forums but didn't find a clear answer. Will the s5 koyo radiator fit in my s4 with ease or is it just not possible?

 

you will need the s4 brackets. why not just use the s4 koyo? it doesnt have the long filler neck on it.

 

intercoolers are radiators are not the same thing.

just get an S4 koyo and call it a day.

 

Because the radiator is slightly used out of a s5 and I can get it for cheap. What's wrong with a long filler neck? Can I use the s4 barckets from my stock radiator?

I'm aware that they aren't the same thing it's just a choice.
