i see the price difference but whats the difference in looks/performance? thanks

 

type 24 is taller.

 

I thought the number referred to the length of the core...the 24 is 24" and the 31 is 31".

 

 

I would also like to see, im in the works of buying an intercooler for a 91 civic dx, plus I thaught that the type 31 came with piping or no?? plus the type 31 is H 186mm L 600mm x 149mm. I dont know the dimensions for the type 24.

 

24 is definately larger.
