What catch can size???

[BoroBoroS13]

So im about to order a Cusco catch can and they come in two sizes, 9mm and 15mm. Which one is closest to the CA18 size? Thanks

I would get whatever is cheapest. A catch can isn't exactly a complicated, high tolerance device. I could build one with a coffe can and some JB weld if I really felt like it...

I'm guessing the sizes are for the hose connections.. if you're going to the big valvecover hoses then the 15mm is probably closer in size to that.. but you're best bet would be to measure the inside diameter of the hose you're using

It is the valve cover hoses, thanks.
