If you want a larger can from Mishimoto, roll your own with the baffled OCC like the one I use. Purchase a PCV hose from Rock auto and get some 5/8" ID reinforced tubing. I purchased clear, stainless steel reinforced tube, but its not necessary. It helps me see at a glance how well the system is working. Here are some pics of the can, installed on the passenger's strut housing. I drilled and tapped a 7mm x 1 hole and using a fastener and the supplied bracket from Mishi, attached it to my FiST. Works great, much bigger that the plug and play. All you need to do is take an exacto blade, score each connector on the PCV hose, pull each connector off, then using a good quality hose clamp, attach it to your 5/8" ID hose. Then attach the other end of the hose to the OCC. Couldn't be easier.
You can remove the bronze filter if you are concerned about it, in the winter. I live in So Cal so we don't have winters.
This can is bigger than a coke can. Here is my 5000 mile pour from the OCC:
Here is a pic of the can on my work bench to give you an idea of how big this can is.
Mishimoto's OCCs are overdesigned, and made of quality materials. I should know, I'm a metallurgical engineer so materials and processing are my forte. The other cans fall short in comparison.
