i hear peolpe make there own oil coolers? what do you need and how do you install it?

 

its basically a radiator....... except smaller and you know it has the fins and everything..... just have to have some way of recirulating the oil... mine has a fan behind the cooler to suck the hot air out and bring in cool air...... don't bother building one..... pointless.... just buy one

 

I bought one for my 250x and buying the kit is way easier because it comes with everything need.
