If you have not yet bought a bolt on kit then consider the oil filter cooler collars.

They are "finned" and they slip over the genuine oil filter, either EVOS or twincams

On ebay US for $60 Australian delivered

They drop oil temps 20F , even in stop/go traffic , all for a fraction of the price and none of the headfuck of a plumbed in system

Not the best on computer but tryed to get that page up can not get on to it tryed shearch no luck any ideas thanks

There you go mate

I did have slip on cooler collar 5 years back on my evo for summer but than changed to the ultima down tube type put in line with the oil filter housing lines
and reckon they work better in perth weather ,with the collar you have to use hd oem oil filters two for it to fit ,as it works on interference fit so it wont rattle or
come loose ,as for oil flow evos oil go through the filter after the motor will take a pick later if you need it
