The ER34 oil temperature was running kinda high on prolonged high speed runs and also on enthusiastic driving with constant high revs. An oil cooler kit was one of the top priorities on my to-do list when I got the ER34. I have been clocking about 115 degrees Celsius on my 180km/h runs along the highways (yea speed are still limited until I fix my brakes!) and also on 'enthusiastic' drives along the local hill roads.
Overheated engine oil (which lubricates and cools the engine) has adverse effects as the temperature rises. Its efficiency decreases and breaks down the engine internals. Unless the temperature is properly managed, not only the engine oil breaks down faster, it is also a contributing cause of engine failure/blows.

Pic 3: Errr....ok. I will not use it on the street. :P
I ordered the Trust/GReddy Oil Cooler Kit direct from Japan via air freight and it arrived last Friday. It got detained in Malaysian Customs and I only got to clear it out today. Why a week later? Well I was away from the country in Hatyai, Thailand for a couple of days; and it's the Chinese New Year week for God's Sake!!!
Speaking of Hatyai, boy did I had fun there. Chinese New Year celebration over there was splendid. They had dragon dance and lion dance along the main streets EVERY evening accompanied by deafening firecrackers. Later at night, fireworks lights up the sky. Can't say the same about our dear old Kuala Lumpur. Why is it that I'm beginning to like every other place I go to except where I am now? Sigh.......

Oh darn, SORRY strayed off topic a wee bit....
So ANYWAY, if you are wondering about taxes from Customs, well lets say I got that covered. Hehehehe :)
The Trust/GReddy Oil Cooler helps to maintain the engine oil temperature which is stabilized with high heat dissipation characteristics of the oil cooler design and lower pressure loss. The Kit comes with the below:-

The best part is the steel braided hoses and its fittings. It's from EARL's, EARL'S is the supplier of high-quality military aircraft specification hoses and fittings that supplies to a spectrum of motorsport including F1, F3, A1GP, Indy, Touring Car, British Superbike, Sidecar and World Rally teams. In short, quality motorsports proven stuffs.

The sandwich block has a built in termostat to open/close the valve that leads to the oil cooler depending on temperature. If and when the engine oil is cold, the valve will close and engine oils will NOT flow to the oil cooler. It will re-open only when the temperature rises. Excellent! Wish I had one of those last time when I used to ran an ATF cooler on my previous ride, Project 8110.

The Trust/GReddy Oil Cooler Kit measures 299mm X 185.4mm X 50mm and are mounted right in front of the radiator behind the front bumper. It will sit flush near the drivers side headlights. It has 13 rows as opposed to the other alternative of a 10 rows version. Well I figure 3 more rows would be better isn’t it? Well no harm to be on the extra precaution side eh? :P

I'm expecting my oil temperature to hover around 90 degrees Celsius even on all out hard driving after the installation. Actually I have also considered other alternatives before deciding on this unit. Among them are the HKS Oil Cooler Kit (Part No. 15004-AN008) and ASR Inductive Ceramic Coated Oil Cooler.
But at the end, nothing compares to the Trust/GReddy Oil Cooler Kit. :P
