Anyone seen the below or bought one ?  A oil cooler you slip on over your oil filter.  They reckon they have sold 20,000 of them.  Also states the Mo Co sold them out of the HDD catalogue and HD engineers certified a 20 degree temp reduction.  I find that a bit hard to believe but will stand to be corrected.  Its cheap as and if it did work would be well worth the price for 20 degrees drop in temp on a twin cam.  

G'day Jersey, I've got one. Can't measure actual temperature drop, but there is a minor noticeable difference in perceptible heat from the engine with it on and off. The temp drop they talk about is 20 degrees Farenhieght (or however you spell it).


Plus side ... you can save a buck by buying black oil filters

Cheers,

yep, seen them, bought two, they work to a certain extent, not as good as a flow through cooler but for the price and what they do it's worth it.

When fitted to a bike that already has a flow through, you notice a bigger difference.

Link to an older thread on the very subject

I have them on both of my bikes and all my riding mates run them now as well
