Yes and be careful
Yes the SW is worth it.
You get what you pay for.
Be careful, Vans' SW "STYLE" cooler is not a SW, I am not sure they sell SW.
An "other" brand clone cooler will not cool as good as an SW, ever.**
If you got a fire breathing 360 and you don't live in Alaska get a SW.
If you have a O320 and live in cooler climates you probably get away with another cooler.
One of the other coolers was being deceptive with their data, they just are not as efficient as a SW.
You get what you pay for.
Call (800#) or write Pacific Oil Cooler, they can advise and sell overall all coolers. George RV-4/-7
SW are designed to cool at the pressure and mass airflow we see in our aircraft. Lab test with flows and pressures that are unrealistic give meaningless and useless results. The SW has been proven over in the field over the cheap copies. The copies have improved and be careful or part number. One oil cooler maker has glowing lab reports but does not sell that cooler part #, only the older poor performing unit can be bought. I do not know if that is the case anymore, or if they have sold all their old stock you can may now be able to buy the improved version. Regardless the one liners above apply, best cooling is still with a SW, and it is worth the +$400 cost. I am a cheapskate and I would buy the SW again. Many have not, and end up selling their clone and buying the SW eventually.
