i saw this thing that looks like a circular piece of metal with padding and ridges that wraps around your oil filter with built in heat sinks like the ones in your computers, it claims to reduce oil temperature. any one see this thing or does it really work?

 

i had one on my 84 Z28, temp did drop a lil bit, plus it was only like 10bucks, so it was worth it, EASY to install, lol. Id get it again

 

But if your that worried about it, you might as well get a oil cooler like a radiator style, they work VERY well, plus if u have an auto they do have combination for oil and tranny

 

i have an external oil cooler on my interceptor. standard civilian oil filter holder that bolts to the engine block is replaced with one that has two hose fittings on it (inlet & return). hoses then run to oil cooler that is located near the radiator.

 

My LT1 has oil cooler lines attached to it, I just need to find the radiator part. My motor came from a Caprice 9C1 Patrol Car.
