BMP Oil Filter Heat Sink

[markseven]

Is anyone running one of these on their M20? If so, is it a major pain to change the filter with this thing attached?

[kid325e]

I've never seen one.

I've never seen one, but i found it alot easier to remove the filter from the top of the engine. it's right beneath the exhaust manifold.. I dont think you'd really need a heatshield.

He's talking about a heat sink, like to help dissipate heat

Yup.

Linksterino, neighborinos!

Waste of money, you already have an oil cooler. If you need to drop your oil temps... which you most likely wont need to with a stock m20 you can upgrade it with -10 lines and whatever size cooler you want.

[kid325e]

hmm... very informative. thanks. :up:

you install/remove the heat sink before you twist the filter on/off. The heatsink clamps onto the oil filter with the two allen screws

IF you don't tho, such an on an eta, they're a good thing to have. Not that an M20 (i or e) really needs an oil cooler at all anyway, cooling the oil at the filter is good.

i would like to see some data on how much it drops temps... i really doubt its a noticeable difference.

According to the ad in the latest Roundel, it's on sale for $9.99 plus 10% off for CCA members.

We have one on our replica 1929 Mercedes Roadster, and my father in law has almost always used them on his trucks, especially when towing trailers, campers, etc. His oil temps have always been significantly cooler with them than without.

Oil filters get hot as hell. The heat sink is a very simple but very effective device for dissipating heat. They work in all other applications (non-automotive), so it makes sense that they would work on an oil filter. It's the same prinicple as the finned diff covers from an M-coupe.

Mark, for that price, I say get one. Even if it doesn't work, you're only out $10. And if it does work, that's all you paid for it.

^But whose to say the heat sink, which absorbs heat from the filter to pass to the cooler air, won't just absorb head from the much hotter exhaust manifold and leech it back into the oil filter. Since heat always flows to the cooler "stuff."

A heat sink generally absorbs the heat from the object it's in contact with, not the cooler air surrounding it. Even if the air around it is very hot, it is most likely still cooler than the surface that it's mounted to.

Yeah I know how they work. I'm just saying I can't see it being that effective if says its trying to disappate heat into air thats hotter than the heat sink is.

Like the heat sink is 225° but the air around it is 250° because of the exhaust and underhood temps, I can't see it being very effective. Obviously those numbers are made up, but do you get what I'm trying to say?

It just seems like an underhood bling/fuh raze mod to me is all.

Some one should relocate the ambient air temp sensor to see what the temp is in that area.

The idea is simple yet brilliant, and the price is insane. I'll call Bullet tomorrow and ask if we can install it on one of their cars with an oil temp gauge and see if a decrease or increase even registers.

Will order one tomorrow...
