I haven't researched it yet, but does anyone use one? It's essentially a magnet that clamps onto the oil filter. At a minimum, I have a magnetic drain plug on all of my cars. Luckily, LSxs have that from the factory.

I use one on my daily driver and after the research I've read, it's good safe insurance, especially with a new engine start up and everyday startup, JMO. I am building a 400 for the 'maro this spring and I will use one from the very first start.

 

if your cheap and buy a poor quality filter, then its a good investment, but using a good quality filter will be just as equal, anything bigger than 25 microns will damage an engine and all the good quality ones will filter a 25 micron particle 99% of the time. and will catch a 5micron particle more than 70% of the time. poor quality ones may catch 5micron particles only 10% of the time.

 

hmm, will a magnet help you attract the lead/AL/babbit chunks of bearings? I'm fairly sure it won't, since I don't *think* those are magnetic
However a cam wiping out, rockers or pushrods failing, etc, those will be held by the magnet.

I think it's worth getting either way, nifty product.

I also thought every SBC has a magnetic drain plug? Isn't that a normal part?

 

Been using one for several years. Can't hurt, might help, so why not.

My RS didn't come with one.

 

Or you can save yourself $35 and tear apart an old harddrive and slap the magnets on your oil filter. Reuse them each filter change. Hard drives use the same neodymium magnets used by filtermag. If you got a few old drives or want to spend a couplebucks at the thrift store, you can get enough for the bottom of your transmission pan too.
