sorry I didn't reply to this sooner.

i never said that the product would hurt, just that I don't really see if being that beneficial. there is so little iron and steel in our engines, I don't see this thing doing what the oil filter can't.

now see, I've owned a car with an iron block before, and that is definitely an application where i could see using one of these plugs being beneficial. occasionally when I changed the oil in that car I'd see iron filings stuck to the drain plug (apparently it was slightly magnetic) about a 1/4th the size of the kind you'd see when you explain magnets in high school science class.

but seeing as how most of our engines are aluminum, I don't think these magnets are going to pick up very much-definitely nothing scraped off the engine block.

I guess if they catch stuff they are working. They seem really pricey though!
I am pretty sure Napa carries universal ones that would fit for a lot less.

IMHO the magnets would apply more in the transmission(s) and differentials than in an aluminum engine. Steel gears grind a lot more than an engine at its internals would.
My BMW motorcycle has a magnetic drainplug on the final drive, from the factory, for good reason as the gears are under great stress when riding offroad. I sometimes find a very fine powder on it when changing the oil.
I will get them for my tranny and diffs where applicable..

My 01 H6 has a big magnet in the oil pan stock. You cannot see it unless you remove the oil pan. I think most subaru's do as well. Part number for the magnet is 31392AA030. Looks like Subaru has been using magnets in the oil pan since atleast 94.

Maybe the next thing will be the gas line ionizers! "Put these wonderful magnet thingies on your fuel line and ionize your gasoline for better performance. Only $19.99 plus shipping and handling!"

Is this what you are talking about: Transform Fuel for Increased Fuel Efficiency and Maximum Performance - Fitch Fuel Catalyst? It Looks like the price went way up.
