would it be advisable to get a steel sump/trans plug rather than an aluminium one? as don't 2 items of the same metal have a possibility of bonding together I've heard?

also, does the S2000 have magnetic plugs as standard or not? as I was thinking of getting some if it doesn't

"new owner, hence basic questions, finding things out"

 

Beware of cheap magnetic plugs, the magnets have been known to fall out over time. No they do not come with magnetic drain plugs from the factory.

 

cheers. Tegiwa (UK) who sell on here have some for sale. At £13 ish I'd not say they were cheap?

I'd assume collecting metal particles from the oil is better than not doing, but as you said it doesn't break! . I used to have one as standard on my old Rover Mini back in the 90s. Cars since haven't had them.

 

I just checked out tegiwaimports website- they seem to be the uk version of password jdm. They have some nice items. I can't say for certain if they are quality or not because I have never heard of them but based on some of the stuff they make, they seem to be a legit company.

I have been running the spoon magnetic engine/transmission plugs for about four years now with no issues.

 

If you want a cheap magnet(sometimes free), go to a computer repair store and get the magnet's out of a 600 gb on up hard drive. Rip them out and stick them on your oil filter.

Actual, the trouble with types of metals comes with 2 DISSIMILAR types. Not that it bonds together or anything, but it creates more corrosion. Either way, I'd hope you would be removing and replacing these plugs FAR before any of this happens.

 

Only an issue if you have a large difference in galvanic corrosion electrode potential.

 

To your original question. You are correct in that like materials may bind. The specific process for this type of interactions called "galling". If both materials are the same (specifically hardness) then this may occur. In this case the pan is a casting and the plug is machined from bar stock. Thus they likely have very different hardness(with the pan being less dense and softer). By the way this is why it is so easy to strip out a drain pan hole, always use a torque wrench. Screwing a steel lug into
Aluminum is not advised. Dissimilar metals are adversely affected by a processs known as galvanic corrosion (Google can give you the specifics of these noted processes). Honda engineering did not incorporate a magnetic plug on the engine as the filtering capabilities of the filter remove any particulates in question. The only exception to this being a severely clogged filter. This condition could result in the filter bypass opening (to prevent the filter from over pressurizing and failing). Moral here is to change your filter. Honda did install a magnetic lug in the differential as there is a potential for high micron metallics in that system

That is exactly what I did but pulled the magnets out of old HDD's I had on hand from years ago. They are amazingly strong!!! Careful putting it on a stainless steel fridge as it might scratch trying to pry it off.
