Hi

Need to replace the oil drain plug on my 1997 Boxster ...... What Size is the Plug?

thanks!

Get the LN Egnineerng magnetic replacement.

Ive looked at the LN one and the magnet doesnt look all that large.....

I was considering this one with a XL magnet, what do you think?

Its the one last on the list

and I think the correct size is m18-1.50 on the boxster

The magnet may not look very large but it has very strong flux density - far stronger than your average magnetic plug....

Ummmmmmmmm......this is one time where "size does not matter." What you should be concerned about is how strong the magnet is, rather than how large. And the LN unit is very strong.........

I would also think that since the magnetic rod sticks up alot higher it would also catch more metal in the oil ........ maybe I am wrong?

Up to a point, you do not want the plug to protrude up so high it gets in the way of things. A strong enough magnet exerts its field out into the oil without having to stick up further, gets the job done without being in the way. One of the most common ways to pick up metal in the oil is to surround the filter with a very strong magnet, so nothing is actually protruding into the oil, but rather the oil flows over a magnetized surface, but this gets expensive:

Is the filter cover metal on the boxster? couldnt one just stick a strong magnet to the outside of it if so??

It would be if you also purchased LN's billet spin on filter adapter, instead of the cheap plastic/paper OEM one.

I have both the adapter and the LN drain plug on my car with excellent results. I can also assure you, the LN plug is very powerful.

I can second this & I also use a "FilterMag" on my rebuilt engine. I keep an extra drain plug here in O.C. CA if you are local.

How is the magnet connected to the actual drain plug on the LN? Glue or weld or ??? ...... what happens if it loses its charge and come loose from the plug?
