Greddy magnetic oil drain plug
 

Is this really useful? Juan is selling it for 16$ on his website.

I have had one since I bought my FD. Previous owner had installed it. Every time I change my oil it collects a fair amount of gunk. It used to collect more, but since I installed a FilterMAG, it's quite a bit less.

Personally, I would spend the money on a FilterMAG before the drain plug. Very strong Earth magnet, and more surface area. Rx7.com has a nice blurb about it, and it's where I got mine. Makes the little drain plug seem kind of useless when you clamp this bad boy on.

If you need a new drain plug I guess it can't hurt to purchase. What I've often wondered was why people use magnetic drain plugs when the oil goes through the oil filter before entering the engine. :lol: With that said, I also have one of those FilterMAGs, though it was given to me haha.

Here's a diagram of the rotary engines oil flow. This isn't an REW but the oil flow is similar.

Those magnets are STRONG! I usually do that girly move where you kind of throw it at the filter so I don't pinch my fingers lol.

Must be true, it's from THE FUTURE!

Marty, we're gonna need more plutonium!

As far as on topic, I don't know if either option will necessarily help anything. It definitely won't hurt. But, is that magnet going to save apex seals? Or a water seal? No. This would be something to get when you have everything else 100%.

I've seen too many FD's where owners spend money on silly things and miss the basics.
