SL55/63/65/R230 AMG: My new Mars RED SL55 | lowered with Radenergie R10 | PICS




here is an assortment that would have you covered for $9

edit ... looking at the picture a little more closely, I'm going to guess again and say it looks to be 1/4 NPT ... your local speed shop should have these (hanging on the wall next to their aluminum AN fittings)

considering the "heft" of this HE ... steel or brass seems in order.
I would go for a flush style plug (allen or square-drive ... 2 plugs on left in pic)

one more idea for your H E drain/plug .
if you have the flexibility in your mounting area relative to the vendor installed mounting tabs (or you are removing the mounting tabs and welding on more application-specific tabs like I am) ... you should consider mounting your HE with the drain bung UP (see pic I shot yesterday right before I removed the "Tabs"). this way the bottom of your HE is clean AND you can use the hole to bleed out the air on your initial fill of the system.

on second thought (what was I thinking?) i would source aluminum plugs (both the 1/4 NPT for the drain AND the 1/8 NPTfor the temp sensor bung) AND I would recommend aluminum hose-barbs. Steel is not so good here and .... Brass and aluminum together in a cooling system can (will) lead to aggressive Galvanic Corrosion issues. It would be a shame to bugger up the IC (mounted under the supercharger) due to saving a few bucks on fittings.

Now need to find a good upholstery shop to swap the boots.

But if you dont want the inlays, you could put a dab of chrome on your grill. Like the 3-fin you showed us with the chrome slits, EXCEPT- make the silver part black.... IMO- the car would be finished..
