I ordered the Rocker cover gasket today for when I do my plugs.
Mitsi charged 17.64 for it. (MD178940) Picked it up and its only for 1 so if you wanted to replace all you need x6
I also ordered the Ralliart air filter from them for $132 + GST
I'll take pics then they arrive.
You really shouldn't be paying more than ¥500 each plus shipping, which is what you can get them from Mitsubishi Japan for. That's around $40 all up to your door with the right supplierNot sure if someone have informed already this but those damn expensive seals are littlebit cheaper at Camskills.

Part number for these is MD327253. I strongly suspect they're a great deal cheaper than this from Japan - I'll look into it.the rubber washers should be changed when you remove the covers, they're $4.20+gst each at mitsi... you need 18 LOL!
Doc, if that plug is iridium.. IMO you got nothing to worry about.. it looks like its doing its job pretty good..
