happy Saturday everyone...it's been a week since I've driven the Z, my ankle is still kinda iffy and I'm waiting on the dimple oil plug to get here so I can do my oil change...does anyone use these dimple magnet oil plugs? I'm wondering if it's common practice to change these every oil change since they're $35 each...People rave about them in the DIY Oil thread.
EDIT: after reading their website more thoroughly this might be somewhat of a stupid question
