Due to a past mishap with a Jeep that wiped out the '05 sedan with the DE engine and that the '08 I replaced it with has the HR I've ended up with the following brand-new items that may do someone a
bit of good:

Six (6) NGK Iridium LFR5AIX-11 plugs
Motordyne 5/16" plenum spacer kit (complete) even comes with the decal
Motordyne lower plenum thermal gasket
ECCP (aftermarket) valve cover set (L&R) even has all the gaskets already in place. The reviews on these were pretty good and as a pair of OEM valve covers was $720, I figured they were
worth a shot.
I've got a bit over $500 not including tax and shipping in all this but I'll sell it all for $300 + shipping.
