71k! Might want to change coils while you're in there. Your car will feel like new once you replace both. Wedge suggested the NGK 95770 to me. You can pick up a set on eBay for $66 shipped. I've run them for almost 10k miles and don't have any issues. Per the MHD thread, just remember to gap down to .022".
