15k for normal plugs...Iridium plugs can go 90-100K in normal applications. Toyota/Lexus recommends replacing their Iridiums at 120K...I believe GM recommends 100K. For piece of mind, if you have iridium plugs, you could periodically (maybe every 30k) check their gaps and put some anti-sieze on the threads (I wouldn't leave any plug in an aluminum head for 100k without pulling them out at least once and giving them a little anti-sieze).
