Yeah, that's the price for each one. They're not actually metal though, but they'll work...I'd recommend trimming a bit off of the bottom for better fitment. I also found the 2009+ Mazda RX-8 radio knobs to be much much nicer (and fit better), but they're at least twice as expensive.
yeah, the cost is the only thing holding me back. cant really see the point in spending 30 bucks for a pair of knobs :/ ill prob stock craigslist for wrecked tl's or rx8's and see about getting them cheap.
the thing i dont like about the tl knobs is that it doesnt have a mark on it and i didnt think of that before. not really a big deal but yeah. i wonder what other knobs work... haha
