So yesterday I got the blinking CEL in my 2000 S2000 with 57k and it felt like I had a misfire so I dropped the car off at the dealer for diagnostics.

Today I got a call that its a coil pack for cyclinder 1, but they don't have any coil packs in stock and want $400-500 for the repair.

I read on here that RSX coil packs are the same as an AP2 S2000 and they will work in my AP1. My question is what year and model RSX coil pack do I need to look for? I figure the RSX plugs will be more readily available. Also should I go ahead and replace the spark plugs since they haven't been replaced before and I'll be down there anyway?

Edit: I think I got the information I need from this thread.
