Solenoids: are K5T49090 and K5T49091 the exact same part?

Hey everyone, I'm getting codes P2259 and P0661, which pertain to those lovely solenoids behind/under the intake for SSV and the air pump. In shopping around for parts, I found solenoids for some older Proteges and 626s with the model number K5T49090. The ones I pulled from my RX-8 ('05, M/T) are K5T49091. They appear to be the exact same, but I can't tell without testing them side-by-side. That eBay seller seems to think they are, but I wanted to confirm here. The price difference for these new is quite high.



Thanks!
