The difference between the two model numbers is simply the illumination color. W = white, R = red.
I've always wanted a water temp gauge for this car ever since I decided to take it to the track, however it was hard to find something that modified the car minimally. While I liked the P3 gauge in terms of overall functionality, I wasn't particularly fond of the "AEM wideband" design of it.
This gauge had all the things I wanted: water temp monitoring, oil temp monitoring, and some A/C vent functionality. Additionally, it provides a readout of intake temperature as well. All readings come from the OBD-II diagnostics port.
I ended up ordering it from Japan Parts, who added it to their site:

What's in the box:
I am not going to bore you with details, except to note that for a Japanese market only product, it comes with a surprisingly detailed English instruction that made installation super easy. In fact, it was so detailed it even marked how the tabs are oriented on the vent (that you have to remove), and is about as plug and play as you can get.
(my apologies for the blurry pictures, my tripod is missing)
I will get some impressions of the gauge at a later time, and I also hope to datalog some temperatures. One nice feature is that the digital readouts (oil temp and air temp) has a peak hold function, where you can play back the highest reading recorded since the gauge was last reset. A handy way of making sure your oil temperatures are in check.
While it is possible to get a cheaper gauge setup, for ~$250 + shipping this is about as good as a "factory" gauge can get. The hardest part was making an incision in the vent tube for the wire to pass through, but even that took less than 3 minutes.
