Temps, cleaning radiators, and spoiler

Back in the spring I got the Dashcommand app and the Elm 327 OBD2 wifi transmitter, so I started monitoring a few different parameters. One of the first things I noticed was that with the spoiler up, intake air temps would be 3-6 degrees cooler than with it down. The next thing I noticed was that coolant temps were reaching 223. Ouch! ( although they seemed a degree or so lower with the spoiler up) I knew I needed to pull the bumper cover and clean the radiators. Got it done this weekend...and also opened up the fender liners so the radiators would exhaust into the wheelwells along with under the car. Today was the hottest day this summer, and it looks like the effort paid off. The highest temp I saw today was 207, and on the highway, where temps used to run 210-215, today it was right around 199. Two other bits I noticed: it took much longer for temps to climb to operating and highest, plus things cooled off much quicker. Cool!
