I'm out of town right now, but I can pull out the OBD and get you a temp reading in a few days.

To be honest, I just walked in O'Reilly and got the biggest one that would fit right onto the MAF. I wouldn't see there being much area difference between the cone and the pod, but I don't actually know the numbers.

Ok, I just took some temp readings. It's 66 degrees outside according to the built in thermometer. Going down the 4 lane at 60 the intake temp was 74.2 degrees. At idle it climbed quite a lot (past 110), but once you got moving it went right back down pretty quick.

Can't wait to see if those angled spacer works. Please post back once you find out.

Nope. The headers stop before the cats. You need to whip up some custom exhaust with O2 bungs fore and aft of the cats.

18mm. They can be found on eBay by searching "90 degree O2 spacer"
