Properly Vented hood, period!
I havent had a chance to track yet but around town driving fast, 90* stop and go traffic for hours, canyon carving etc! I've yet to hit 220 in my 13. I don't think the coolant increases temps because coolant stays around 200-210. That's obviously cooler than 270. But if you want to remove the OEM one you need the oil filter threaded plug off a 09-11. I just bought one from nissan. It's only $8.
Also SSfirehawk?? Had a 72 row
. He's in Vegas and I believe had trouble hitting 200.
