The intake air temps are at ambient or within 1 degree (driving at speed). Of course temps rise at a standstill but come back down when driving, as one would expect. It's pretty impressive! I'm enjoying the extra intake noise and I can hear my bypass valve (TurboSmart Plumb Back) too. It's not as loud as a Boomba spacer or TurboSmart Dual Port BOV so it's about perfect.
The picture below is from my drive to work this morning. Ambient temp was 68 degrees, speed was around 55mph. Don't mind the AFR, looks like I was off the gas when I snapped the pic.
