Everyone forgot about the pumping loss reduction from WAI. Warmer air = thinner and easier to compress. It also reduces the effective compression of the engine because there's just less air being pumped in, meaning less force on the piston required to reach TDC on compression, so less bearing/ring friction, etc.
