On a related note, if I do ever get around to fitting my ToyoSports exhaust manifold, I'll have a go at creating a heat shield with his stuff ... m-x-1000mm

It probably won't impact the air intake temp but it might help the o/s engine mount and the steering uj

I think there's a reason for that panel behind the grille, something to do with forcing air through the radiator or keeping it away from the engine to control temperature difference across the block, something like that. If you drive a 231, you've already got a cold air intake in the form of the VFAD in the nose, not sure what the 192 has though since I've never seen one.

You could go with the Racing Beat duct like Dave suggests, or the AEM intake sits in the same position. The VFAD draws air from the same inherent location as those two anyway - there's a gap in that plastic panel, right below your number plate. That's where the intake draws air from, just not quite so directly.
That is correct. The panel in the grill is to block airflow towards the engine as it would cool the front of the engine excessively relative to the rear.

What about methanol injection? Probably OTA on NA's. Wouldn't that reduce intake temps?

yes it would but it also adds a fair bit of fuel so you need an ECU re-calibration to make it work or fit an aftermarket ECU so its not trivial

My IAT's run +2 degrees above ambient most of the time, they only rise to +15C or more when in stationary city traffic.

I fitted a wrapped tubular manifold and an AEM copy intake running a custom K&N cone filter. It's also been mapped by Carl so the fan temps are reduced too. If I insulated the intake I could probably get IAT to ambient most of the time.

The standard airbox sits above the rad, its a big thermal mass so getting the temps down will be really difficult. That said, and AEM intake will only work properly after MAF scaling with ME or Versatuner
Have a good time, all the time :thumright:
