R34 Pod Filter

[GTSBoy]

Your car must be tuned right on the edge then, surely. I mean the air flow meter is a heat element, it takes temperature into account when it calculates air density, so any heat soak you are getting from the pod shouldn't cause knock, it will just mean less power.

It's not the density so much. It's just that hot air makes ping happen more readily. Yes his car is possibly tuned a bit close to the edge.....but the question is always how far away from the edge you want to be, and if you even know where the edge is in the first place.
