An ally inlet tube absorbs the heat and warms the air going in

I am going to wrap the one we have on the ZS (came with the car).

Bet it gets more heat from passing through the valves in the head.
Air is moving fast enough..........

Can`t see a problem with it tbh

Why heat the induction air? Am I missing something? To get more power you need cold air to make it denser, think inter cooler as it cools the intake air to give more power. Tbh with these engines the only way of getting any real increase is to supercharge them

Good luck

That engine looks really good

Yep, colder the air charge the denser it is, denser the air more fuel you can add, more fuel and air equals bigger bang and more power. Simple.

Hence why turbo charged engines employ an inter cooler as compressing the air makes it hot and less dense even though it's compressed. By Cooling that pressurised air you get more weight of air in same volume.
