You don't want a warm air intake on a diesel. As long as you can keep your intake manifold temperatures above 30'F to 40'F its all good.
You don't want warm fuel unless you can heat it to about 300'F. There was a study posted on here that showed fuel economy and power dropped off as fuel was heated, until it hit 300'F.
The only time warm air and warmed fuel will help you is winter cold starts. Besides that your injectors are burried inside the cylinder head, the fuel gets plenty hot before it gets injected when the engine is warm. You dont want too hot of fuel going to that expensive CP3 injector pump.
What I think is don't try gas engine eco mods on a diesel and loose that muffler and run the shortest possible straight pipe you can get away with.
