There are many improvisations you can do. You can make a heat sheild, you can make a little box for the induction kit and seal it in with the air feed....there are many things you CAN do.....its just having the resources to doing them.

Try some simple options first. Give the induction kit another air feed....induction kits should have at LEAST two source of cold air.

If that fails add a heat sheild between the engine and the induction.

If that fails rip that shit off and put ur old air box back on.

Ive had a Pipercross induction air filter fitted for a few months and ive noticed how much more responsive the car is in the evening compared to in the day (im taking it that this is due to the air temperature and that cooler air is making it more responsive). Ive got a air feed pipe coming from the radiator up to the air filter but i was wondering if there is anything else i could do to give a better cold air feed to the air filter??
