i got mine built with heat resistant silicone tubing. got a Y attachment off of a ferrari with the tubing running down both sides of the motor. its not the aluminum or metal that gets extreamly hot while under the hood. thats just as bad as putting a filter right on the factory airbox exposed by the motor. got it running by the radiator with filters down in front of them behind the bumper. everythings been measured to fit thru all the closest possible space. i'll post pics later. all the silicone tubing with bends and clamps costs 460$, filters were 75$. expensive but worth it.
