The Dinan system includes a cold air box. The cone filter is in the box keeping the engine heat away from the intake tube. The system increases the volume and velocity of incoming air. Dinan printed gains have always been conservative. The 4.4 gain is 13HP and 12TQ. The 4.6 is 14HP and 11TQ. To reach these numbers you need the matched engine software which further increases performance gains as do the Dinan MAF and throttle body if you can find them. With the above components plus the free flow exhaust the total gain on the 4.4 is from 282HP to 321. The torque increases from 335 to 350. The 4.6 from 340 to 369 and 371 to 382.
