Amount of time required to bolt on: 30 minutes.

A free-flowing inlet tract is part two of the inlet-airflow equation. We selected JLT Performance's ram-air intake system (PN RAI-FMG-9604; $175) for Ivan's stocker. The ram-air kit includes everything you see in this photo (clamps, silicone reducers, removable S&B Powerstack filter) and a plastic heat shield that isn't shown. Unlike most CAI heat shields, JLT's isn't fully enclosed and thus blocks the filter from radiant heat only at low speed and idle. We ordered Gloss Black to match the color of our test 'Stang's exterior, but JLT's ram-air tubes can be ordered in almost any body color.

This huge, 4-inch JLT inlet is the heart and soul of JLT's ram-air intake kit. It's the largest air-inlet tube for Two-Valve engines that we know of, and since the pipe is made of plastic, it has a much greater resistance to heat-soak than similar metal inlets.

With the factory air-inlet system (air box/filter and tube) removed, Saul uses the mass air adapter to connect the 'Stang's original 80mm mass air to the ram-air tube.

The system also accepts much larger 90mm (Cobra/ Lightning) mass air meters.

The inclusion of this JLT Ram Air Intake system netted us four more rear-wheel horses and four extra lb-ft of torque. Keep in mind: torque is represented as a seat-of-the-pants/driving-experience sensation. With the gains we're recording from each bolt-on, we're fairly sure Ivan will immediately notice a difference in the way his 'Stang accelerates. Amount of time required to bolt on: 30 minutes.
