APR IC100005 Front Mount Intercooler Kit (FMIC) for 2000-2001 Audi B5 A4 1.8T

Achtuning is pleased to present the APR IC100005 front mounted intercooler for the 00-01 B5 A4 1.8T. The construction and advanced design techniques used in the APR intercooler sets theirs apart from all the others on the market. Utilizing such technologies as a top-bottom feed core, custom mandrel bent plumbing, and innovative cast endtanks with internal vaning, the APR intercooler has produced excellent results in testing.

The conditions of one test that was performed were as follows: at 20 psi of pressure with a vehicle speed of 70 mph, and an elevation of approximately 500 feet above sea level. Under these conditions the internal flow was measured at 720cfm. Also at those conditions, with an input temp of 240º F, the intercooler was quite effective; cooling the output air to 126º F. While doing this, the intercooler measured an internal pressure drop of only .58 psi.

Equally as impressive with the APR intercooler was the external pressure drop (the amount of air pressure behind the intercooler) of only 1.01 psi. This helps to allow airflow to other critical parts of the car such as the radiator and A/C condenser. While the internal pressure drop is important, the external pressure drop is often overlooked. Most other intercoolers commonly cause 1.5 to 2.0 pounds of pressure drop, hindering the radiator from effectively doing its job of cooling the engine.

The highlights of the APR IC00005 FMIC kits include the following:

• APR Cast End Tanks with Internal Vaning
• Top-Bottom Feed Bar and Plate Aluminum Core
• Mandrel-Bent, Powdercoated Stainless Steel Plumbing
• APR Custom Silicone Intake Hoses
• All Associated Brackets and Hardware

APRs Front Mounted Intercooler Kits were developed specifically with the 1.8T engine in mind. Extensive research went into to choosing the proper sized heat exchanger and what the optimal flow direction would be. A top-bottom, bar and plate heat exchanger with proprietary internal heat sink fins was chosen. This style heat exchanger offered very competitive performance when compared to the more an extruded tube design. Along with a low internal pressure drop, this style heat exchanger excels by presenting a lower external pressure drop then an extruded tube design. This allows for more air to penetrate through it for cooling of the radiator and other essential components.

Once the ideal heat exchanger was chosen, the task of using it to its fullest potential began. Unique cast aluminum end tanks were designed to ensure that the hot air entering the system would travel the full length of the core. A precise fin structure within the end tank helps to distribute hot air evenly across the core for the most effective cooling possible. Each fin is positioned at a specific angle to direct the correct amount of air down into that section of the heat exchanger. This allows the whole core to work at dissipating the heat.

When moving this air to and from the intercooler, you want to do so with the least amount of resistance as possible. With this in mind an effective series of tubing was designed. A combination of stainless steel and silicone tubing was used to create seamless internal geometry for the air to flow through. The stainless sections are used for the longer spans of tubing. The silicone is used to seamlessly and smoothly transition between diameters and to navigate through existing hardware.

APRs FMIC kit would not be complete without quality mounting hardware. Careful attention was paid to this area. We found that custom sheet metal designed brackets offered a healthy balance of a strength and aesthetics. All sheet metal parts are powder-coated to withstand rust so that they will remain strong throughout the life of the product.

Note:
Due to the large size of this intercooler an S4 or RS4 front bumper is recommended, a front spoiler such as a Votex or Kerscher may work as well.
