Ever get the feeling that the car seems to have more power on a cool night? With the 9N Polo GTI Intercooler kit, you can enjoy this feeling all the time. Cooler air is denser, which contains more oxygen molecules to burn when compared with warmer air. This kit will help to prevent the “heaksoak” effect of smaller intercoolers.
 
The kit is designed to fit directly on the Polo GTI. It comprises of an APR Intercooler core, alloy piping, silicone pipe sleeves, securing brackets, hose clamps and bolts. The Intercooler fits nicely behind the centre grill of the bumper – in fact, none of the bumper’s plastic requires any cutting at all. This allows maximum air flow from the front of the car to lower the intake temperature, ultimately increasing performance of the car. The construction and advanced design techniques used in the APR intercooler sets ours 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, our intercooler has produced excellent results in testing.
 
The conditions of one test that was performed is 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 a 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 Intercooler kit include the following:

• APR Cast End Tanks with Internal Vaning
• Top-Bottom Feed Extruded Aluminum Core
• Mandrel-Bent, brushed alloy plumbing
• Custom Silicone Intake Hoses
• All Associated Bracketry and Hardware
