The APR MS100127 Coolant Performance System (CPS) for the Audi 3.0 TFSI and 4.0T TFSI engines increases engine reliability and HP consistency by controlling intake air temperature with a completely re-engineered performance cooling system. The APR CPS is a massive front-mounted heat exchanger that dramatically reduces intake air temperature, minimizes heat soak, and provides increased performance! It is 140% larger than stock and features a self-bleeding cooling circuit to ensure it is always operating at peak performance. The system is easy to maintain and fully integrated into the factory cooling circuit. This upgrade is highly recommended at every stage!

APR MS100127 Front Mount Coolant Radiator:

Properly functioning air-to-water intercoolers rely heavily on the temperature of coolant flowing through the system. Increasing the volume of coolant and increasing the surface area of front mounted radiators significantly reduces coolant temperature. With an increased volume of coolant, coolant takes longer to warm and with an increased surface area, coolant temperature is reduced at a more rapid rate. The APR Heat Exchanger towers over the 5.5 inch tall OEM unit and stands over 17 inches tall in comparison. This massive increase in size results in 140% increase in coolant capacity!


APR MS100127 Testing:

Utilizing a B8 S4 3.0T at APR Stage II+ Ultra power levels, six back-to-back dyno pulls were conducted with minimal cooldown time between runs.

Using the APR CPS system, horsepower remained consistent for the first four back-to-back dyno pulls. By the fifth back-to-back pull, horsepower dropped slightly when the IAT protection threshold was crossed. The IAT threshold triggers a bypass of boost pressure to cool off the system and protect the engine.

The factory heat exchanger did not fare well. Horsepower losses began on the very first pull and the IAT threshold was crossed by the end of the first dyno pull. This trend continued dramatically, resulting in massive power losses to protect the engine from excessive intake air temperature. The factory cooling system simply did not stand a chance. On the 6th run peak horsepower dropped to as low as 260 AWHP, whereas the APR cooling system retained over 400 AWHP, even after the sixth consecutive back-to-back pull!

Pass on this expensive heat exchanger

I ultimately settled on this APR heat exchanger because of the self bleeding system. The problem is, the self bleeding components are metal and they install over the top coolant port which is plastic. The plastic port is easily broken, mine cracked resulting in a leak. Now I'm stuck replacing the entire radiator. APR: please update your instructions on step 41, when installing the brass coolant tap fitting, use EXTREME caution when tightening as the force needed to install this part is far greater than the plastic port can handle. Mine cracked with half the threads still showing on the brass tap. APR's tech support confirmed this has happened to others, so I felt compelled to write a review. Also I want to mention once the self bleeding components are installed, it puts the hardline hoses in an awkward bind since the tap extends out about 2 inches further than original and the hardline hoses can't just be cut to remove the slack. This is one of the most expensive systems available for the 3.0. Only black and white photos are available for the install and the self bleeding system is more trouble than it's worth.

We would love to hear your feedback on this product
