The high-quality and extremely robust core used in this intercooler offers excellent cooling properties, delivering strong performance even under unfavourable conditions. It combines high resistance with outstanding heat dissipation, meaning it does not heat up as much as comparable products from other manufacturers. Alongside the cast aluminium end tanks developed using 3D CAD, the minimal pressure loss makes this intercooler an essential upgrade for any vehicle.<\/p>\n<h3>Technical details<\/h3>\n<ul>\n<li>HF-Series core dimensions: 540 x 280 x 100 mm (OEM: 640 x 160 x 80 mm)<\/li>\n<li>58% greater charge-air volume: HF-Series: 8.7 l (OEM: 5.5 l)<\/li>\n<li>84% greater core volume: HF-Series: 15.12 l (OEM: 8.23 l)<\/li>\n<li>Surface: black powder-coated<\/li>\n<\/ul>\n<p><strong>Road use:<\/strong> A parts certificate for registering the modification is included. This intercooler has also been tested in combination with the open E-Intake V2 and the HJS downpipe, as stated in the certificate. The certificate also confirms compatibility with ECE-approved exhaust systems and a replacement catalytic converter from another manufacturer carrying ECE 103R approval. When fitted, the properties of these components must be shown to remain equivalent to the standard components by means of a stationary noise measurement.<\/p>\n<h3>Product benefits<\/h3>\n<ol>\n<li><strong>Improved flow and even pressure distribution for maximum efficiency<\/strong><\/li>\n<li><strong>Cooler charge air:<\/strong> temperature measurement of HFS compared with OEM showed a difference of -46\u00b0C (OEM: 88.53\u00b0C \/ HF-Series: 42.48\u00b0C). Thermal test HFS vs OEM.<\/li>\n<li><strong>Earlier response and improved performance<\/strong><\/li>\n<\/ol>\n<h3>What does an upgraded intercooler provide?<\/h3>\n<p>To express the exact power increase provided by an intercooler in figures, many unknown factors must be taken into account, including factory power variation, other hardware changes and the software used during testing. Results vary from vehicle to vehicle. As a rule of thumb for tuned engines, an increase of up to 5\u201310% can be expected.<\/p>\n<p>At least equally important is the fact that, at high ambient temperatures, an upgraded intercooler prevents a loss of performance or even activation of the temperature protection stored in many control units. This allows you to rely on the full engine performance, whether the engine has already been software-tuned or is to remain standard.<\/p>\n<h3>Recommendation<\/h3>\n<p>We recommend using our HF-Series intercoolers as part of a combination of hardware and software optimisation. Reducing back pressure, which relieves the turbocharger, and cooling the charge air, which increases the oxygen content in the combustion chamber and reduces thermal load, creates a performance upgrade that efficiently uses the potential of any turbocharged engine.<\/p>\n<p>When modifying a vehicle\u2019s hardware or software, boost pressure loss must not be overlooked. If vehicle power is increased through chip tuning, boost pressure is also increased in 99% of cases. With the standard intercooler in place, boost pressure loss rises exponentially. The turbocharger must therefore work harder, increasing its thermal load and reducing its service life; higher rotational speeds also accelerate wear. Our HF-Series intercoolers create the ideal balance between cooling performance and boost pressure loss.<\/p>\n<p><strong>Suitable for:<\/strong> Audi RS3 III (8V) \/ IV (8Y), Audi Ttrs II (8S).<\/p>\n<h3>Manufacturer\u2019s vehicle data<\/h3>\n<ul>\n<li>HF-Series Front-Ladeluftk\u00fchler Audi RS3 8V \/ 8Y, TTRS 8S 2.5 TFSI 367\/400PS<\/li>\n<\/ul>\n<p><em>Original product name by HG Motorsport (\u00bbz.B.\u00ab = e.g.).
