Sprint Filter: the C-Tech Kit for the Mercedes A 45 AMG, CLA 45 AMG, GLA 45 AMG
Since conceiving its C-Tech range, Sprint Filter has always focused on sports cars with the highest power ratio, which explains its decision to work on the Mercedes AMG A45S. The M139 engine, as mounted on the Merce-des A 45 AMG, CLA 45 AMG and GLA 45 AMG, develops 387 hp but can achieve as much as421 hp at 6750 rpm and500 Nmof torque in its more powerful S version, which also boasts one of the highest specific power values of all, at 211 hp/liter.
Significant increase in performance
Taking such a high-performance engine, in which no detail has been left to chance by AMG, the Sprint Filter R&D Department has been able to achieve a significant increase in performance without making any modifications to the vehicle’s hardware or software. The product stands out for the fact it can be assembled in a matter of minutes and is made entirely of carbon, the fibre of which is the best available on the market, processed exclusively in the autoclave. The kit comprises an air box with inlet, split into two half-shells that contain an air filter designed specifically for this kit, a particularly high resistance sleeve (6 PLY) and a support for the repositioning of the control unit, which affords better cooling of the electronic unit. Once the Sprint Filter C-Tech Kit is installed, the maximum engine power and maximum engine torque of the strictly standard Mercedes A45S AMG is boosted from 417.0 hp at 6721 rpm and 488.7 Nm at 5068 rpm to 424.9 hp at 6830 rpm and 496.9 Nm at 4620 rpm. The high-pressure fuel pump demonstrates a Duty Cycle increase of between 2% and 3%, with a maximum peak of 4%, thanks to the greater demand for fuel resulting from the higher charge pressure. This increase in charge pressure can be generated by boosting air intake capacity with a more permeable air filter and the regularization of intake air flow owing to the design of the new Sprint Filter C-Tech air box.
