Great Gains

We took this 100% stock S4, baselined it and then added the full @aprllc parts catalog including dual pullies, cooling kit, intake and ultracharger. We also added a southbend clutch, new OEM flywheel, 034 engine mounts, new plugs and coil packs amongst other maintenance items. The results are astounding, the before/after graph looks like it is 2 different vehicles. We’re talking over 150WHP/130WTQ gains from the baseline!! While we love throwing mods and HP at cars as much as the next person, it’s critical to do the proper maintenance at the same time to avoid potential catastrophe.
