” BMW’s hot hatch, the M135i, gets a new aftermarket program from the German specialists over at TuningWerk. TuningWerk’s engineers are mostly about performance, so don’t expect any flamboyant body parts. Their BMW M135i however, outputs 90 hp more than the standard version of the hatchback. The 3.0-liter inline 6-cylinder engine of the TuningWerk BMW M135i develops 450 PS (331 kW) thanks to a re-mapped ECU, a modified turbocharger, a larger intercooler, and an additional water cooler. TuningWerk also equipped their M135i Bimmer with a custom Puchheim exhaust system with a down pipe with 200 cells cat, and a dual mass flywheel that’s 2 kg lighter than the factory one. Optionally, TuningWerk can equip your M135i with a single mass flywheel that’s 4.5 kg lighter. More power from the engine means more stress and the clutch. TuningWerk swaps the BMW M135i’s standard clutch with a reinforced one. ”
