Managing under-bonnet temperatures is a top priority on the turbocharged B58 engine, especially when utilizing aftermarket tuning to increase boost pressure on your M340i. Drop your intake air charge temperatures and protect internal components by installing high-performance Chargecoolers paired with durable, smooth-flowing Boost Pipes. Keep your engine oil and coolant temperatures strictly regulated during continuous hard runs with high-efficiency Radiators and standalone Oil Coolers. To stop oily crankcase mist from re-entering your intake tract and forming power-robbing carbon deposits, fit one of our premium Oil Catch Cans.
