n54/n55 intake valve cleaning. With fuel direct injected engines carbon and oil builds up on the intake valves, causing misfires, lowering your car mpg, and robing the engine of its power and decrease in overall efficiency. Fix your rough idle issue, restore lost power to your n54/n55 engine, and feel the difference of increased acceleration. Its a night and day difference. I use a two step process by manually cleaning the intake valves and using walnuts to get a superior cleaning. Walnuts are completely safe and is the preferred method when cleaning intake valves. The process takes about 2-3 hours.Please contact me if you have any questions. Located in metro Detroit! I'm not a business or a business entity just an enthusiast helping other enthusiast!
