Re: HOW TO: TB (Throttle Body) Cleaning (WITH PICS!!!)
Man after seeing that throttle body, I gotta wonder what sort of internal damage the K&N is doing to these engines. I have 40,000miles on my 3.5L and it looked a lot like your finished product without having been cleaned. I will never use anything other than a dry air filter on any of my vehicles. The small amount of particles that pass a dry filter are far less then the amount of dirty filter oil that gets sucked through. K&N may look and sound good but other than that it's a complete money waster.
