Direct injection engines are great for power and fuel efficiency! However, they do have a substantial drawback. Without the benefit of fuel being sprayed on the backside of the intake valves, like a traditional port injected engine, carbon buildup becomes a big problem!
Because of this inherent issue, manufacturers recommend having your intake valves cleaned every 30,000 to 60,000 miles!!
Your vehicle will experience a lack of power and reduced fuel economy, due to the restriction this causes. The good news is, Valley Auto Pros can help!
