Not the manifold, but the intake valves. This may or may not be an issue many miles down the road. Some believe all direct engine engines eventually require the valves to be cleaned as they never are in contact with gasoline as in port unjection. Walnut shell blasting is considered the best method. Somewhat expensive however. Around $500.Since this is GDI engine, do I need to clean intake manifold like other GDI engine cars?
I can't find any maintenance schedule for intake cleaning, in fact there's no clear maintenance schedule for the car, it just says to read display for any maintenance reminder..
This subject doesn’t get much interest in Honda forums. Maybe not a concern. Others should weigh-in.
