Have you lost performance? Hesitation on take off?
Try our walnut blast cleaning service!
Walnut blasting is the most effective method of cleaning intake valves and intake ports. Vehicles using direct injection engines will build up carbon deposits over time, directly effecting throttle response and oil consumption with the potential to cause unwanted vibrations. Carbonized intake valves lead to bumpy idling and all around poor performance. Walnut blasting fixes dirty intake problems.
Chemical cleans do not work on this engines as there is not enough time to absorb and breakdown the different deposits. Hydrogen cleaning will not do anything to the carbon on the intake valves as the reaction in this cleaning process only starts in the combustion chamber.
