Walnut Shell Blasting FAQ
1) What does walnut blasting fix?
It removes hard carbon from intake valves that causes rough idle, misfires, power loss, and poor fuel economy.
2) How long does the service take?
Most jobs are completed same day, depending on model and access.
3) Will this help my fuel economy and power?
Yes. Restored airflow improves throttle response, idle quality, MPG, and overall performance.
4) Do Electric Vehicles need walnut blasting?
No. EVs don’t build intake valve carbon, but we service EV brakes, tires, suspension, and inspections.
5) What else should I do while we’re in there?
Fresh intake gaskets, PCV service, and new spark plugs (if due) are smart value-adds during blasting.
Why is Walnut Shell Blasting Necessary for DIT Engines?
In direct injection engines, fuel is sprayed directly into the combustion chamber rather than over the intake valves.
As a result, the intake valves are not regularly cleaned by fuel, leading to the accumulation of carbon deposits over time.
This carbon buildup can restrict airflow, disrupt fuel-air mixture, and negatively impact engine performance.
