Why Walnut Blasting for BMW?
Direct-injection BMW engines (N20, N26, N54, N55, B58, S55 and more) can build carbon on intake valves. Walnut blasting removes those deposits without harsh chemicals or metal tools, restoring:
-
Smooth idle and throttle response
-
Power and fuel economy
-
Reduced misfires and cold-start stumble
-
Lower emissions and longer component life
Signs You Need Walnut Blasting
-
Rough idle, hesitation, or loss of power
-
Reduced MPG and sluggish acceleration
-
Misfire codes, especially at startup
-
Intake valve inspection shows heavy carbon

Walnut Shell Blasting FAQ
1) What is walnut shell blasting on a BMW?
It’s a specialized cleaning of intake valves/ports using crushed walnut media to remove carbon on direct-injection engines without damaging metal surfaces.
2) How often should I do it?
Most BMW DI engines benefit around 80k–120k km. Tuned cars, short-trip driving, or heavy city use may need it sooner.
3) What are the benefits I’ll notice?
Smoother idle, better throttle response, restored power, improved fuel economy, and fewer misfires.
4) Is it safe for my engine?
Yes—done correctly with ports sealed and borescoped, walnut media won’t harm metal. We document before/after photos for peace of mind.
5) Do EVs need walnut blasting?
No—EVs have no intake valves. We still service EV brakes, tires, suspension, alignments, and inspections with EV-safe procedures.
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.
