Fine-Media Walnut Blasting With Angled Tubes for Spark-Plug-Hole Access
The WD816 blasts 0.4โ0.6 mm walnut media through 23 intake adapters or eight angled tubes while a filter screen and HEPA stage recover media and carbon. Combustion-chamber cleaning through the spark plug hole is only for vehicles whose procedure allows it; an external compressor is required.

Good to Know
Caution
- An external compressor is required. Supply dry, filtered air through suitable hoses and fittings with enough duty cycle; walnut media is also needed unless your order lists it.
- Use combustion-chamber, intake or exhaust access only when the vehicle procedure names the access point and method. Tube reach alone does not make a job suitable.
- Recover all visible media before starting the engine.
- Wear eye, hand and respiratory protection, ventilate the work area and follow the media SDS.
Care
- Reuse recovered media only when both the manual and the vehicle procedure permit; use fresh media whenever either requires it.
- Confirm the 110 V or 220 V nameplate before connecting power.
