WALNUT BLASTING IN WAIRAU, AUCKLAND

At Wairau Motors, we offer walnut blasting as a specialist service to remove carbon build-up from engine intake systems on both petrol and diesel vehicles, helping engines breathe properly again.
Our Approach to Walnut Blasting
Modern engines are prone to carbon build-up over time, particularly vehicles used for short trips or stop-start driving. This build-up can restrict airflow, reduce performance, and cause rough running.
Our mechanics take a careful, methodical approach to walnut blasting. The intake system is properly prepared, carbon deposits are safely removed using crushed walnut shells, and the engine is reassembled correctly to manufacturer standards.
This process cleans effectively without damaging engine components.
