Why It's Important
Direct injection engines like the THP200 are prone to intake valve carbon build-up. Unlike port-injection systems, fuel no longer washes over the valves—allowing deposits to form, restricting airflow, and impairing combustion.
Common issues caused by carbon build-up:
❌ Misfires / EML light
❌ Power loss and sluggish throttle
❌ Poor fuel economy
❌ Rough idle and starting issues
The WBA + Enigma Solution
Our adapter makes it easy to perform Walnut Blasting—a modern cleaning method using finely crushed walnut shells to gently remove carbon without damaging aluminium internals. No need to remove the cylinder head or use harsh chemicals. Results in:
✅ Restored throttle response
✅ Increased volumetric efficiency
✅ Smoother idle and start-up
✅ Optimised fuel use and performance
