Perodua Bezza Carbon — Port Injection
1KR-VE and NR-VE: both port injection — zero intake valve carbon. No walnut blast ever needed. Simple combustion system, easy to keep clean with regular oil changes.
Bezza Carbon Buildup
- City stop-go driving causes throttle body and intake carbon — throttle cleaning every 30,000 km
- Grab Bezza: throttle clean more often due to constant city idling
- Occasional highway driving (>30 minutes) helps burn off carbon
