Designed to eliminate the OEM intake snorkel on Royal Enfield models, this performance upgrade delivers dramatically increased airflow, improved throttle response, and a more pronounced intake sound. When combined with the DNA Stage 1 Air Filter (R-RE35N21-01), this Stage 2 cover transforms the air intake system for both road and race use.

The system flows +99.48% more air than the stock setup and is manufactured using multi-layer surgical-grade cotton gauze and epoxy-coated aluminium mesh. Designed to last the life of your vehicle, it requires minimal maintenance and is backed by DNA’s lifetime warranty. For best results, always use in combination with the Stage 1 filter (sold separately).
