Stage 2 Air Box Cover Design

This DNA Stage 2 kit replaces the stock air box intake cover on compatible Royal Enfield Hunter 350 models. It eliminates the OEM intake snorkel and provides a higher-flow intake setup.

Moreover, the kit uses DNA’s advanced FCd design and a high-quality EVA seal. The EVA seal helps provide airtight sealing during installation. When combined with the DNA Stage 1 air filter, the Stage 2 cover delivers the specified airflow increase.

Airflow Performance

The DNA Stage 2 kit works together with the DNA Stage 1 air filter R-RE35N21-01. According to the supplied airflow data, this combination provides 99.48% more airflow than the OEM air filter with the Royal Enfield air box cover.

The DNA S2 and S1 combination delivers 1917 LTR/MIN at 10 mBar corrected at 25°C. In comparison, the stock air box with the stock cover and OEM air filter delivers 961 LTR/MIN under the same test conditions.

Therefore, the Stage 2 setup provides a significant increase in measured airflow over the standard configuration.

DNA Stage 1 Compatibility

This Stage 2 kit works with the DNA Stage 1 Air Filter R-RE35N21-01, which is sold separately. For the specified airflow results, you should use the Stage 2 cover together with this DNA Stage 1 filter.

The combined setup is designed to increase airflow, filtering efficiency, power, torque, and throttle response. However, the supplied product information recommends fuel recalibration for this Stage 2 setup.

Race Use Application

The DNA Air Box Cover Stage 2 for Hunter 350 (22-24) is designed specifically as a High Flow product for race use only. Therefore, it is intended for applications where increased intake airflow is required.

Furthermore, the Stage 2 kit provides a different intake setup by removing the OEM intake snorkel. This design also offers a higher-performance intake configuration and better intake sound, according to the supplied product information.

Easy and Secure Installation

The kit includes a cover and uses a high-quality EVA seal for installation. This seal helps create airtight sealing between the Stage 2 cover and the air box.

In addition, the installation replaces the stock plastic air box intake cover. The Stage 2 cover should always work with the specified DNA Stage 1 air filter for the stated airflow configuration.

Important Compatibility Information

The Stage 2 kit must be combined with the DNA Stage 1 Air Filter R-RE35N21-01, which is sold separately. The supplied airflow figures apply to the combined DNA S1 and S2 setup.

Note: This DNA Stage 2 kit is designed for race use only, and fuel recalibration is suggested
