Yamaha Tracer 7 (21-24) DNA Air Cover Stage 2 and Filter Combo R-Y7N14-S2-COMBO

The DNA Stage 2 Kit, can be either a DNA filter or a DNA cover that is designed to replace a part of the air box, seriously increasing air flow to the engine. With the proper fuel recalibration the results are always very impressive.

Description

Yamaha Air Filter Stage 2
This new Stage 2 Air Box Cover is a CNC machined out of billet black polyamide 6, and designed to work exclusively with the DNA stock replacement air filter. Correctly used it will increase the airflow, torque and power of the engine.
Installation info are included with this new DNA Stage 2 Air Box Cover and fuel injection recalibration is necessary.
The filtering efficiency of the assembly with the DNA Stage1 Air Filter (R-Y7N14-01) is extremely high at 98-99% filtering efficiency (ISO 5011).
The airflow of this new DNA Stage2 Air Box Cover (TC-Y7N14-S2) combined ALWAYS with the DNA Stage 1 Air Filter (R-Y7N14-01) is 179.76% over the YAMAHA stock application!
DNA S1 & S2 air filter flow: 171.30 CFM (Cubic feet per minute) @1,5"H2O corrected @ 25degrees Celsius.
YAMAHA stock paper filter with stock air box cover: 61.23 CFM (Cubic feet per minute) @1,5"H2O corrected @ 25degrees Celsius.
This DNA Stage 2 Air Box Cover is designed for Road and Race use.
This Stage 2 application is developed for race & track use and in some countries it may not be legal to use it on the road.
Fuel recalibration is suggested.

The DNA High Performance Air Filter manufacturing process

Power by quality you can trust!

We, at DNA, proudly introduce a filter that can last the life of the vehicle. Strict quality control for construction & materials, chosen only by their highest quality, are some of the factors that allow us to offer a Lifetime Warranty!

The Anatomy

This is what Power is made of!

A DNA High Performance Filter is a high quality, next generation multilayer cotton gauze, flameproof, oil impregnated air filter.

This very special cotton is designed by DNA's R&D engineers for High Performance filtering purposes. The basic media is a non woven surgical cotton gauze with a modified TEX & THREAD, with extremely high strength of break. This unique cotton media, actually is a “hairy hybrid” featuring extremely high air flow rates and excellent filtering efficiency that exceeds 98%.

FAQs About DNA Filters

The DNA Air Flow Tests

For the air flow tests, we use the most advanced flow bench available today. The ROTRONICS FlowScan, is a totally computerized flow bench that measures:

Mass of the air
Flow of the air
Temperature of the air
Absolute air pressure
Differential air pressure
Speed of the air at various points (Pit ot tubes)
Absolute humidity of the air

The complete procedure is automated and computer controlled, eliminating human errors.

The DNA Dyno Tests

For the Dyno Tests, we use the industry standard Dynojet chassis dyno equipped with eddy current load control, Dynojet 250LC. Our dyno cell is equipped with a variable flow air cooling system, designed to precisely simulate real world conditions.

The DNA Stage 2 Series

The DNA Stage 3 Series

The DNA Stage 3 Kit, consists of a complete air box and filter, designed to replace the existing OEM air box, improve air circulation around the filter and air flow to the engine. Power increase up to 12 HP is common with the S3! The S3 includes all the necessary hardware and installation information.
