Just got my R18B in time for the off season! I’ve been reading through to learn about all the mods and upgrades available in an effort to plan for the post-first-service fun. So far, Brentune is a likely winner. Where I’m stuck is around the DNA filter/frame job. I’m no engineer, so my understanding is based on what sense I can make out of real world users’ experience vs the company’s claims and marketing. I get more air means more fuel means more power. Cool.
I’ve seen recorded gains in other vehicles (cars and bikes) of between a fraction of a percent up to maybe 2% gains in HP and torque when using just a cotton/oil filter (k&n or similar) and no other adjustments. These were used in stock airboxes where other mechanical restrictions are built in. While small, a gain is a gain and at the cost, over the life of the vehicle, probably a bit of a win for the reusable filter. The oft-cited issue is that the cotton filters present risks to both particle bypass issues and sensor failures due to oil collection. Not sure how prevalent these issues are in a mid-western climate, but understood - there’s risk.
My wondering here then is, what if we did a hybrid version using the OEM paper filter for max particle collection, but use the DNA frame to open up the airbox and max out airflow. In my head, you get the best of both sides with keeping clean and drawing more air. What’s the catch? Anyone with more sense than me have thoughts here?
