Features Our 90 intake kit features our patented Big Sucker™ ″hidden breather″ technology and more filter surface area than any other kit we know of on the market for maximum performance. Ness hidden breathers are o-ringed at the heads and exist out the mouth of the injector/carb to provide efficient engine breathing, eliminating the need for any external hoses or hardware. The inverted 90 degree style filter features a built-in inverted top to pull in air not only from all sides of the filter but also the front, which results in a higher performance gaining airflow. Each filter is constructed from synthetic material that is water resistant, which in most cases eliminates the need for a rain sock. Filters are re-usable and do not require oil, just rinse and re
