R&D Surge & Blowoff Air Filters Kawasaki Ultra 250X 260X 300X
The R&D Performance Filter Kit features two filters, one for each of the surge and blowoff protections valves. The O.E.M. surge valve recycles compressed hot air back into the air box plenum at idle and under deceleration conditions. The R&D surge and blowoff valve filter kit removes the air recycling hoses which will keep the hot air from entering the air plenum box reducing the engines intake air temperatures. The R&D Ultra 250/260/300X's Air Filter Kit offers great performance tips on how to remove the restrictive air vent hoses which will further reduce the under seat ambient air temperatures. The R&D Filter system does not remove or alter the O.E.M. plenum box in any way, therefore there are no questions to be answered regarding water ingestion!
The R&D Filter Kit is easy to install with no modifications required to the O.E.M. parts. IJSBA legal for all classes.
