The R&D high performance Air Filter Kit will improve acceleration and top
speed performance by increasing air flow and reducing air temperatures
that enter directly into the Ultra 250X's air plenum box area. The O.E.M. air
plenum box on the Ultra 250X is a great design that will flow plenty of air.
However, the air that feeds the plenum box is heated by the engine. R&D has
created an easy to install "flat filter" that installs directly in place of the large
center access inspection cover located directly under the main glove box.
The R&D Flat Air Filter insert will allow unrestricted fresh and cool air
to enter the air plenum box area which will add power you can feel and
a nice high performance tone. The R&D Performance Filter Kit also 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 250X 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.

RIVA ULTRA 250X PRO-SERIES
POWER FILTER KIT
Ultra 250X Pro-Series Power Filter Kit is a race-bred air intake system that
draws cool air from outside your engine compartment delivering awesome
performance and eliminating power-robbing heat intake. Air enters the
system under the glove box area through an oversized K&N air filter that is
protected by a composite cover to prevent water intrusion. Air is fed to the
supercharger via a large 4" diameter intake duct. Ducting is precision
formed from a race proven composite that will not conduct heat into
incoming air. Includes replacement glove box tray & water-repellent pre-filter.
Not stock legal with IJSBA or APBA.
