Cool Air Filter Kit.
Now available for the 250X $116.95
This was designed to help provide cool air to the stock air intake. If you have ever seen the inside of a stock air box then you already know it is hollow and has no obstruction in it. In its designing it offers one of the safest ways to obtain air and lots of it. This kit enables cool air to come from under the glove box area for those choosing not to change out the stock air intake systems.
From R&D:
R&D ULTRA HIGH PERFORMANCE AIR FILTER KITPT# 215-25000
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 250’s air plenum box area. The O.E.M. air plenum box on the Ultra 250 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 protection 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 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.
-
Improved low end performance
-
Great high performance tone
-
Cooler engine air temperatures
-
Cooler engine compartment temperatures
-
Easy to install bolt on performance (no modifications)
-
Low cost performance advantages
Ive installed a few of these now and find them to be a great addition to help lower engine compartment temperatures. Though you do have to unbolts the side and center cowling to enable the flat filer to slip into place, the install is easy and fast.

R&D seems to be stepping it up with what they are bringing to market. They just updated their site with a whole bunch of goodies… injectors, sponsons, fuel stuff, supercharger stuff etc. I am sure you probably already know most of this.
Take care. Keep doing what ya doing. Thumbs up.

Yep, have had a many of long phone calls with them. Told ya alot was comming just took longer then expected.
Have a riva intake in the hull. wouldn’t this help w/ this since intake filter under glove box? water injestion issues?
water injestion would be my only concern. We will have to wait until Skip can find time to do some testing with the Riva unit. He also has the R-Rated intake which sits much further forward in the hull and will probably not be an issue with this mod since it is further forward and not right under the glove box like the Riva unit.
Just my thoughts.
Bingo, this mod is NOT recommended with any Riva intake. Riva unit does indeed sit right under this. The volume of air comming into that intake would easily suck water through the Outerwear material. I have not tested in this combination but simply looking at it was enough for me to not want to try it.
Im not sure. I am learning towards NO it not but that is only my interpretation of the rules.
Is this set of cool air kit race legal for the stock class ?
