Customer Feedback

Definitely better power, transmission stayed in overdrive going up over the Coronado Bay bridge. Before, it would down shift to hold it at 50 mph speed limit. On the first tank now with the New K&N filter, usingTop Tier gas as usual. Nice tight fit in the filter box. Can actually hear the air noise in the intake tube. Had bought a K&N filter for my 2004 Ford E250 at a parts house the same day. (Brand Name) didn't carry the Suzuki filter, that's why I ordered direct...thanks for very fast service. Paul

Great replacement to the factory cabin filter. Easy install ( two minutes ) No more dealer rip off prices. Been dealing with K&N since my days in the motorcycle business ( Suzuki & Yamaha ) in the seventies and eighties on long Island.
