Super performance filter I put this on my Suzuki GS500 when I did a rejet on the carbs from stock, and it is fabulous when used on this bike. Note, it's ONLY for when you move to bigger jets, otherwise you will just lean out the bike, which is already too lean as is from the factory, and it will not be good for the engine. This unit fits neatly over the carb intakes in place of the air box, which I tossed. It helps improve the performance by allowing more air in along with the extra fuel, and it adds a really nice low growl to the exhaust note, especially with an aftermarket exhaust. Go check out the GS500 Wiki for info on the mod. With Amazon's free shipping, this is the best deal you can get on this product. Much easier than the pods to install, and cooler too IMO....more info
