Very straight forward installation and it fit about 90% in size and shape (it was a little thicker than it should be but with a little pressure it fit), personally I installed it myself with very basic tools. Don't expect any increase in horsepower from any "free-flow" filter. Its main use is the lifespan and the extra sound it provides! It NEEDS cleaning with special soaps and special oil after being washed at regular service intervals of the motorcycle. (see youtube video or manufacturer's website for instructions)
