OE and Aftermarket Stock and Performance Parts for the Briggs Model 40/44/49 Intek V-Twin Engine. We commonly find these as race engines for B/P and FXT Racing Mowers. We have led the way for performance parts and have advanced mower racing to new levels of speed and competition. The Intek is for those that believe there is no replacement for displacement. The Intek is the largest stock displacement Briggs engine in what we call the small block V-Twins.
