Rosko Racing started offering its services in 2007, specializing in the modification of the Honda H22 CL1 Euro-R Accord Intake Manifold.  Today we offer an entire selection of parts for the Honda Euro-R and H series engines.  Nearly all of our products were born at the race track with an idea, then designed and tested by us prior to offering it for sale.  We believe in real world testing and have partnered with some of the fastest H series cars in the sport to continue to develop and improve our products.  All of our products are 100% manufactured in house at our facility located in Des Moines, IA and sold through our exclusive partner Kaizenspeed/KSTuned.
