Honda F engine
From Wikipedia, the free encyclopedia
The Honda F-Series engine was Honda's "big block" SOHC inline four, though lower production DOHC versions of the F-series were built. It features an aluminum open deck cast iron sleeved block and aluminum/magnesium cylinder head. Honda's F22B1 Engine won a spot on the Ward's 10 Best Engines List in 1995 and 1996.
