Build your K-swapped EF chassis with the Hasport EFK5 Performance Engine Mount Kit, designed for installing a Honda K-series engine into the 1988–1991 Honda Civic and CRX. The EFK5 configuration is specifically designed for use with 2008–2013 Accord, 2009–2014 TSX, and 2012–2015 Civic Si manual transmissions.
