Kibblewhite 20-4322 Engine Exhaust / Intake Valve Kit

We choose to use C630 nickel bronze as a material to make valve guides because of its ideal characteristics for the application. The 4-5 percent nickel content provides superior resistance to wear, and the approximately 80 percent copper content delivers outstanding heat conductivity. Guide profiles are designed to have minimal effect on the airstream while maintaining critical cross sectional thickness in high temperature areas, promoting high performance and endurance.This item fits the following models: 1994-2004 Harley Davidson FLHR Road King1998-2004 Harley Davidson FLHRCI Road King Classic1996-1997 Harley Davidson FLHRI Road King2000-2004 Harley Davidson FLHRI Road King2004 Harley Davidson FLHRS Road King Custom2004 Harley Davidson FLHRSI Road King Custom1987-1993 Harley Davidson FLHS Electra Glide Sport1986-1987 Harley Davidson FLHT Electra Glide Standard1995-2004 Harley Davidson FLHT Electra Glide Standard1984-2004 Harley Davidson FLHTC Electra Glide Classic1996-2004 Harley Davidson FLHTCI Electra Glide Classic1989-1997 Harley Davidson FLHTCU Electra Glide Ultra Classic1995-2004 Harley Davidson FLHTCUI Electra Glide Ultra Classic2003-2004 Harley Davidson FLHTI Electra Glide Standard1986-1990 Harley Davidson FLST Heritage Softail1988-2004 Harley Davidson FLSTC Heritage Softail Classic2001-2004 Harley Davidson FLSTCI Heritage Softail Classic1990-2004 Harley Davidson FLSTF Fat Boy2001-2004 Harley Davidson FLSTFI Fat Boy1993 Harley Davidson FLSTN Heritage Softail Nostalgia1994-1996 Harley Davidson FLSTN Heritage Softail Special1997-2000 Harley Davidson FLSTS Heritage Springer
