Any part subject to heat damage, corrosion, friction or loss of lubricating film can benefit from coatings. In addition enhanced appearance is possible for parts such as headers, brackets and suspension pieces.
Colors are also available.
This will depend upon many factors that will vary from application to application. Testing has shown significant power increases on a dyno. In addition certain changes can be made in such areas as tolerances, timing, jetting and the lubricants used, that will increase torque and H.P. and are only possible through the use of coatings. Gains of up to 40 horsepower have been measured in independent dyno testing. The dry film lubricants may burnish until they are no longer visible, however the active materials are bonded into the pores of the part and continue to provide protection.
