Installation was rather easy. Instructions we're a bit vague. Camshaft vacuum hose was tight to fit into polyurethane body. I found it easier to put gasket on hose first then insert into housing. Hose clamp to hold housing to bracket was too small, bought a 4.5 inch hose clamp, worked fine. All in all so increase in low range Power by about 5 to 7. Had seen 0 to 60 not much increase, does work well when they paired it up with brand new ignition wires and sparks from NGK. Good product easy to install if basic knowledge of car maintenance is known. Hardware was quality mostly stainless steel and fit exactly into OEM bolts and housing holes. Could make instructions a PDF or possibly do a video, instructions are vague.
