Thank you for choosing COMP Cams® products; we are proud to be your manufacturer of choice. Please read
this instruction sheet carefully before beginning installation, and also take a moment to review the included

The COMP Cams® Acura/Honda B-Series VTEC valve spring set (Fig.
A) utilizes dual springs on the intake side and a single spring on the
exhaust side. Below are the information and diagrams to ensure correct
installation.
Installation Instructions:
Warnings and maintenance information!
It is important to orientate the outer valve spring of the intake and
exhaust (See Fig. B & C) with the *tightly wound coils on the
bottom. THE ORIENTATION OF THE INNER INTAKE SPRING
IS NOT CRITICAL.
*Note: To figure out which end is the tightly wound end start at
the end of the coil. Follow it around 180° (See Fig. D) then look
at the distance between the two coils. Now follow the same steps
from the other end of the spring. Whichever end is closest
together needs to be on the bottom.
