Ignition Coil You can't tell much about a distributor cap or rotor by just looking at it, because most of them look pretty much the same on the outside. Even so, there can be significant differences in the materials used in the manufacture of distributor caps that affect the product's performance on a vehicle. One competitor's cap is made of materials that do not even meet OE specifications. The competitor's cap is made of PP (polypropylene) which has a much lower melting point (350¦F) than the materia l in which our caps are made from and they are made from incorrect molds. Because of this, the competitor's cap had a slightly smaller inside diameter, creating potential fit problems as well potential melting/warpage problems. Our caps exceed the OEM s pecifications and are made from a blend of PBT (polybutylene terephthalate) and PET (polyethylene terephthalate). This material has a higher melting point (500 degrees F) and also provides increased stiffness and resistance to warpage. You'll find that the same strict quality standards that make are Distributor caps the finest in the industry apply to our point sets and condensers.
