INTAKE RUBBER RING - Part Number 42-305
Intake Rubber Ring 48mm Spigot seal. Quanity - 1. Ultima Manifold measuring information. To take the guess work out of intake manifold selection, Ultima has devised a way to measure an intake manifold that doesn't require added specialty tools, and best of all, its easy. To determine which intake manifold you need, set the manifold on a flat surface on either of the intake ports, then measure from the flat surface up to the shortest point on the other intake port. Multiply this measurement by 100 to get the intake manifold number. For instance, if the intake manifold is set on the flat surface, and the measuremnet to the shortest point on the opposite port is 2.47, then the intake manifold number you will need is a number 247. It is that easy. Please Note: This system was devised for intake manifold, with port O.D.'s of 1.88 in. Please check the diameter of the intake prots on the manifold you are measuring. If the manifold has a stock O.D. of 1.81 in, subtract .030: from the measurements taken to get the number for the Ultima manifold. For instance, if a manifold with a port O.D. is 1.81 in is measured using the Ultima system, and the measurement comes to 2.59 in, then the Ultima manifold needed will be 2.56 in , or a number 256.
