Chemically resistant inserts and/or spacers for an intake manifold that enable flow of coolant fluid and kits having the same

An intake for an internal combustion engine comprising:

• a main body having a first set of runners extending in a first direction therefrom and a second set of runners extending in an opposite direction therefrom, wherein both the first set of runners and the second set of runners each terminate at a back end with a flange that defines a socket configured to receive an insert;
• a coolant crossover juxtaposed to and attached or integral with the main body, wherein the coolant crossover has a first end more proximate the first set of runners and a second end more proximate the second set of runners,
• a first interface spacer attached to the first end of the coolant crossover;
• and
• a second interface spacer attached to the second end of the coolant crossover, wherein the first interface spacer and second interface spacer are each made of a material that is chemically resistant to coolant fluid;
• wherein the first interface spacer defines a through-port and has a top surface defining a first perimeter recess about the through-port configured to receive a first sealing member and a bottom surface defining a second perimeter recess about the through-port configured to receive a second sealing member;
• wherein the second interface spacer defines dual through-ports and has a top surface defining a third perimeter recess about and between the dual through-ports configured to receive a third sealing member and a bottom surface defining a fourth perimeter recess that about and between the dual through-ports configured to receive a fourth sealing member.

A kit comprising:

• a first insert configured as a port cap or as an insert having a hollow, elongate spout extending from a tip surface thereof, wherein a bottom surface of either defines a first perimeter recess configured to receive a first sealing member;
• a second insert configured as a port cap and having a bottom surface defining a second perimeter recess configured to receive a second sealing member;
• an intake manifold comprising a main body having a first set of runners extending in a first direction therefrom and a second set of runners extending in an opposite direction therefrom, wherein both the first set of runners and the second set of runners each terminate at a back end with a flange that defines a socket configured to receive one of the first and second inserts, respectively;
• wherein the first insert and the second insert are made of a material that is chemically resistant to coolant fluid;
• a first spacer attachable to a first end of a coolant crossover;
• and
• a second spacer attachable to the second end of the coolant crossover, wherein the first interface spacer and second interface spacer are each made of a material that is chemically resistant to coolant fluid;
• wherein the first spacer defines a through-port and has a top surface defining a third perimeter recess about the through-port configured to receive a third sealing member and a bottom surface defining a fourth perimeter recess about the through-port configured to receive a fourth sealing member;
• wherein the second spacer defines dual through-ports and has a top surface defining a fifth perimeter recess about and between the dual through-ports configured to receive a fifth scaling member and a bottom surface defining a sixth perimeter recess that about and between the dual through-ports configured to receive a sixth sealing member;
• wherein the first insert and the second insert are made of a material that is chemically resistant to coolant fluid;
• optionally, the coolant crossover.
