This is a regular 3" long straight coupler for use with high pressure turbo, supercharger, or intercooler piping.

Applications

• Joining your intake pipe to the throttle body assembly, air metering assembly, intercooler, BOV pipe, or turbo inlet/outlet.
• Custom compressor, intercooler or inlet piping for turbo/supercharged car
• Custom cold air intake for nonturbo car
• Replacement of all factory rubber parts
• These silicone parts can be used in trucks, recreational vehicles, boats, or anything else with an engine.

Please note the following when you order silicone parts online. Some vendors have started counting the layers of silicone instead of the layers of reinforcement when talking about the ply. For example, a 3-ply reducer has four layers of silicone plus three layers of reinforcement fabric. Some vendors might incorrectly call this a 4-ply reducer because of the four layers of silicone. All of our silicone parts are now of Genuine 4-Ply construction - that's 5 layers of silicone plus 4 layers of reinforcement for 9 total layers!
