What It Does & How It Helps

The intercooler, or charge-air, boots and couplers carry pressurized turbocharged air between the turbo, intercooler and intake. Heat, oil mist and boost pressure eventually crack them or blow them off, and the resulting boost leak shows up as sluggish power, extra smoke and sometimes a check-engine light. Fresh silicone or OE-spec boots with new clamps restore a sealed charge-air path and full boost, bringing back throttle response and fuel economy.
