Sort the intercooler first, then the piping, or buy both together and do it as one job.\u003c\/p\u003e\n\n\u003cp\u003eThat's different from PRL's 11th gen kit, which works with either.

Keeping that section tighter maintains velocity where the turbo needs it, so you get the flow gains without giving up spool.\u003c\/p\u003e\n\n\u003ch4\u003eWhy Factory Piping Costs You\u003c\/h4\u003e\n\n\u003cp\u003eTwo separate problems with the stock arrangement.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDiameter.\u003c\/strong\u003e A 1.5\" path restricts flow, and that restriction becomes the limiting factor once you've added an intercooler with real capacity.

That gets worse as boost increases and worse again as the rubber ages and weakens, eventually becoming a leak.\u003c\/p\u003e\n\n\u003cp\u003eAluminum doesn't expand and 4-ply silicone handles heat and pressure considerably better than the rubber it replaces.\u003c\/p\u003e\n\n\u003ch4\u003eSilicone Where It Matters\u003c\/h4\u003e\n\n\u003cp\u003eCustom molded 4-ply silicone couplers throughout, for three reasons.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHeat transfer.\u003c\/strong\u003e Silicone conducts heat far less readily than metal, so it doesn't pull engine bay heat into charge air you just cooled.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eFlow through bends.\u003c\/strong\u003e Molded silicone allows smoother, tighter radius bends than metal tubing can achieve in the same space.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eMovement.\u003c\/strong\u003e The engine moves and the chassis doesn't.
