AP Design S55 Silicone Charge Pipes / Boost Pipes Kit for BMW M2 Competition F87, M3/M4 F80 F82 - Intercooler Hoses & Turbo Outlet Pipe Upgrade, 5-Ply, Billet Adaptors | F8X Charge/Boost Hose Replacement

Upgrade Your S55 Boost Plumbing For Power, Reliability And Flow

Raising boost on your BMW M2 Competition, M3 or M4 and want rock-solid reliability with maximum airflow? This AP Design 5-ply silicone boost pipe kit replaces the fragile factory plastic ducting that is known to split under load. The smooth round internal profile promotes excellent flow for rapid turbo response and consistent performance on road, track and strip.

Why this boost pipe kit is the go-to choice

• 5-ply silicone construction built for tuned S55 engines. Ideal for remapped and high-boost applications.
• CNC machined billet 6061 aluminium turbo outlet adaptors for a precise, leak-free seal to the turbochargers.
• Lower heat absorption than alloy hard pipes which helps reduce heat soak and maintain charge air density.
• Smooth, round tubing for less restriction and maximum airflow through the intercooler system.
• Easy servicing. Unclamp at the intercooler and fold out of the way for quick access to ignition coils and spark plugs. No need to disconnect from the turbos.
• All hardware included. Supplied with liner-style hose clamps designed for soft silicone to protect the hoses and maintain clamping force.
• Proven durability with extensive testing on our shop M2 Competition that holds the European quarter-mile record.
• Backed by a 2-year warranty for confidence on the street and the circuit.

We run this kit ourselves and customer feedback has been outstanding. Tuned S55 owners report a noticeable improvement in reliability, consistent boost, and peace of mind compared to the OEM plastic charge ducting.
