This is our CNC Aluminum Water Pipe for BMW 335i N55 N54 N53 N52 N51 N20 Engines 11537541992 11537544638

The design and manufacture of this CNC Aluminum Water Pipe is suitable for OEM applications, but its operation is significantly improved. The product is made of high strength aviation aluminum, grade 6061 T6511. Plus, the product is designed to maximize resistance to damage, so you won't break down like OEM accessories. Additionally, coolant flow through the center of the fitting is optimized to maximize coolant flow. There are no sharp corners on this seal, so coolant will not be destroyed when it passes through. Along the same production line, the coolant flow area is 23% larger than OEM parts, further optimizing coolant flow and improving cooling performance.

This product is an OEM replacement for the plastic parts on BMW part numbers 11537541992 and 11537544638. It fits N54, N53, N52 and N51 3.0 liter engines. This BMW part consists of a 25mm (1.0 inch) pipe and a plastic fitting. The hose runs from the coolant thermostat housing to the front of the head. The plastic fitting on this hose is a known weakness in the cooling system because it's usually the go-to solution for cracking and leaking problems is to replace the fitting with a worn, cracked, or leaking one. This accessory can directly replace raw plastic accessories without any modification to any part of the system. Simply remove the end of the hose from the plastic connector, then remove the connector from the head (no need to remove the hose from the thermostat housing). Then install the replacement aluminum connector on the head and slide the pipe and attach the pipe to the fitting. Props are processed from 6061 T6511 billet aluminum (not cast, not forged).

Fits N54 Biturbo 3.0 liter 335i, 335xi, 135i and N53 (3.0 liter atmo) engines from 2006 to 2010 325i, 330i, 525i, 525xi, 528i, 528xi, 530i, 530xi and N20 (2.0 Turbo) Z4 2013- and N52 X3 . This accessory is also suitable for the new generation N55 engines in all frames.

If you are drifting track or just a remapper on your 335i then this is a much desired upgrade as this aluminum coolant accessory will not break under high temperature rail conditions.
