11537541992 Water Hose Fitting Replacement For BMW 335i N52 N53 N54 330i Aluminum Racing Car Parts 11537544638

Description:

Aluminum coolant fitting is designed and manufactured to precise tolerances to fit the OEM application with notable improvements in function.

Machined from billet aluminum 6061 T6511 (not cast, not forged).

Designed to maximize the resistance to breakage, so that it will not fail as the OEM fitting does.

The coolant flow path through the center of the fitting is optimized to maximize coolant flow.

There are no sharp corners on this fitting so that the coolant will not be disrupted as it passes through.

Along this same line, the surface area of the coolant flow path is 23% larger than the OEM pieces which further optimizes coolant flow, improving cooling performance.

Direct replacement, no modification.
