BMW 1 Series E87 Adaptor Fitting for Thermostat Plugs, Aluminum

Upgrade your BMW’s cooling and intake reliability with this Aluminum Adaptor Fitting for Thermostat Plugs, designed to fit a wide range of diesel engines. CNC machined from a single aluminum billet, this adaptor delivers a precise, durable connection that helps reduce inlet air temperatures and keeps the inlet and turbo cleaner, helping to maintain performance and responsiveness you feel on every drive.

This adaptor is a versatile fit for many BMW models, including the 1 Series E87, 3 Series E90/E91/E91N/E92/E93, 5 Series E60/E60N/E61, 7 Series E65/E66, X5 E70, X6 E71, and X3 E83/E83N. It’s designed for diesel engines (not petrol) and is intended to replace faulty parts rather than the entire system, making it a cost-effective upgrade or repair option. Note that it is specifically listed for diesel BMW engines such as M47, M47N, M57, M47N2, M67, and M47R variants and for related E46 318d to 330d configurations in diesel form.
