Tall lambda sensor weld-in boss (M18 x 1.5mm Stainless)

Description

This is an extra tall, finned stainless steel lambda/oxygen/wideband boss designed primarily for welding in to individual headers or exhaust manifold runners. The taller boss helps to keep the sensor cooler by keeping the majority of the probe out of the runner. It also helps gas flow by not occluding the runner any more than is necessary. See the picture below for suggested fitting.

M18 x 1.5mm thread to accept the common Bosch wideband sensor and most other lambda sensors. 25mm wide x 21mm tall. They are 20mm high.



Standard low profile bosses available – see “Sensors & Leads” category.
