The oxygen sensor or O2 sensor is a fundamental part of your engine that is located in the exhaust manifold. They are tasked to monitor how much unburned oxygen is available in the exhaust as it exits the engine. This is in order to gauge the fuel mixture and inform the engine computer if it is burning rich or lean. For the installation or removal of your O2 sensors or vacuum switches, Mr. Gasket offers their Oxygen Sensor Sockets to properly get the job done.

These wrenches integrate an efficient offset "crowsfoot" blueprint which lets users easily access typically harder to reach areas. This blueprint bestows the extra leverage needed for a hassle-free removal as the featured cutaway side produces the ideal sensor wire clearance. Manufactured using premium-quality materials, the Mr. Gasket Oxygen Sensor Sockets are another essential component to be added to your toolbox. For the optimal performance of your oxygen sensor, Mr. Gasket also offers a selection of weld-in oxygen sensor bungs.

Mr. Gasket Inc. is a world-renowned manufacturer of high-performance aftermarket parts. Mr. Gasket was founded in 1964 by the famous drag racer Joseph Hrudka to become the go-to supplier of aftermarket race-approved exhaust gaskets. However, before officially founding the company, Hrudka investigated and developed durable asbestos gaskets to replace the faulty exhaust gaskets that were a major problem for many racers. He sold these parts under the Speed Specialties name in the 1960s before incorporating his company as Mr. Gasket in 1965. From selling high-performance Gaskets in the '60s, Mr. Gasket has become well-known for a wide range of premium products, including but not limited to billet aluminum dress-up components, valve covers, air cleaners, master cylinder covers, shifter knobs, pedals, and ignition wire looms. While the ownership of the company has changed hands several times, Mr. Gasket has withstood the test of time and is still an industry-leading supplier of high-performance aftermarket parts.
