If your engine is tossing you an oxygen sensor check engine light, replace it with this unit from Bosch. The O2 sensor measures the amount of unburned fuel in the exhaust pipe to adjust fuel mapping for less emissions and better fuel economy. When malfunctioning, your MPG and performance can suffer. Replaced fairly easily, you can restore your performance and mileage quickly. Put some anti seize on the threads to prevent it from becoming a permanent part of the exhaust. Regularly scheduled maintenance as these tend to fail slowly.

The oxygen sensor is part of your BMW's emissions control system and feeds data to BMW engine management computer. The oxygen sensor is positioned in the exhaust pipe and can detect rich and lean mixtures. The goal of the oxygen sensor is to help the engine run as efficiently as possible and also to produce as few emissions as possible. When your BMW oxygen sensor fails, the computer can no longer sense the air/fuel ratio, so it ends up guessing -- resulting in poor performance, poor gas mileage, and increased pollution. Make sure your BMW engine performs as it should, and doesn't use more fuel than it needs to, by simply changing your oxygen sensor today.

A Do-It-Yourself exhaust install can be hard enough. But to stop in the middle of it to run to the dealer for gaskets, hangers, or special hardware is a major inconvenience. Don't be left taking the bus to the dealership on the hunt for parts. Get all of the parts you may need before the job begins! And with mileage we can almost gurantee that any section you remove will need to have new gaskets. Some of the gaskets are crushed to ensure a tight seal; other gaskets become stuck to their flanges. This set of hangers and gaskets for the 2001-2006 E46 M3 covers all of the sections of the exhaust, from the headers to the muffler.

The exhaust on the E46 M3 is broken up into sections -
headers - gaskets at the cylinder head and at the outlet to section 1, plus an air pump gasket
section 1 - crush gasket rings on the inlet and flange gaskets at the outlet to section 2
section 2 - flange gaskets at the inlet and steel exhaust rings at the outlet to the muffler
muffler - steel exhaust rings on the inlet with special square-shouldered nuts (included with hanger/gasket kit)

This package also includes 3 new muffler hangers and the 2 hangers in the center of the exhaust (mounted on section 1).

We also offer most of the exhaust hardware you may need -
Torx bolts and nuts for the header-section 1 connection
copper nuts for the section 1-section 2 connection (M8x30 bolts can be re-used)

Applications:
2001-2006 E46 M3 coupe, convertible

This is a complete exhaust hanger and bracket kit for the 1987-1992 E30 325i models. It's all of the hangers and gaskets needed for the rear muffler and a life-saving addition to any exhaust project on your car. Any of the hardware and hangers that have been on the car for a few years are prone to rust and seizing in place. So to get them off usually means breaking or cutting one or more pieces. So having this complete E30 hanger kit on hand will allow you to finish the job without scrambling for parts later on. And new hangers are always a good idea anyway.

This 325i hanger kit includes -
front upper muffler body clamp - 18201707925 (18211707923) - x 1
front lower muffler body clamps - 18201178132 (18211178126) - x 2
rear lower muffler body clamp - 18211176029 (18211176713) - x 1
rear muffler rubber hangers - 18211712838 - x 2
center muffler rubber hanger - 18211105635 - x 1
muffler to center section seal ring (45mm) - 18111723541 x 1
muffler to center section seal ring (42mm) - 18111245960 x 1
nuts & bolts for all of the above

There is an early and late version to the muffler band clamps but the only difference we saw was more holes in the band on the early style. The early style is included in this kit which might be better because water won't get trapped between the clamp and the muffler body.

If you're removing the center section from the exhaust manifolds you can add those gaskets as well.

This item fits the following BMWs:
1987-1992 E30 BMW 325i 325ic 325is 325ix

Oxygen sensors measure exhaust oxygen. Their signals are used by the vehicle computer to adjust the air/fuel ratio and test vehicle emissions. Degraded oxygen sensors reduce engine performance and fuel efficiency, and increase harmful tailpipe emissions. They can also turn on the Check Engine Light and cause a car to fail an emissions test.
