No-Weld O2 Sensor Mount: AEM 30-2355-250 2.5" - Easy Installation Solution Review

AMAZING product. I was actually looking for details to make this thing with my own hands when I found out it was already created. For the same price I bought this, used a step drill and installed it in about 30 minutes. Fill the old hole by driving in the failed O2 sensor and covering it with high temp epoxy. FABULOUS!

Very high quality and a real pain in the neck. At least for me. I used a Neiko 10194A titanium step drill to drill through the whole thing and then spent the remaining 58 minutes of the hour trying to get my fat hand under the turbine to hold all the pieces together and tighten. The part is great, my struggle was a fat man with short arms trying to install the part without scratching the paint.

I originally purchased a glowshift mount that was bent in such a way that it was causing leaks and consequently inaccurate AFR readings. The seal doesn't hold well at all, maybe it's a dirty pipe, I don't know. It was also a bit flimsy but I managed to put it on and everything was fine once the clasp was tightened. You need to make sure the hole you drill fits the flange on the bracket or it won't clamp properly.

As with most cheap aftermarket parts I was very skeptical, especially one that wraps around the exhaust pipe and doesn't leak. I have to say this isn't a crappy piece you would buy in a car shop, it's made out of very thick metal, way heavier than your exhaust pipes. I wouldn't hesitate to buy it again should the need arise. One thing you should do is buy stainless steel nuts and bolts.

I was skeptical at first but a friend came along and we used one on his exhaust to install broadband and after that I was sold. Instead of taking my test tube off and taking it to weld the connector on, I was able to buy a step drill and drill a hole, install it, and then install the O2 sensor for the broadband sensor. I've had it for about 3 months, no leaks or any issues. If you don't want to or can't fit a weld plug, this is the way to go.

I always have problems with welding next to me. Everyone does a bad job and looks like a mess when they weld, so I decided to do it myself. This set is simple and straightforward. You'll need a step drill up to 7/8" in diameter to get the job done properly. The hole has an inner stepped edge where it fits into the hole you drilled and seals it with a gasket. fully. It took me about 30 minutes in total and I'm very happy with the clean install.
