Cheapest places to find alternative widebands
Looking for a new 4.2 wideband for my aem unit. has the lever/clamp type connector btw..

Whats the cheapest places you guys know?

I know 4.9 or whatever is the new wideband used now but I got the old one. I might transfer this to my other car and upgrade to the new aem x series but for now I'm just replacing the sensor

Others can post on places to get widebands for other units too.

Lets make this a sticky thread for widebands!

I go to amazon $60

I bought one from fleabay the knockoff $60 ones. It worked ok but I didn't test it against another to see how accurate it was. I sold it off later and put a LSU 4.9 AEM in and liked it so much I changed all of my cars over. Only time will tell if the LSU 4.9 lifespan is what they say it is. But I do know I would only get 1 maybe 2 seasons out of the old ones.

Can we post part numbers too please

and Y2K, did you switch whole units or can we re-pin to use the 4.9 sensors as they are now cheaper than 4.2 sensor?

Autozone, bosh part # 17018.
I believe I paid around $60 with 1 year warranty. So if you sensor goes bad all you do is take it back and you get a new sensor or if you have bad ones laying around you could warranty them as well lol.

once my 4.2 dies, i'm going 4.9. better option imo

4.2 is a waste of time and money these days. And they are not as accurate nor as responsive as the 4.9 units.

Have to change the whole thing. They work totally different from the old school ones. Like nissanegg said wayyy more accurate. If it gets anywhere close to 10+ years use I'll be real happy. I bought my last 2x AEM x300 setups for $179 each and got $120 out of my old ones so it was a easy choice.

I run race gas and m5 methanol on all my cars so my sensors always die prematurely. I can't go wrong with the 1 year warranty lol.

Do you guys think the 4.9 unit will last longer given my circumstances?

Probably depends how much methanol you run. I have heard meth is bad on o2 sensors but that is on the straight meth cars. I have only used gas and up to 66% ethanol on the 4.9 LSU.
