Amazon O2 Sensor Review: Gledwen vs. Bosch LSU 4.9 for AEM X-Series
HTML-код
- Опубликовано: 8 сен 2024
- I didn't expect much from the Gledwen replacement O2 sensor I ordered on Amazon, but it pleasantly surprised me with its performance. I'm always on the lookout for cost-effective parts, and it seems like we might have discovered a budget-friendly alternative to the AEM Bosch replacement O2 sensor.

So did it die already ?
I have used the cheap ones in a DA integra tuned on a hondata s300. I replaced the sensor twice in 4 years. I put one into an H22 accord recently and it didn't even last 6 months. I just today put up the $$$ for the real deal. I just hope to get at least 5 years out of it.
I haven't replaced a cheapie or bosch since I stopped waiting for it to warm up before starting. I read online that fries them faster.
Good to know
If you want to compare the accuracy of a sensor, to the official BOSCH, here is the procedure:
For each sensor:
1. Remove the sensor from the exhaust. Place in open air.
2. Set the gauge to 4-digit mode
3. Set it to display O2%
4. Set it to RCal mode. ( this does not work, if you do a "free-air-cal" )
5. Note the O2% reading, for each sensor.
Depending on your altitude/elevation, you should see a reading of about 17% to 21%. If both the BOSCH and aftermarket sensors agree on the %, then you have a functional sensor.
The readings at idle ( around 14.7 ) are meaningless. 14.7 AFR is "Zero" for a wideband. It's like testing a voltmeter's accuracy by measuring 0v.
I hope these budget sensors work out. Even if they last 1/2 as long :)
the real budget option is to pick up a balanger motorsports wideband with NTK sensor for $350. the NTK sensors last significantly longer and hold up 1000% better to leaded fuel. few more dollars than the aem up front but will save a ton of money in the long run.
you were a few houses away from driving by my moms house 🤣
You've been urging me for a while to sept up to that NTK + go boost, and I'm finally halfway there. On another note, I'm sure your Grandma can identify my truck by sound.
It's the O2 controller you have to watch out for. The CJ125 chip is being counterfeited by China and it is very hard to find a real Bosch chip. But it is possible the knock off chips could be better. The real chip design isn't that great, my concern for it would be the chip reading much different on a hot drag strip. All semiconductor stuff having performance swings over temp swings. But I have not tested to verify my concerns. I just built my own controller circuit instead. My channel has a video of me explaining the whole Bosch chip internals.
Thank you for your tech info ……. Sorry to see you leave the Nitrous guys behind your tech on that was great.
once i bought a cheap oxygen sensor from amazon, and the car ran like crappp
but it was not noticeable immediately, after driving for a week the car became extremely sluggish.
After fitting the Oem part the car became alive.
I had that happen to me on my Mazda. I'm always skeptical myself.
I didn't even know they made a cheap one. The next wideband I get is going to be the combo 02 and boost
let me know how it works for you.
great info. You be da Oxy Jen Sinnsor Kang I'm looking foward to the boost info you 'bout to start slangin, Keep it gangster dog, keep it gangster
How long did it last?
Good Tech . To Know ! Save $$$ On o2 Is Right ON TY Sir
Do you prefer the Aem over your old autometer wideband?
I have tried the cheap ones and the more pricey ones, and do not see a difference, neither last very long it seems, I am lucky to get a year out of either.
I have three cars and three AEM AFR's. I am finding the Bosch and Cheap ones are performing and lasting about the same (as ^ said).
I'm wondering, since four months, Is the amazon oxygen sensor still performing?? I have a authentic AEM 30-0300 unit that been working fantastic for 3 years. But im considering trying the knockoff ebay/Amazon $80 lookalikes to see if they preform equivalent to my AEM. what's your take/opinion on this?
My truck has been on jack stands for 3 months so I can't confirm the reliability yet.
Well no one's stealing that car lol
Leaded gas with a wideband LOL
I wouldn't buy any of them. Denso or bust 👍
