Yes I have in the past used an economy O2 sensor, and they are absolute junk. They may work fine in the beginning but they soon begin to fail. My personal rule is that critical engine or emissions sensors are only replaced with exact oem parts. O2 sensors live in one of the harshest environments that a vehicle has, they live in a extremely hot and corrovive enviorment and need to be excepionally precise, accurate, and robust.OE sensors are expensive and O2 sensors are a perfect example of "you get what you pay for". Most o2 sensors use zincromium which is an expensive material, a bargin o2 sensor has to cut expeses somewhere, they usually use lower quality material that may do the job, but not for long. Given that the o2 sensor manages air/fuel ratio and cat temps Im unwilling to use a cheaply made sensor that can damage some very expensive components. I'd rather spen $150 buckson a oe sensor than $75 bucks on an economy sensor that destroys my $1000 catalytic converter or that leans out my mixture so much that I hole a piston.I have always bought Bosch or NTK, but now wondering if the economy brands such at API ot Ultra power are just as good.
Anyone have experiences with the economy O2
Sometings yes, and sometines no. Anyone who has ever worked in a marketing Dept will tell you many high end produts are sold on perception. I have found off brand products 100% indentical to name brands in some cases but at half the price.The old saying goes, you get what you pay for.
We bought a few whitebox air fuel sensors lately. Every single one has worked perfect. Functionality was verified thru extensive data logging on Ecutek tuned vehicles. As far as how long they will last, your guess is as good as mine.Put a cheezy ebay o2 sensor in a 2002 prizm. Hated it. Threw a code for "thermostat too cold", wild goose chase on it, but looking at the live data it came and went.
