Denso universal is pretty darn cheap and, since it is OEM,
you can count on it, too.
I bought one from Amazon recently and am satisfied. A few
years ago I bought an exact fit one from
www.automedicsupply.com at a great price, too. (These were
for two different Hondas.)
Aftermarket O2 sensors do not have a good reputation, from
my general reading.
Typically your options are a universal fit sensor and an OEM
replacement. The main difference in my experience is the OEM
replacement has the correct plug already attached, and it costs twice
as much as the universal fit sensor. The sensor element itself is the
In the case of a 4 wire O2 sensor, the 'universal' fit sensors will
usually come out of the box with...4 wires hanging loose. You get to
wire it up yourself, which if you are handy with a soldering iron and
shrink tubing you can do a professional R&R job in 20-30 minutes time
and save yourself some money. Or if time is more important, buy the
OEM version, and then you just unscrew the old one, screw in the new
and connect the plug.
Because the ones Bosch sells to the aftermarket are NOT NECESSARILY made
in the same plant or to the same design as the ones they sell to auto
manufacturers. The Bosch aftermarket replacements, even when labelled as
OEM replacments, tend to have a much higher failure rate.
Don't buy Bosch. Bosch OEM and Bosch aftermarket may be made by
different vendors, even for the same application. That's been beaten to
death on the Mopar forums over the years, and unless something's changed
in the last year or so the failure rates (including bad out of the box)
are very high in Bosch aftermarket sensors.
I'd get a planar type sensor from Bosch. These are more resistant to
contamination than out of date thimble types. Don't care for Denso
sensors. Looks like Honda has good sense to use more expensive Bosch
on some cars. But manufacturers buy in batches, lowest bidder wins.
No problems with Bosch. However, they also re-distribute other maker's
parts. You can actually get a Denso in a Bosch box!
why do you always flog bosch dude? are you sponsored in some way?
there's no one else on this group i've ever seen agree with you. quite
the opposite in fact - and fwiw, /my/ personal experience with bosch has
I don't work for Bosch . Just here to talk about the good, bad and
ugly of cars.
We all have different experiences I certainly respect that. I don't
doubt your bad experiences with Bosch, but I've had excellent luck
with them. Especially the planar types, using them to fix cheap Denso
junk related problems like the P0420 converter efficiency problem (no
converter replacement necessary). As some pointed out, Honda actually
uses Bosch in some cars. Toyota TSBs replaced wideband Denso junk.
If Denso junk work then use them. Fram oil filters and Bridgestone
tires work for many too. So the owner decides.
with respect, i think you're confused. just because a sensor is
wideband, doesn't mean it's bosch or some kind of re-labeled bosch.
so exactly why do you think denso are junk? i've worked with both - not
only is denso better build quality, they last longer. i ask because i
don't understand what you're looking for that makes the difference to you.
if you mean that just because it fudges a "pass" on a smog check because
it has looser tolerances aimed for exactly that purpose, /i/ don't think
that makes it better quality, i think it makes is a fudge.
Most Hondas use better parts like NGK spark plugs (I prefer NGK
Iridium-IX or Laser-Iridiums), Nissin/Findlex/Akebono brake pads, and
Gates timing belts, not the cheaper Denso, NBK pads or Mitsuboshi/
Bando that's showing up more unfortunately these days.
IMO Denso's lower tech stuff work fine. More sophisticated things like
ABS module they still have to use Bosch or licensed builds from Bosch.
