Denso all the way

 

yea i figured denso and ngk were the best but are they still good quality comin from cheap bay (ebay)

 

denso is denso, no matter where you get it from.

 

ok thanks now the second problem is buy an upstream and a downstream how do i tell them a part

 

I would use rockauto instead of ebay. Probably better pricing and you know yyou're getting genuine parts.

Don't get a universal sensor. Buy a "direct fit" with the plug on it.

There's no difference between down or upstream except maybe wire length. I'm assuming this is for a D16Y7.

Buy NGK or Denso. Bosch or any other garbage won't work. You'll most likely have a CEL on day 1.

 

By part number

 

yes this is for a d16y7 and are you positive about the up and down being the same. i know that one is pre cat the other is after it i dont think it makes that much of a difference but i dont wanna have cels

 

ok so im looking on rockauto and i found some but some say there for th gx or dx models or there for auto trans does this make a difference, would i be able to put them on my manual

 

Really? I thought upstream was heated, downsream not? They are different part numbers.

 

no they are different upstream regulates something or other and the downstream tells when ur cat goes bad

 

they're both heated. They are actually the same sensor with different length wire.

 

OK so im buying them of rock auto thanks for telling bout that site, but i'm trying to figure out if the O2 sensors for the DX civic are different from the ones on the CX cause i have a CX hatch but the DX O2 sensors are cheaper i'm just wondering if there the same of if I should just buy the ones for the CX model
this is the sensors i wanna buy 2 of http://www.rockauto.com/catalog/more...895&cc=1363047

 

Are you positive about this cause if so ill buy to of the same causse there cheaper and just splice more wire so it reaches my cat since i put aftermaket exhaust on

 

Just buy an extender(20$) don't hack job it in, that being said i bought a no-name 20$ o2 for my teg(track car) and it lasted a year with no CEL's an no mpg loss lol. I've got an AEM UEGO now but just figured i say even the cheapest of cheap can work.

 

kk thanks a lot man but that doesnt answer the question of if i buy 2 up stream o2 sensor for dx model hatch it wont change anything

 

The ONLY difference is the wire length i can promise you that along with 2 other knowlageable posters have said this too. i've ran an up stream as a down and vice versa...yes i had a d16y7 at the time so they were right by eachother. No cel's bone stock 99 DX.

 

i just wanted to be 100 percent sure and one more thing i found some extension on http://passwordjdm.com/PasswordJDM-O...P1767C320.aspx and is 16 inches to short or should i get the 32 inch but to me neither seems long enogh

 

this is a stock civic dx right ? with the CAT in the manifold ? if it has it underneath the car then 32 is more then long enough.

 

stock cx there basiclly the same car and alright thanks a million just made my week 10 times easier

 

DX/CX sensors are the same. Sometimes rockauto has mistakes in their catalog. I would check the Ngk Or denso site for part #'s and make sure they match.

They are both heated and are the same sensor....they have different length wires.

yea i checked it on denso and i put in my model car and it brought up the part im going to buy same part number just different engine seems all the same to me

 

so i ordered the 2 O2 sensor i would like to thank all u guys for ur help even if it seemed like it was going no where but i wanted to make sure i got the right parts and not have to kick myself in the **** for buying ebay crap or something that falls apart and i hope the forum help other ppl
