Try this AC Delco part number 213190. It's listed for an 87 Buick Grand National among other things. rockauto.com has them for $25 and lists it as 3/8 npt.

Hey Sess, what did you mean by this? haltech only has one style of sensors, their new systems, E8 and E11, an read from most all modern sensors, but thats about it.

i didn't find it on their website but they mentioned that u can specifiy meteric/standard on the sensors.

one x i installed was all standard but my x that i just got as both meteric/standard sensors now.

I think they killed that idea since the newer models just use the old one. Pretty sure they are different sized of sensors between the two x's that i recieved.

Wow, I thought all O2 sensors were 18mm x 1.5?

You are right Ret, all O2 sensors have the same threads. And people, just go to your favorite auto parts store, ask for what ever 3 or 4 wire sensor they have in stock, and is the cheapest, and use that, make sure you know that each pin is, to connet it right.

Here is a spot they have the coolant sensor for $17

Here is a nice cross reference on what else the sensor is used in...

This is the Autozone part number for it
Wells SU109

At least I think I ran one of the car types and that part number came up. I liked the $7 price...but double check that.

Did some googling on the GM air temp 25036751

Seems like the cross over is the Wells SU107 and Autozone has them for $22.

Found that on this forum...

Well, I just crossed the air temp part number at Advance Auto and found the GP Sorensen 779-19001. It was $14. It is definatly lower quality then the sensor I got from Haltech.

But it is just an airtemp sensor.

Well, I went and tried to put the Advance Auto 779-19001 and i I picked up a Wells SU107....

I have no idea what size NPT those threads are but it is MASSIVE. The OD of the threads are .61 "

I am gonna try the GM dealer to see if I can find the temp sensor that uses 3/8 NPT.

James

does that pictured air temp sensor directly replace the stock one on the throttle body elbow?

No you dumbass, he said it was NPT thread.
The stock air temp is 10mm x 1.0.
You want something "close", use the stock FD one or anything off a Honda.


-Ted

I am not sure what I was talking about when I posted that....


A 3/8 NPT - 18 is the right tap...now just if I could find one in this town:(

James

damn you can be a rude little man at times, I did not see anywhere in the pictured post where he mentioned that....fuck face.

I was just trying to find a air temp sensor that fit in the stock TB elbow location.

Didnt your mother tell you that if you dont have anything nice to say, dont say anything at all??

Ohh thats right she was too busy with me to tell you that.

Honestly ReTed I respect you knowledge but completely laugh at your arrogance and lack of personality.

I thought you two knew each other or something:)

I am gonna have to say good luck on finding something that will go in the stock hole.

Asuming you already have a drill set...the tap to do the job will run you 6 bucks or so. Might be less trouble getting the GM sensor or equivlant and the tap then finding something that goes in the stock hole.

James

Wow, you're a godamn comedian now...

Why don't you get some brains, cause all of that shit would've all popped up if you were smart enough to do a proper search.

Oh yeah, that's right...you got no brains.

So I'd figure I'd be nice and TELL YOU what you're looking for.
At least you can't fault me for trying to bang some knowledge into your head.
