My Triumph Daytona fast sensor is made a little different. The sensor is surrounded by a brass tube which is an extension of the brass base.
The brass tube has a few holes in it to allow a little flow of air through it.
This way the little expose sensor does not get the direct blast of air on it.
Unfortunately the place I got mine, no longer carries it. And when I search for it, I can not find it. Part # is T1900510 while dudemaaan's is # T1290510.


Got it from:

Sounds like it would be much more durable :001_302:

wannaspeed.com has a few more of the sensors in

I've had no issues with quality or durability of the wannaspeed sensor in my car, but it doesn't respond as fast as I thought it would - still better than stock, so I guess that's what matters

The sensor responds pretty much immediately. If you aren't seeing quick changes in air temperature readings it's probably because the air temperature isn't changing rapidly, at least from where the sensor is reading it. In my bench testing just breathing hot air on it caused rapid changes in resistance. You might also make sure the sensor is clocked properly so the air flows through the plastic square area rather then into it. Not sure if it makes a huge difference or not but maybe.

mazda used an open element iat's on the second gen rx7's

On some other 13Bs powered cars, Mazda placed the AIT sensor in the throttle body elbow where it would not heat soak.

:dunno: Mazda is inconsistant! :confused:

As to durability, I've had my wannaspeed sensor now for about 30,000 miles. Relocated pre-throttle-body. That's close to 50,000 kilometers. Still functions as new.
I know two others who've had the sensor for a few years. No reported issues.

What size are the threads on this? 1/8 npt?

I know this might not answer your question, but they are exactly, the same size, and thread as the OEM sensors... Making them a drop in fit...

I have a custom manifold that doesn't have a port yet, so I'm trying to figure out which bung to weld on.

Not sure what your set-up is, but some of us re-located it from the stock manifold to post IC/pre-throttle-body. Less heatsoak.
As for what thread size, just take it to a hardware store that carries metric and find a nut that will work. It's metric, but not pipe thread.
If I get a chance to get down to my shop I'll try to find my old OEM IAT and see what size it is...

Thread size is M10 x1,25 if my mind serves right :)

Can you link me up please? I've had a quick look but couldn't find it under sensors/switches.

Thanks

I just tried to order this and they're currently out of stock since the supplier stopped supplying the sensor
