I was doing a lot of weight reduction today which includedtaking off the old r12 system. In doing so I took off my maf sensor and poked a wire on the inside and know that screws it up. I found a maf that I think would work at advanced that looks way easier to do stuff with and not ruin it. http://shop.advanceautoparts.com/web...985%7CL3*15345#

If it wont work I do want one cheaper so if someone even has one on here that they changed to carb or... I would love to buy it off you!

 

Wells used to make the SU-145 maf which was higher flowing then stock
. I still have one of the original Wells on my car. It looks
their film design which is better the wire on the stock one.

 

So would this one work and I would have to tune them right? If so where at?

 

I ask this cause dont you have to tune all the maf's even the stock ones or is that just something that wasn't right that I read?

 

No, you do not have to tune the Maf on 3rd gen cars, the ECM will do that by itself. Just make sure that Wells Maf will work on a 3rd gen TPI car. Also that price is about right on.

 

I think what the op was wanting to know was is a maf from a different application would be a plug and play. The answer is no. The have been other mafs that will work on tpi maf slp used a Bosch from a porshe. The is a ford maf that requires rewiring and re calibration of the GPS air flow tables. The best thing to do unless you want to do alot of research and testing and tuning is to go with a used Bosch tpi maf and stay away from others like micro tech.

I checked in the PDF version of the parts microfiche and came up with these numbers:

1985: 14971243, Delco 213-162
'86 - '87: 14094712, Delco 213-163
'88 - '89: 10055877, Delco 213-161

You can use one from a 86-87 but the 88-89 seems to be better.

What about this one? It says direct match for 87 firebird and would this increase flow at all?

 

Your profile says you have. Lb9 no need for more airflow through the maf. The wells will work but aftermarket ignition parts can be problematic better going with oem. In this case used.

 

Why would aftermarket ignition be a problem? I have a 6A box and coil, Didnt do a distr. And I hbave been looking to up my engine some day so it wouldnt be a terrible thought

 

Cheap over seas parts = poor quality and reliability
Unless you are maxing the maf 255 GPS and are close to 500hp I'm not sure what you are looking for ?

You can waste you coin on this.

Its not just about power, If I go back to a stock one then I can easily poke another wire, This doesnt really have wires that break as easily and for 20-30 dollars more with less risk of breaking again and possibly more flow whats there to lose? Is my ignition not going to work with it? Or what other things could be bad about it. Then the one you showed is almost 400 which is almost 250 more

 

I have posted 3 likes to various mafs, your msd will be fine I was referring to parts reliability .

 

The Wella Su-145 will work just fine, I have used this same part number for over 12 yrs. Do a seach on this Site using Wells Su-145 and you will find a load of good info about this Maf.

 

That looks like a new variant on the older deign thick-film sensor that was in their first OEM replacement. I know the older one reports a correct analog signal for g/S. I suspect this one is calibrated about the same, but would have to check with an old contact in Fond du Lac to verify this. Regardless, if you do decide to use this MAF, resist temptation and leave the inlet honeycomb matrix flow delaminator intact, or you likely WILL have problems as TunedPerf reports.
