Mass Air question..... November 05, 2007, 11:07:23 PM Will a Mass Air sensor from a V-6 work on a V-8 if the injectors between the two engines are the same? Quote Selected
Mass Air question..... Reply #1 – November 05, 2007, 11:35:54 PM i dont thin injector size matters as thats what the computer controls. if you mean only the sensor i would imagine you'd need to find one that puts out the same output voltage at the same conditions (density of air) as stock. all the computer see's is voltage and it componsates, it doesnt care where it gets its voltage or what the voltage really is, it just adjusts fuel from what its told by maf sensor voltage.

Mass Air question..... Reply #2 – November 06, 2007, 06:58:52 AM So,a Mass Air sensor that can come from a V-6 car can be used on a V-8 car using the same injectors,just two more of them.Right or wrong? Quote Selected
Mass Air question..... Reply #3 – November 06, 2007, 07:23:10 AM i would think its doable i mean if its same plug same everything onlything you can do is look at the part #'s between the v6 and the v8 mass airflow meter and see if they match up.....plug same #'s match up probly gonna work....mass airflows just measure incomming air i dont think it matters so much as the #of cyls....because look at gm almost all of the v6 and v8 motors have the same mass air meter....so if its sitting around try it......

Mass Air question..... Reply #4 – November 06, 2007, 07:33:16 AM Probably different man.Due to the fact of air flow metered.v8 is going to suck in more air than a v6. Quote Selected
Mass Air question..... Reply #5 – November 06, 2007, 07:51:57 AM I tried to put a Mark VIII meter on my cougar with 19# injectors and it didn't work. So I put the 19# sensor back on it.The casting is what you need to wory about. The sample tube inside is tuned to the size of the injectors is what I found out. Quote Selected
Mass Air question..... Reply #6 – November 06, 2007, 07:56:16 AM I found a chart a long time ago on the intarweb (that has disappeared) that showed which motors/injector combos used which MAF meters. It even showed the factory ford part# for the sensors. Many v6 and v8 motors did in fact use the same sensor. I just wish I could find that chart again. You'd know exactly which ones you could use.

Mass Air question..... Reply #7 – November 06, 2007, 01:02:26 PM What’s the part #?Maybe it’s a universal ford part# Quote Selected
Mass Air question..... Reply #8 – November 06, 2007, 01:06:22 PM Well,the Mark VIII sensor probably didn't work with the 19# injectors because a Mark VIII uses 24's.I don't have a part number right now.I'll try to grab the sensors this week.I'm grabbing them both because they are free,and,if they DO work,I'll have one to sell with a set of 24# injectors (an extra set).

Reply #9 – November 06, 2007, 01:48:03 PM Quote from: vinnietbird;186424Well,the Mark VIII sensor probably didn't work with the 19# injectors because a Mark VIII uses 24's.Thats what I was gettting at. Its the casting thats different for different injectors. Because I can swap the actual sensor from casting to casting and it will work. They had the same part numbers on them but the casting had a bigger opening for the air to flow across the sensor. Quote Selected
Mass Air question..... Reply #10 – November 06, 2007, 02:16:44 PM I found this: http://www.micro-tech-auto.com/images/pdf/mafcat.pdfIt has an OEM parts interchange list on it as well. It's not the chart I was refering to, but it works. Quote Selected
Mass Air question..... Reply #11 – November 06, 2007, 09:06:25 PM I'll grab those sensors and check the numbers.Thanks a lot. Quote Selected
Mass Air question..... Reply #12 – November 07, 2007, 01:53:54 AM I used a mass sensor from a v6 car,70 something mm, don't do it...it will run very fat and you will end up replaceing your o2 sensors. Trust me on this, stick with a V8 sensor or swap the sensor portion of it to a 80mm(plastic housing) and you will have no problems.J Quote Selected
Mass Air question..... Reply #13 – November 07, 2007, 06:26:51 AM No biggie,I'll wait until I have everything I need.I'm not going to just start throwin parts at it.I'll talk to Kitz,he may have what I need. Quote Selected
Mass Air question..... Reply #14 – November 07, 2007, 04:23:14 PM A sensor for a '95 300 I-6 is the same as on the wifes '93 4.6 Grand Marquis... SOME ARE THE SAME.... Others are not.... Quote Selected
