Questions & Answers

This is compatible with m12 x 1 spark plugs. Isn't it 25?

Hello,br>Yes, it will fix a M12x1 that has been damaged. It will enlarge the damaged M12 thread, which will then be reduced by the inserts. Thank you. br>br>

Are the m12x1 id threads? 25? What is the diameter of the OD thread? Is it necessary to drill out the old threads that have become damaged?

yabr>Get the regular plug size specifications for your Ford truck (google Ford truck year and model plug)br>br>Then don't overthink it. br>Once you have this information, go to Amazon and look for a steel thread insert that is at least 1/2 inch long. The size of the tap will be determined by this. The tap drill size for that insert O will be determined by the tap size specifications. threadbr>Call the Salt Lake Ford Truck service center for assistance. They are experts in this field.br> br>About ten years ago, they did it for me. On a cross-country trip near Salt Lake, I blew a plug/coil out into the hood, costing $600 and taking 3 hours. br>Should get rid of the chips. However, because they are Alum and the cylinder wall, valves, and rings are steel, this may not be a major requirement. br>Again, if Salt Lake Ford Truck Service is still open, I'd call and inquire politely about their thoughts.br>Best of luck.

What is the thread size on the inside of the insert, and what is the tap size?

Of course, there's a plug thread inside.br>Google F150 4. 6L plug thread size.br>br>The difficult part, if you want to do it with the least amount of risk of future cylinder wear, is removing the chips after drilling and tapping. br>Alum will be used for the chips. = softer than steel (cylinder walls, rings, and valves), so it may not be necessary to do so, but softer metals can still wear harder metals (even plastics) under the right conditions. Salt Lake Ford Truck Service Center is the masters of this on Ford's F series. br>They did it for me once for $600 and completed it in 3 hours while I was on a cross-country road trip. br>I'm hoping they're still around.

Is it compatible with the Ford F150 4th Generation 2009? If the thread size is the same as mine, I'm concerned. ?

But I'm not sure.br> I was driving my F150 4 several years ago. The 6L blew a plug/coil out of its threads (alum) into the hood while passing through the Salt Lake area. br>Turns out there is (or was at the time) a great Ford Truck service center nearby in Salt Lake, and they fixed it in hours for $600. They had everything set up to drill and tap it out, vacuum out the chips, install a steel insert, and then replace the coil. plug in.
. around ten years ago They were well aware that F150s are prone to this type of problem. br>I'd save time by going straight to the source and asking them. Tell them you've already had it done by them and want to do it yourself now. br>They ought to inform you. If they're nice, that is. br>To find their phone number, Google them.br>Best of luck!

Selected User Reviews For AB Tools-US Pro Spark Plug Rethreading Tap Thread Repair Set Kit M12 x 1.25 with 4 Inserts

Although there are no instructions, it is usable
4/5

HIGHS: Budget price for a 12mm repair kit (there aren't many options in that size). Shouldered inserts are used instead of helicoils because they don't leak as much. LOWS: There are no written instructions. If you don't use special ultra high-strength inserts, they may back out. Threadlocker with a high temperature rating (I used Vibra-Tite rated at 2000 degrees). The drill size isn't written on the tap. I couldn't get the tap to start with a 31/64" hole, so I increased the size to 1/2", which resulted in a much looser fit than I desired. The threaded end of the closest size insert was a little too long, so it had to be ground down. I used a small amount of high-temp sealer near the top of the insert, and the end result was a repaired spark plug threading on a 1200 Sportster with no leakage, so I'll give it four stars.

Beginning is difficult
4/5

Cutting new threads is fine, but you have to drill out the head to the point where the tap can start, so I had to pull the head to get it to work. It was, by the way, used on a stihl chainsaw.

What was I thinking waiting so long? A 95 Honda 800 v twin has a cross threaded spark plug
5/5

I tried the back tap tool. . . it's not bad, but the plug won't "sit" properly. . . I used this instead. HUZZAH! br>Don't forget to use thread lock on the outside of the insert;.

With success, a budget-repair tool
5/5

It's not Time Sert quality, but it got the job done for a fraction of the cost. Make sure to get the tread locker to keep the insert in place!.

I was able to save the day
5/5

It was a little thinner than the common brand, but it saved my 2013 Dart 1 from losing its head. 4 turbo. With patience, it worked like a charm. To remove metal chips, remember to use grease with the tap and clean every 1/4 turn or so.
