It absolutely works and gets you started quickly

The best and easiest way to fix a burned out spark plug. It would be nice to know the torque setting. After tightening twice, it worked perfectly. In a 404,000-mile Triton engine in a 2000 F-150.

Pros
  • Top marks for support and durability from testers
Cons
  • Updates available

Best on the market

This will save you money on an expensive $3,000+ replacement head. I installed and was running quietly with no noise within 5 minutes. Red Loctite for high temperatures on screw threads

Pros
  • New
Cons
  • I won't say anything

Life Saver is good for Engine Parts

If you drive 97-03 F150 V8 this item is a must have. If (not if) your engine blows the spark plug out of the cylinder head, this kit will save you from heartburn. This permanent repair is easy to install at the curb with just a few tools. I installed two sets on my truck, one with 50km mileage.

Pros
  • Cool Product
Cons
  • Upgradeable

Best Thread Kit: Cylinder Heads

Do yourself a favor and buy this kit. Very easy to install and works as intended. This kit can be used away from your garage, also on the side of the road if needed. I have 3 spares with me just in case. Don't forget to also remove the required sockets, ratchet, flex sockets, extensions and thread-locking and extra spools and you're done. Eases anxiety when Ford executives decide to spit out the spark plug when miles from home.

Pros
  • Outstanding Design
Cons
  • -

DO NOT BUY THIS for engine parts

I used to think Dorman would sell a decent product but after trying to install this cheap repair I wasted 8 hours in a headache! I installed the base in the head and plugged in the spark plug. As soon as I took the candle out by hand, the top part of the insert broke off! I had to drill out the broken part, cut a hole for the spark plug and install a healing coil. What should I have done first! Thanks Dorman for the crappy product and looking forward to my Sunday.

Pros
  • Easy install
Cons
  • Questionable purchase for seniors

As effective as drinking gypsy tears to gain longevity.

Not a temporary solution either, a waste of time and money. I installed it according to the instructions, waited for the thread sealant to set, started the engine and immediately my plug popped out again and the noise was back. Do yourself a favor and don't waste your teeth or money on this product. Either buy one of the best and take a risk if it doesn't work, buy a new head for your motor, or junk the car if the cost is so low that the motor isn't worth buying. It doesn't work at all. I guess

Pros
  • Hard-wearing finish
Cons
  • I don't like it at all, everything is fine

Spark Plug Repair Kit

When I first used the kit I was scared because I heard the insert was broken or it wasn't closing properly or it wasn't over tightened. So I was too careful to put it through my head. I also used Red Locktite which should seal the threads and be permanent. But out of caution, I didn't screw the insert all the way in. And two days later it started ticking and smoke gases seeped into the candle shaft. So I removed the insert, cleaned it and re-cut it with more torque JB weld to make sure it lays…

Pros
  • Quality Construction
Cons
  • Easy Repairability

Worth Trying Engines & Engine Parts

2001 Ford 5.4 Triton. 4 stars because this is theoretically the easiest way to fix a popped plug and avoid drilling the head. The spark plug/cabin design is also neat. But I had some problems with the installation. Several reviews mentioned outlet selection, but I underestimated how critical this is. On my first try I found that the bushing stuck well to the adapter in the spark plug and took hours to remove. YMMV, but most of my 17mm sockets fit the spark plug snugly but are too tight on the…

  • Great for a Small Home

The best repair at the best price!

Firstly, you are probably reading this review and looking at this product because you have a problem. I bought this as a backup but Dorman 42025 and NAPA 600-3248 are identical and I'm actually part of NAPA but it's less than what I paid for NAPA on the auction site. In fact, Revain has the best price ($37.42 and paid for free shipping) I've found. They average around $70 at dealerships and 40+ on this site, can't mention. I have a 1999 Ford Expedition with a 5.4 liter Triton engine and it had…

  • Decent Performance
