I am also not as confident in this repair as I was in the Time-Sert repair but since this costs about 10% what the Time Sert does this was the right choice for my 14 year old truck."
"This worked fantastic for my 2000 Suzuki Hayabusa to repair my stripped oil pain drain plug threads."
"The threading tool that came with is very high quality and made some beautiful threads."
"Word to the wise, put a dab of grease on the tap and def wrap a piece of tape around where the extension plugs in so when you go to pull the extension out you don't lose the tap in the tube and have to try and get it out."
"Changing out spark plugs on my 2001 Honda civic got to number 3 cylinder on it started to get super thight and you could feel the threads starting to strip I thightened it back in so I could still drive it until I had the money to fix ( time sert kits are expensive over $200 for the kit) then I found this kit ordered it and worked great only took about an hour with a few beers while doing the job."
"Seems to be holding though, and allows you to use the original spark plug style, unlike one of the other repair kits that forces you to change to the "long reach" style plug, which could cause a check engine light."
"This product is amazing it literally took me 20 minutes to fix my F 150."
"Make sure you out a ton of grease on the tap to catch all the aluminum shavings, then I used a thin metal rod with q tips taped to it so I could reach down in the spark plug "valley" to pull up any loose shavings."

"The heads were in place, still on bike and wasn't difficult to drill & tap out the area, had sufficient working space between frame & heads."
"Worked like a charm."
"This was my first time and it worked really well."
"Great thread repair kit best on the market."
"Helicoil product, works well."
"The parts were good...The problem I had was the picture didn't match the product..The picture shows a triangular installation tool..There wasn't one in the package..I have a feeling the manufacturer changed up and the new picture without that tool wasn't changed yet.....Otherwise a good product..They sent me an RMA to return it.Very quickly...To go buy a tap handle would cost like 7-8 dollars plus my having to pay the return postage,it isn't really worth returning it..I bough a whole tap and die set,which includes the tap and handle I needed for $12...."
"the insertion tool in the Fix-a-thread kit also doubles as a tool to break of the tang. And the set is cheaper."

Find Best Price at Amazon"I originally almost bought the OEMTOOLS one 25602 as I've seen them, however that kit only came with 3 coil inserts. However instead of using a 1/4" ratchet, I ended up using the handle of my old heli kit as it had a 1/4" square hole for the tap that would allow me to apply even level pressure to make the tap thread better. There are two versions however, one version the coil insert tool also has a 1/4" socket hole in it to use wit the tap."
"Took about 30 minutes to fix the 2 bolt holes on the mower, didn't have to pull the motor, could access on the deck which was a huge time saver."
"I had the 7 o'clock bolt hole strip that holds the derby cover on my Harley."
"I got this to repair a stripped out muffler bolt hole on the exhaust manifold on my walk behind mower. Within a couple of weeks I had to use it on my grill when a bold head snapped off when I was replacing the burner unit and then one of my bench tools needed to be repaired as well."
"SO easy, it seemed to good to be true. Pros. quick and easy. enough inserts for many more fixes. saved me LOTS of time and money. Cons. enough inserts for many more fixes = $$ (cheaper kit with fewer inserts would be nice). need your own 17/64 drill, which is in most bigger drill sets."
"Best to use ratchet and square head adapter than T-handles to cut threads and install the Helicoils."
"This worked great to repair threads."
"I NEEDED what was pictured... a bottoming tap."

"I used it on my '84 toyota pickup (22r), and I really disliked cutting into that aluminum head but it seemed to go ok. I managed to hit the piston while I was threading (hand smacks forehead) so make sure you either don't get all cavalier with your wrenchin' or ensure your piston is out of the way."
"I used this to fix my stripped threads on my 2005 Ford Crown Victoria."
"cb360 blew a plug and I bought this to replace it."
