Be careful, you cannot fix mistakes. - I used this spark plug rethread kit on a 1964 Johnson 9.5 hp. Worked great. It's difficult to use if there are still some threads left in the spark plugs hole. But I used my small impact driver very carefully to chew up those treads. It seems the threader also hones the spark plugs holes before it starts treading. After inserting the threader about 1/3 with the impact driver, I did the rest with the Rachet and a socket. It worked perfect. I screwed the spark plugs in with the insert and used the Permatex Red thread lock on the insert threads only and after 24 hours I remove the spark plug and the insert is in there hard has a rock. This was a life saver. There are probably better ones out there that will be easier to use. But this one works to. You will need a lot of elbow grease and more than an hour to make it work. I recommend you remove the head after because no matter how much grease you put on the threader, there was a bunch of shavings in the cylinder when I removed my head. Review: ABN Spark Plug Thread Repair Kit - I stripped a spark plug thread on my Kawasaki 21hp engine on my 2006 Ferris zero turn mower. I first tried a 14mm thread chaser but spark plug would not tighten, so I purchased the ABN repair kit with reamer and inserts. I removed all cylinder shields from engine (Still mounted on mower) so I could get a good look at the spark plug hole. I had to use a 1/4" battery powered impact to be able to get the reamer to start cutting for the plug insert. I covered the reamer with grease and when it started to cut the new threads I then used a 1/2" ratchet to slowly cut the threads. I removed the reamer/threader after about 2 turns and cleaned the grease and cuttings off, repeating this until the new threads were completely cut, then I cleaned the new threaded hole in the head. I then screwed the proper insert onto the new plug until it bottomed out and put red thread lock compound on the outside of the insert and screwed the spark plug with the insert on it into the head and tightened the plug to seat the insert. I removed the plug and the insert was completely seated. I then reinstalled the new plug and tightened to specs. The engine runs properly now and I mowed about 2 acres with it. The only downside is there is no instructions with the kit, that is why I wrote this long review. I can recommend this kit for anyone that strips a spark plug hole. ## Features - REPAIR PLUGS: The ABN Thread Repair Tool Kit is a time-saving kit that allows you to cut threads to fix a stripped and damaged 14mm spark plug threaded hole port and repair plug configurations in aluminum heads; Socket includes metal retainers to keep plug held inside during install and removal - VARIOUS APPLICATIONS: Chrome-vanadium steel (CR-V) M14 x 1.25 internal thread size on repair sleeve suitable for damaged spark plug threads to clean and rethread spark plug ports on a BMW vehicle and some Nissan and Toyota engines; As long as the head is aluminum and the spark plug hole is straight with room to turn the tap using either a ratchet or wrench, this kit will allow you to repair plugs without removing the head - EASY TO USE: Rotate the crankshaft to make sure no ports/valves are open, use the tap to install new threads, choose the proper depth of insert, and screw it firmly into the newly tapped head; Apply grease on the tap to help catch any metal shavings (rather than letting them drop into the cylinder) and back out the tap out every half turn to every whole turn to clean the metal shavings from the tap; Grease recommended, not included - PERFECT SIZE: 14mm reamer with 12 points; 2.5-inch overall length; Use with 3/8-inch drive ratchet or wrench; Inserts sizes are 3/8-Inch, 7/16-Inch, 1/2-Inch, and 3/4-Inch; Tap is tapered to allow the tip to fit and rethread the hole in order for the coil to fit; Measure your plug diameter, thread, and pitch to see if this kit is compatible - PACKAGE CONTENTS: Rethread kit includes a tapping reamer and 4 different depths of inserts for your convenience ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00QKPB620 | | Automotive Fit Type | Universal Fit | | Best Sellers Rank | #193,450 in Automotive ( See Top 100 in Automotive ) #27 in Thread Spark Plug Thread Repair Kits | | Brand | ABN | | Brand Name | ABN | | Compatible with Vehicle Type | Car | | Core Material | Copper | | Customer Reviews | 4.0 out of 5 stars 416 Reviews | | Global Trade Identification Number | 00617209838923 | | Item Weight | 0.14 kg | | Manufacturer | ABN | | Manufacturer Part Number | 8923 | | Model Number | ABN-8923 | | Thread Size | M14 | | Top Material Type | Alloy Steel, Metal | | UPC | 617209838923 | | Unit Count | 1 Count | | Vehicle Service Type | Car | ## Product Details - **Brand:** ABN - **Core Material:** Copper - **Thread Size:** M14 - **Top Material Type:** Alloy Steel, Metal - **Vehicle Service Type:** Car ## Images ![ABN Spark Plug Thread Repair Kit, 14mm Reamer Cylinder Thread Repair Tool & Thread Insert – Spark Plug Rethreader Kit - Image 1](https://m.media-amazon.com/images/I/71Em9Bhq20L.jpg) ![ABN Spark Plug Thread Repair Kit, 14mm Reamer Cylinder Thread Repair Tool & Thread Insert – Spark Plug Rethreader Kit - Image 2](https://m.media-amazon.com/images/I/81ZLXuBAPLL.jpg) ![ABN Spark Plug Thread Repair Kit, 14mm Reamer Cylinder Thread Repair Tool & Thread Insert – Spark Plug Rethreader Kit - Image 3](https://m.media-amazon.com/images/I/81ekrLRuG7L.jpg) ![ABN Spark Plug Thread Repair Kit, 14mm Reamer Cylinder Thread Repair Tool & Thread Insert – Spark Plug Rethreader Kit - Image 4](https://m.media-amazon.com/images/I/81FBXEI7d7L.jpg) ![ABN Spark Plug Thread Repair Kit, 14mm Reamer Cylinder Thread Repair Tool & Thread Insert – Spark Plug Rethreader Kit - Image 5](https://m.media-amazon.com/images/I/81lF6Opdb3L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Hard but works.

It cut threads well, but it took a lot of effort. I would cut threads for 3/4 of a turn and then back it back out and remove chips from tap and re grease. Kept this up until all the threads were cut. They looked good and I used the small insert to get my lawn mower repaired. Spark plug threads in nicely and mower working again. ## Frequently Bought Together - ABN Spark Plug Thread Repair Kit, 14mm Reamer Cylinder Thread Repair Tool & Thread Insert – Spark Plug Rethreader Kit - Loctite Threadlocker Red 271 - Permanent Thread Lock Glue for Nuts, Bolts, & Fasteners, High Strength Screw Glue to Prevent Loosening & Corrosion - 6 ml, 1 Pack - Spark Plug Insert, 14mm-1/2, Compatible with Dune Buggy --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://guam.desertcart.com/products/20252549-abn-spark-plug-thread-repair-kit-14mm-reamer-cylinder-thread](https://guam.desertcart.com/products/20252549-abn-spark-plug-thread-repair-kit-14mm-reamer-cylinder-thread) --- *Product available on Desertcart Guam* *Store origin: GU* *Last updated: 2026-10-23*
