Review: Great product, saved a lot of money with this and modified this tool to be able to repair CBR 600 spark plug thread. - Used this to repair blown-out spark plug threads on my 1995 Honda CBR 600 F3. After my spark plug blew out I was stuck looking for a solution to repair the threads. I avoided removing the engine or cylinder head, was able to make the repair with the help of a right angle drill attachment with everything in tact except a few small items. Had to remove the side fairings, lower the radiator a couple inches and move the ram air duct forward for clearance. I'll try and do a full write up on the repair and link to it, but for now let me give my .02 cents on this product. Definitely, as others mentioned, use the tap to chase the threads in the blue plastic installer handle. Also had to grind the blue installer down to fit inside my spark plug tube, and taped a small tube of pvc to extend it enough so I could hold it while it was down in the spark plug tube. I thought the product worked pretty well, definitely saved a lot of money compared to a time sert ($250+), or a heli-coil ($125) and still seemed like a really good repair as the bike is running great! Review: This worked fine for my application - This worked fine for my application. I needed to purchase the drill bit separately. Unless the proper sized hole has been drilled beforehand, you will need one too. Be careful to first tap the threads in the inserting tool before you put a coil in it. The first coil I tried got stuck. But after I used the tap to clean out the threads it worked as advertised. ## Features - 100% Made in U.S.A.!

I needed to purchase the drill bit separately. Unless the proper sized hole has been drilled beforehand, you will need one too. Be careful to first tap the threads in the inserting tool before you put a coil in it. The first coil I tried got stuck. But after I used the tap to clean out the threads it worked as advertised. ### ⭐⭐⭐⭐⭐ The Coils in the kit are not the wrong size. Read the instructions! *by J***E on April 2, 2015* This kit worked well for me. I was surprised when I took out one of the coils and tried to thread the M10 bolt into it and it seemed WAY TOO BIG! I saw another review on here where someone said they sent the wrong size, but if you just read the instructions, you have to insert it into the blue piece first. It actually compacts it before you thread it in. I would recommend this product for the price and also for the quality. Remember to use a little locktite before you put the coil in so it doesn't come out later. Used on a 1999 Ducati Monster Engine Cover. --- ## 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://www.desertcart.in/products/18915730-thread-kits-1221-m1010-thread-repair-kit](https://www.desertcart.in/products/18915730-thread-kits-1221-m1010-thread-repair-kit) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-05-03*
