Replacement Inserts Compatible CAL389 100 Engines Review

The Replacement Inserts Compatible with CAL389 100 Engines are a great addition to any automotive tool kit. Based on my observations, these inserts are made of high-quality materials ensuring durability and longevity .The precision ENGINEERING ensures that the fit is perfect, providing a seamless repair process. The only downside is that the price may be a bit steep for some customers. But overall, these inserts are a must-have for any serious automotive mechanic..

inserts exactly as described. I've used them on two engines for a total of 18 uses. One is currently being renovated to ensure we don't have any issues. As you can see from the photos, Ford did a terrible job with the number of threads holding the spark plugs to the head. These inserts increase the thread depth on the spark plug and in the head itself. These inserts require a significant amount of labor to install but are well worth it. I have no problem reusing them.
