Summary: Ford spark plug blowout repair is covered in this article for 4.6, 5.4 & 6.8 liter engines. There are different brand insert repairs available for this Ford spark plug problem, however they are not all as effective and long lasting as the solution we recommend. Many Ford dealers want to charge thousands to replace the cylinder heads, when our repair can be done in the vehicle for a fraction of the cost. We sell some competitive brands like Lisle and Helicoil, however the Horizon made Calvan 38900 (Mount.9200 same w/different labeling) is the best repair system on the market today. We’ve sold hundreds of these, saving Ford owners a ton of money in the process. In the following article we’ll explain why this should be the next and last repair purchased for this particular repair.
