2005-2007 4.6/5.4 3V HT0 Spark Plugs
JDM Engineering exclusively uses the Autolite HTO plugs on all its 2005-2007 Supercharged Mustang and 3V F-150 Trucks. These Plugs are one heat range colder than the factory plugs.
JDM offers them pre-gapped @ .030, because these plugs requires a special tool for gapping.

Accurately Pre-Gapped & Ready to Install
I've been buying the pregapped Autolite HTO's from JDM since 2010. The .030 pregap is perfect for my 2006 Saleen SC. I like having the confidence that the pregap is accurate & specific to my car. Then I drop them off at my local mechanic to install.
