## Questions & Answers

**Q: Are these a one piece plug?**
A: No this is the 2 piece. The HT15 is the one piece. If you use be sure to put anti-seize on the electrode extension. Start at the bottom of the threads and coat it all the way down until about 1/8 of an inch at the bottom. You don't want to get it on the threads because they will tend to back out and you don't want to get it too close to the electrode because it can cause it to foul. I would have gotten the one piece design but when I realized that I ordered the wrong set it was too late. I needed them pretty bad. I changed my fuel filter and bought all new excel coils.

**Q: Does it fit on an Sport Trac 2007 V8?**
A: This spark plug is for the ford 5.4 3valve. But from my experience go back with the motor craft. My truck had severe misfire with these plugs. Hope this helps

**Q: Is the pack one or four spark plugs?**
A: When I ordered my spark plugs, I ordered eight plugs. Looking at the photo provided, it shows 1 large box and 1 smaller box. The smaller box holds 1 spark plug and the larger box holds 4 spark plugs. Thats about as simple as I can explain it.

**Q: Is for mustang 2006 4.6**
A: Yes these are the correct spark plugs for 2006 Mustang 4.6$10.40 each with free shipping from AutoParts USA

## Customer Reviews

### ⭐⭐⭐⭐⭐ Works great
*by T***N on April 18, 2024*

Put them in my ford explorer worked great

### ⭐⭐⭐⭐⭐ Good two piece plug replacement
*by J***S on August 14, 2022*

Recently bought a 2006 Mustang GT that I was having acceleration issues with. Car had 88K miles so I figured it might have the original plugs, but that would mean they were the infamous two-piece Motorcraft plugs that could break when removing. Got the original plugs out and replaced with the HT1s which is an improved one-piece plug. Car’s running great.

### ⭐⭐⭐⭐⭐ Perfect
*by C***E on May 31, 2024*

The Stang is alive again... no more popping or misfiring at take off.
