Review: Working as expected. - They arrived quickly as expected and packed nicely. They fit perfectly and are working as expected. Review: Good two piece plug replacement - 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. ## Features - Platinum fine wire tip provides improved fuel efficiency, lower emissions and improved horsepower with virtually no gap erosion - Patented, OE Design provides consistent optimal performance - One-piece ground shield strap for improved heat transfer - High Strength Steel technology to make replacement easy with special socket tool - Designed specifically for Ford 4.6L, 5.4L and 6.8L 3-valve engines ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0085KQAR4 | | Automotive Fit Type | Vehicle Specific Fit | | Best Sellers Rank | #730,967 in Automotive ( See Top 100 in Automotive ) #3,995 in Automotive Replacement Spark Plugs | | Brand | Autolite Iridium Ultra | | Core Material | Platinum | | Customer Reviews | 4.1 4.1 out of 5 stars (160) | | Date First Available | January 7, 2016 | | Exterior | Polished | | Global Trade Identification Number | 00009100043962 | | Item Weight | 7 ounces | | Item model number | HT1-4PK | | Manufacturer | FRAM | | Manufacturer Part Number | HT1-4PK | | Model | Platinum High Thread Spark Plug | | Position | Front, Rear | | Product Dimensions | 3.65 x 4.12 x 1.03 inches | | Thread Size | 5/8" | | Top Material Type | Alloy Steel | | UPC | 009100043962 | | Vehicle Service Type | Car | ## Product Details - **Brand:** Autolite Iridium Ultra - **Core Material:** Platinum - **Thread Size:** 5/8" - **Top Material Type:** Alloy Steel - **Vehicle Service Type:** Car ## Images ![Autolite HT1-4PK HT1 Platinum High Thread Spark Plug, Pack of 4 - Image 1](https://m.media-amazon.com/images/I/71EmG09JU1L.jpg) ![Autolite HT1-4PK HT1 Platinum High Thread Spark Plug, Pack of 4 - Image 2](https://m.media-amazon.com/images/I/41xMeefs95L.jpg) ![Autolite HT1-4PK HT1 Platinum High Thread Spark Plug, Pack of 4 - Image 3](https://m.media-amazon.com/images/I/71VORpSUDQL.jpg) ![Autolite HT1-4PK HT1 Platinum High Thread Spark Plug, Pack of 4 - Image 4](https://m.media-amazon.com/images/I/717gW-wp7HL.jpg) ![Autolite HT1-4PK HT1 Platinum High Thread Spark Plug, Pack of 4 - Image 5](https://m.media-amazon.com/images/I/71Jo61loCbL.jpg) ## Available Options This product comes in different **Number Of Items** options. ## 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 ### ⭐⭐⭐⭐⭐ Working as expected. *by D***N on October 27, 2025* They arrived quickly as expected and packed nicely.

I strongly recommend use a really good penetrating oil on a warm engine spray the penetrating oil let set for at least a 30 minutes. do not force the plugs out work slow and just loosen a little at a time then tighten them keep doing that till the plug comes out. Invest in the plug socket made for a ford. they are cheap enough.. ## Frequently Bought Together - Autolite HT1-4PK HT1 Platinum High Thread Spark Plug, Pack of 4 - ENA Set of 8 Straight Boot Ignition Coil Pack Compatible with Ford Lincoln Expedition Explorer F-150 Super Duty Mustang Mountaineer 4.6l 5.4l 6.8l Replacement for DG511 C1541 FD508 - Permatex 22058 Dielectric Tune-Up Grease, 3oz. - High Performance Dielectric Grease Used To Protect Terminals, Spark Plugs, Wiring And Other Electrical Connections Against Salt, Dirt, And Corrosion --- ## 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.id/products/93575002-autolite-ht1-4pk-ht1-platinum-high-thread-spark-plug-pack](https://www.desertcart.id/products/93575002-autolite-ht1-4pk-ht1-platinum-high-thread-spark-plug-pack) --- *Product available on Desertcart Indonesia* *Store origin: ID* *Last updated: 2026-05-11*
