The Autolite HT15 is an OE-quality platinum spark plug engineered specifically for Ford 4.6L, 5.4L, and 6.8L 3-valve engines. This high-performance plug features a patented design that delivers enhanced durability, improved power output, and reliable ignition through a more compressive seal and optimized heat transfer.

Key Features:

  • Platinum fine wire electrode design for improved fuel efficiency and reduced emissions

  • Patented construction ensures focused ignition energy and consistent performance
  • Direct OE replacement for Ford 3-valve modular engines (4.6L, 5.4L, 6.8L)

This spark plug is designed to meet or exceed original equipment specifications, making it an ideal replacement choice for maintaining optimal engine performance, throttle response, and fuel economy in compatible Ford vehicles.

Great experience

Great experience with autoplicity. Fast shipping. Ordered on 5/31 got bed cover on 6/2. Fit truck perfect.

I was skeptical about Autoplicity since I hadn't heard of them before, and that their price was 12% lower than anyplace else I could find. Plus, I couldn't even find a store around here that carried the X-jack. Plus I got it delivered right This my door fast. You people are Excellent!

Easy shopping

Excellent business and a pleasure to deal with. Lowest prices on the net and great communication between the business and myself. Will purchase from again!

the shipping charges were high, but still cheaper than any place else with free shipping!

Very easy to order, updated regularly on status, great pricing and product
