Product Details

The Autolite AP666 Platinum Spark Plug is engineered with a platinum center electrode firing tip that provides improved performance and increased durability, making it an excellent choice for a wide range of automotive applications. The necked-down center electrode fires quicker, cleaner, and with less voltage for easier starts, quicker acceleration, and improved fuel economy.

Key Features:

  • Platinum firing tip prevents gap erosion for longer service life
  • High nickel alloy side electrode maintains precision gap and assures virtually no gap erosion
  • Copper core improves resistance to fouling
  • High alumina ceramic insulator provides thermal conductivity and superior insulation for increased strength
  • Multi-rib insulator prevents flash-over
  • Nickel-plated shell is corrosion resistant for increased durability and extended life
  • Built-in resistor (4k Ohm) for reduced electrical interference

Specifications:

  • Thread Size: 14mm x 1.25mm pitch
  • Reach: 9.5mm (3/8")
  • Gap: 0.059" (1.5mm) factory preset
  • Hex Size: 5/8" (16mm)
  • Seat Type: Tapered
  • Heat Range: 5
  • Torque Specs: 7-15 lb-ft (cast iron and aluminum)

The platinum design delivers quicker firing and smoother starts for better acceleration and improved fuel efficiency. This single platinum spark plug offers reliable ignition performance with reduced misfires and exceptional durability. Sold individually.

Very easy and smooth, great experience.

Great to order via Amazon; don't need to remember another account and password.

Definitely the best price online by far! And the option to check out using Amazon is an added bonus. This will be my first stop for any future needs.

I chose Autoplicity because they offered the best price on a specific part/tool I was looking for. Even with shipping cost, the total came out to below other online retailers (Amazon, etc.). My product shipped within the day and I am eagerly awaiting it!

I bought my horn at Autoplicity because they by far had the best price. So far there service has been nothing short of excellent.

Went Smoothly

great place to order honda parts from ! i will definitely use this siye in the future

Finding the part, and ordering it was great. But UPS dropped the otherwise phenomenal ball... Ordered the item on Wednesday... got it the next MONDAY. I ordered it Second Day Air. Then I find out, "Oh, it's Second BUSINESS Day Air... we don't work

good so far

Order 18232. Everything came quicker than expected! Packed well and in excellent condition. Definitely recommended. Already did to one of my friends looking for parts.

well so far

No problems ordering a leak down tester from Autoplicity which had the lowest price and reasonable shipping charges. The item was well packaged and I would buy from them again.

Lowest price I could find on the internet. They do what they say. Shipped promptly with UPS tracking no. sent by email. Would recommend.<br>
