Product Details

The NGK 2687 Laser Iridium Spark Plug (NGK part number FR6EI) is a resistor-type iridium spark plug with a fine-wire center electrode. It is built for long service life and a stable spark.

Key Features:

  • Laser-welded fine-wire iridium center electrode (0.6 mm) for durability and consistent ignitability
  • Platinum ground electrode for extended electrode life
  • Copper core helps draw heat away from the tip
  • Triple seals help prevent combustion leakage
  • Built-in 5k ohm resistor helps suppress radio-frequency interference

  • Thread diameter: 14 mm

  • Reach: 19 mm (3/4 in)
  • Hex size: 5/8 in (16 mm)
  • Seat type: Gasket
  • Terminal type: Solid
  • Heat range: 6
  • Gap: 0.031 in (0.8 mm)
  • Center electrode: Iridium, fine wire, projected
  • Ground electrode: Platinum
  • Resistor: Yes, 5k ohm
  • Torque: 18-25.3 lb-ft in cast iron heads; 18-21.6 lb-ft in aluminum heads

Cross-references: Mitsubishi MN163236, Bosch F6DTC1, DENSO 4504, 4702, IK20TT and PK20TT.

This spark plug is a direct-fit replacement that helps with reliable starts, smooth idle and efficient combustion. Check the gap before installation and tighten to the torque specification for your cylinder head material.

first time ive order from here and my experience was great! shipping was crazy fast. and they had the best price shipped on the 2jz arp head stud set i could find. also how on their site they actually list if they have the part in stock and how many which is very helpful. ive payed for parts to find out the vender didn't even have them available. which lead to more down time. and we all hate down time :)

Found what I was looking for quick and easy.

I ordered an Optima battery for my truck after I did a Google search for the battery. Autoplicity was the cheapest on the Web. Even cheaper then eBay. They got me hooked. Thanks Autoplicity

Best price on the internet. A lot cheaper than amazon, so I was pretty surprised.

This is the first time I've ordered from Autoplicity. I found they had the best price on the item I was looking for and decided to try them. I ordered this item yesterday(Sunday) and was just informed that it shipped. That is quick. I am pleased with their customer service and will use them as my first source.

Ordered a CTEK charger. Great price, and recieved it in 3 days. Very pleased.

I ordered a Flowmaster cat back system for my 2012 F-150. The order arrived the day they said it would and the product came at a fair price. Well done.

Excellent customer service. Treated me very well. Issued a refund, no problem. Thank you!!
