Product Details

The NGK 7240 V-Power spark plug (NGK part number YR55) is a resistor-type replacement spark plug with a copper core center electrode and a standard nickel ground electrode. It is built for dependable ignition, easy installation and long service life in engines that call for the YR55 heat range and configuration.

Key Features:

  • Copper core: The solid copper core improves heat dissipation and conductivity and gives the plug a wide heat range.
  • Cold-rolled threads: These help prevent cross-threading and protect cylinder head threads.
  • Trivalent metal plating: The plating resists corrosion and seizing, so the plug installs and removes more easily.
  • Resistor design: The 5,000 ohm resistance helps suppress radio-frequency interference.

Specifications:

  • NGK stock number: 7240
  • NGK part number: YR55
  • Series: V-Power
  • Thread diameter: 14 mm
  • Hex size: 16 mm
  • Seat type: Tapered
  • Pre-set gap: 0.060 in.
  • Ground electrode: Standard design, nickel
  • Center electrode: Copper core with nickel tip
  • Terminal: Non-removable nut

Cross-references: Autolite 685, Denso T20R-U.

Ordered a K&N air filter that was $10 cheaper than anywhere else online. Got it two days later, too. I'll be buying here again!

Excellent price on the product and shipping! Ordered on Thursday night (after they closed) and they were shipped out Monday!

Easy to find part and order.

First time I've tried these guys. Had trouble getting this product from my normal source (backordered) but Autoplicity shipped quickly and had a better price too! You know I will be back! Thanks!

I searched for a quality automobile battery charger and found the best priced and longest warranty "smart" charger at Autoplicity and one other seller. Autoplicity carried a wider selection of the models offered by the manufacturer.<br> Looking over the website I entered my vehicles into the fields and found quality offerings. It is worth looking at.<br> Ordering was straight forward, shipping began the next day with a tracking number, and the order arrived on time. I bookmarked the website.

Great customer service. Prompt shipment and excellent prices. I will defiantly be ordering from them again. Just wish I would have found them sooner!!

I received my ARP head studs as described and on time with zero problems, and cheaper than anywhere else.Will use again!!!
