Product Details

The NGK BR8ES spark plug (part number 5422) is a standard copper core spark plug trusted by automotive, motorcycle, and marine engine manufacturers worldwide. This 4-pack features NGK's proven design that delivers reliable starts, consistent performance, and extended service life across a wide range of applications.

Key Features:

  • Solid copper core for superior heat dissipation and conductivity
  • Triple gasket sealing process eliminates combustion gas leakage past the shell
  • 99% highly pure alumina silicate ceramic insulator for superior strength and heat transfer
  • Corrugated ribs on insulator prevent flashover and misfires
  • Cold rolled threads prevent damage to cylinder head during installation
  • Trivalent plating with silver chromate and zinc for maximum corrosion resistance
  • Exclusive electrode design ensures optimal spark and combustion efficiency

The BR8ES is a heat range 8 spark plug commonly used in two-stroke and four-stroke engines requiring a colder heat range. NGK's copper core construction provides faster heat dissipation from the firing tip compared to standard nickel alloy electrodes, making it ideal for high-performance and racing applications. Sold in standard 4-piece packs only.

My name is Doug Raber and I tell you the truth when I say autoplicity is a great site to shop for auto parts. The prices are low and the customer service is excellent.

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

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!

Quick easy

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!!

Great price, fast shipping and the items was correct. A perfect transaction. Thank you!

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