Product Details

The NGK 7909 (stock number 7909, NGK plug number AB-8) Standard spark plug is a conventional nickel-alloy replacement plug with a copper core. It is built to OE-style specifications for dependable ignition performance. It suits applications that originally used standard nickel-alloy plugs, including many powersports and small-engine applications. It is not intended to replace factory precious-metal plugs.

Key Features:

  • Solid copper core center electrode helps draw heat away from the firing tip for better heat transfer
  • Nickel-alloy center and ground electrodes with a standard, non-projected design
  • High-grade alumina silicate ceramic insulator for strength and heat transfer
  • Corrugated insulator ribs help prevent flashover
  • Triple gasket sealing helps prevent combustion gas leakage
  • Trivalent metal plating resists corrosion and seizing for easier installation and removal
  • Cold-rolled threads help prevent cross-threading and cylinder head damage

Specifications:

  • NGK stock number: 7909
  • NGK plug number: AB-8
  • Heat range: 8
  • Thread size: M18 x 1.5 (18 mm)
  • Thread reach: 12 mm (0.472 in.)
  • Seat type: Flat, with crush gasket
  • Hex size: 13/16 in. (21 mm)
  • Pre-set gap: 0.028 in. (0.7 mm)
  • Terminal: Removable nut
  • Resistor: No (non-resistor)
  • Ground electrodes: 1
  • Recommended torque with gasket: 25.3-32.5 lb-ft for cast iron heads, 25.3-28.9 lb-ft for aluminum heads

NGK is a leading OE spark plug supplier. This standard-series plug is a proven, cost-effective option for routine ignition maintenance. Check the gap against your engine's specification before installing.

Found the parts I needed at a GREAT price, hope the next day air shipping is prompt..

Great transaction

Fast

Nice and easy!!

:)

Lovely

Received them faster than I expected. I wanted to get matching tires for two I already had, which are an odd size, and Autoplicity had 'em in stock. Exact Size & Exact Brand! Not to mention they were priced about 20% LESS than then next best price I found. I might order 2 more soon for the Spring! Thanks Little Frank - L.I. NY

The box was ripped

Had what I needed

great pricing and received my purchase quickly. the box was a bit torn up, but the contents were fine.

Easy ordering

Lowest price I can find! Sent tracking number via FedEx without trouble! Would recommend!

I'm a stickler for finding the best prices on my purchases, while also making sure that the products I buy are legit and not some cheapo knock-offs.<br>I did my homework on the Clutch Stage 2 kit I wanted for my Spec V and found that Autoplicity had the best price anywhere, even a spot where I had 10% off came out to be more expensive.<br><br>I received my Clutch Stage 2 clutch kit pretty quickly (about 1 week) and everything was as expected.<br><br>Overall I would rate Autoplicity a perfect 10, although I did not have to contact their customer service or initiate a return, so the '10' would be on product selection, communication, website experience, and overall feeling that I got the best deal out there.<br><br>Thanks!

Autoplicity had the lowest price online for the product I needed. I will definitely buy from them again.

hope works out

Great website and the ordering was easy too. I like the way they show the full price including shipping and tax. Got the confirmation immediately and the shipment notification the next business day. <br>

Very easy to order on line and excellent communication, very good price.

Great seller! good communication between autoplicity and buyer!<br>Also very quick to process and send out product! Got order within 6 days standard shipping! Will purchase from again!!
