Product Details

The Bosch 7909 Super Plus is a high-performance copper core spark plug engineered with advanced yttrium-enhanced nickel center electrode technology. This heavy-duty construction delivers superior reliability and durability, offering up to 50% longer service life compared to standard copper spark plugs.

Key Features:

  • Heavy-duty yttrium-enhanced nickel-copper center electrode provides exceptional resistance to spark erosion and extended service life
  • Copper core design delivers broader heat range to effectively resist pre-ignition and deposit build-up
  • Tapered V-profile nickel chromium ground electrode improves cold weather starting performance and increases fuel ignitability
  • Angular five-rib insulator design prevents misfire caused by flashover and current leakage
  • Nickel-plated rolled threads offer complete anti-seize and corrosion protection, eliminating the need for additional anti-seize compound during installation
  • Metal glass fused resistor maximizes interference suppression for reliable performance

Technical Specifications:

  • Thread Size: 14mm
  • Thread Pitch: 1.25mm
  • Reach: 19mm (3/4")
  • Hex Size: 13/16" (21mm)
  • Seat Type: Gasket
  • Gap: 0.031" (0.8mm)
  • Resistor Value: 6K Ohm
  • Terminal Type: Removable Nut

This spark plug represents Bosch's proven racing technology adapted for street use, making it the longest-lasting copper core spark plug available on the market. The removable terminal nut provides installation flexibility, and the precision-engineered design ensures consistent performance across a wide range of operating conditions.

Easy ordering process! Well designed site!

Ordered two oxygen sensors but only one was shipped even though two were listed on the packing slip. I called customer service. A second sensor arrived two days later.

Fast delivery easy ordering

Low prices and great products, thanks!

Great product & service. Install of purchase in spring as the vehicle is stored for the winter. Many thanks Paul--The Capt.

Springs came in on time, and seem to be great quality so far!

The best price on what I was looking for and fairly fast to get it shipped out considering it was drop shipped directly from the manufacturer. Autoplicity has a huge selection and I will definitely be back when ever I need other automotive parts.

Found Autoplicity through price searching. Best price, easy to navigate site, quick service. Bookedmarked for future use!

I ordered the HuskyLiners 98891 Floor Liners for my 2012 Hyundai Elantra on 5/29, received them 5/31. Order #15417. Apparently they have warehouses all over the country to ensure quick delivery. They had the best price on the net. Item arrived in perfect condition. <br><br>Their website needs a little work because I found the item thru Google and not directly from their website. You also can't edit your cart unless you register first which was annoying. Items could use product descriptions - you have to get info from the manufacturer's site. The real-time inventory was a plus.<br><br>Deducted a star because their website needs work.

Thanks for providing a cost effective, reasonable shipping, and fair alternative to high priced on line vendors!

Product is great! Price is perfect! Shipping was slow.... Guess thats what i get for saving some money. Oh well! Ordered 3/25/12 and received 4/5/12 :(
