Product Details

The Bosch 7431 is an OE Fine Wire Double Iridium spark plug engineered to deliver exceptional performance and extended service life for modern gasoline engines. This premium spark plug features both an ultra-fine 0.6mm iridium center electrode and an iridium ground electrode inlay, representing advanced original equipment spark plug technology.

Key Features:

  • Double iridium electrodes provide up to 4 times longer life compared to standard copper spark plugs
  • 360-degree laser welded ultra-fine wire iridium firing pin delivers superior ignitability and reduces voltage requirements by up to 24%
  • Tapered ground electrode design minimizes flame shrouding for improved combustion and enhanced engine performance
  • Copper core electrode provides broader heat range to resist pre-ignition and fouling
  • Nickel-plated rolled threads provide corrosion resistance and eliminate the need for anti-seize during installation
  • Pre-gapped at the factory at 0.031 inches for quick, easy installation right out of the box
  • OE-matched spark position ensures compatibility with Gasoline Direct Injection (GDI) engines
  • Ribbed insulator design prevents flashover for reliable performance

Specifications:

  • Thread Size: 12mm with 1.25mm pitch
  • Reach: 26.5mm (1.043 inches)
  • Heat Range: 6
  • Seat Type: Gasket (flat seat)
  • Hex Size: 5/8 inch (16mm)
  • Gap: 0.031 inches (0.8mm)

I liked the selection of parts available along with your fitment check for my vehicle.

Easy to use, very fast checkout

Great experience fast and user friendly

Quick and easy!

cheaper the Jegs and Summit looks like i will be shopping here more

Great to link with Amazon-made ordering much simpler and easier. Company responded to inquiry quickly and accommodated my request.

quick and easy,good price.

Glad I found Autoplicity.com. Big potential...<br><br>Ordered parts on Friday, missed 1st delivery attempt to office yesterday (Weds), but received today (Thurs). Little slow on the shipping, but not in a rush for these parts. We typically receive UPS pkgs in 1-2 bus days from Chicago suburbs to Metro Detroit. This took a bit longer, but again - it was not a problem & well worth the savings.<br> <br>Wish web-site would actually separate items for just my car vs all vehicle matches. Finding what I wanted was very difficult, but I'm very pleased with pricing & follow through. I've been back on Autoplicity 2 times now looking for add'tl parts for another vehicle, but have yet to locate them amongst the 100's - even 1000's of results that do not match. If finding them were easier & these add'tl items offer similar savings, I would have spent hundreds more by now. <br><br>If this is a new company, hopefully they can correct the advanced search option as well. Entering a part by vendor name should net results when the brand is listed on the home page & can be found in general queries. Even when I entered the part # for an item it shows no results, but again - searching several dozen pages, I am able to find the same part #. The savings were worth the headache it took to find the brake pads for my BMW, so I won't give up just yet. <br><br>Thanks Autoplicity! Here's to a potentially great future!!
