Product Details

The Bosch 7538 (WR11E0) is a copper core spark plug with nickel electrode designed specifically for small engines used in lawn mowers, snow blowers, and outdoor power equipment. This reliable replacement spark plug delivers consistent ignition performance for Briggs & Stratton, Kohler, and other popular small engine brands.

Advanced Electrode Design:

  • Yttrium-enhanced center electrode with copper core for superior heat dissipation and extended service life
  • Nickel chromium ground electrode provides reliable cold weather starts and improved ignitability
  • Standard 2.5mm non-projected center electrode design

Key Features:

  • Metal glass fused 10k Ohm resistor provides maximum electromagnetic interference suppression
  • Angular 5-rib insulator design prevents flashover and current leakage
  • Nickel-plated rolled threads offer anti-seize properties and corrosion protection for easy installation and removal
  • Pre-gapped to 0.031 inches (0.8mm) for quick installation

Technical Specifications:

  • Thread diameter: 14mm with 1.25mm pitch
  • Reach: 9.5mm (3/8 inch)
  • Hex size: 13/16 inch (21mm)
  • Seat type: Gasket
  • Terminal type: Removable nut
  • Resistor: Yes (10k Ohm)

Installation Torque Specifications:

  • Cast iron heads: 15-18 lb-ft
  • Aluminum heads: 11-14 lb-ft

This Bosch OEM-quality spark plug crosses to Champion J19LM/RJ19LM, NGK B2LM/BR2LM, Briggs & Stratton 796112S, and Autolite 458. The copper core design provides excellent heat transfer to resist pre-ignition and fouling, while the nickel electrodes deliver longer service life than standard copper plugs.

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.

Fast shipping, great price, product was somewhat hard to install but got it done, love the outcome of it. Overall happy.

Easy peasy lemon squeezie

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 :(
