These tapered seat-style spark plug non-foulers are designed to install onto the terminal end of your spark plugs. In doing so, these spark plug non-foulers act as barriers between oil or fuel vapors to prevent residue build-up. The result is optimal spark plug performance and service life.

      Heavy-Duty Build Quality. These tapered seat-style spark plug non-foulers are made from high-quality steel, making them extremely durable. Furthermore, these spark plug non-foulers are machine-formed to include a 14mm thread pitch and a tapered seat design, offering an exact fit when mounted onto your spark plugs. Finally, these non-foulers feature a silver metallic finish for a stunning look.

      Trouble-Free Install Procedure. Installing these tapered seat-style spark plug non-foulers is a trouble-free process that won’t require any modifications to your vehicle. Simply thread your spark plug into these non-foulers and reinstall the assembled piece back into your engine. Please note that these components will require cleaning from time to time.
