Product Details

The E3.74 spark plug features E3's patented DiamondFIRE electrode technology designed to increase power, improve fuel efficiency, and reduce emissions. This 14mm spark plug has a 1.000-inch reach with a taper seat, making it compatible with a wide variety of late model vehicles, particularly Ford applications.

Key Features:

  • Patented DiamondFIRE electrode with unique ground wire design
  • Three-leg electrode attachment for superior heat transfer
  • Creates increased turbulence in the combustion chamber for more complete burn
  • Full-size center electrode for optimal performance
  • 14mm thread diameter with 1.000-inch reach and taper seat
  • Proven to reduce fuel consumption and improve hydrocarbon emissions
  • Guaranteed for 5 years or 100,000 miles

The innovative three-leg design secures the DiamondFIRE electrode to the shell, providing excellent heat dissipation while promoting better air/fuel mixture turbulence. This results in more efficient combustion, translating to measurable improvements in engine performance and longevity.

great

Paid for UPS 2nd Day service on Wednesday afternoon... called Autoplicity about lack of shipping info on Thursday AM and was told the system takes 24 hrs to update. On Friday tracking put the shipment in the delivery location at 1:30am. UPS customer service advised they could have refunded shipping cost if I had shipped direct.... not sure how or why I would accomplish the task. UPS advised contacting the shipper to resolve the issue.. really? Product sat in the UPS delivery center until Monday AM and was delivered Monday PM. Product was installed in my tractor Monday evening.... now it has rained every day and I can't cut the field. Question is really, why offer 2 day service at a premium when no one does what they promise... Purchased these bearings at Autoplicity because of the 2 day service..... who dropped the ball? Most on-line retailers shipping options change if and when you are outside guidelines. That wasn't the case here.

What I needed, shipping fees are higher than I expected.

Fast shipping, good products.
