Product DescriptionThe E3.53 auto spark plug is a 14mm, .708 reach plug with a taper seat. It fits domestic applications, and is widely available in automotive retail stores. E3 automotive plugs have three legs securing the DiamondFIRE electrode to the shell. This allows for excellent heat transfer, and helps to create more turbulence in the cylinder. The patented DiamondFIRE side wire is proven to increase power, reduce fuel consumption and improve hydrocarbon emissions in long-term use. The unique ground electrode and full-size center electrode also provides optimal performance for a guaranteed five years or 100,000 miles. Part Number: E3.53; Resistor: Resistor; Hex Size: 5/8''; Thread Reach: 0.708''; Thread Diameter: 14mm; Seat: Taper; Tip/Gap: DiamondFIRE Fixed Gap Cannot Be Adjusted. Our unique DiamondFIRE open design forces air gap discharges, creating the preferred edge-to-edge spark path. The design allows replenishment of the spark zone with a fresh fuel/air charge, and exposes the flame front more directly to the piston head than other plug designs. This distinctive spark plug design has proven to simultaneously increase engine power output, reduce gasoline consumption, decrease hydrocarbon and carbon monoxide emissions from the engine, and materially extend the life of the spark plug. Our lawn and garden spark plugs help engines operate more efficiently with a faster and smoother acceleration.Amazon.com
I had high hopes for these spark plugs, but after a month they don't seem to be delivering the performance they promised. I’m not sure if it’s just my car or these plugs specifically. The 0.708 reach fit well, but I might try a different brand next time.

Excellent spark plug choice
Installed the E3 53 plugs in my 2015 sedan, and I'm impressed! The engine is more responsive and I can feel the extra power. The tapered seat makes installation straightforward. Definitely worth the purchase.

Good but packaging could improve
These E3 spark plugs seem solid and the engine runs better after the install. However, the packaging was a bit flimsy and one plug had minor scuff marks. Still, they work well, so I'm not too upset.

Great performance boost!
I replaced the old spark plugs in my car with the E3 53s and wow, what a difference! The DiamondFire technology really helps with fuel efficiency and I noticed my engine running smoother. Plus, the 14mm thread diameter fit perfectly.

Solid investment for my truck
I chose the E3 spark plugs for my truck based on recommendations, and I'm happy with them. The DiamondFire technology seems to have improved my fuel economy and starting performance. I'll be telling my friends about these!
