Designed with a 14mm thread and 0.750-inch reach, it fits a broad range of domestic and import vehicles.

## Description

Product Description The E3.64 automotive spark plug is engineered to provide superior performance in a wide range of late-model applications, particularly imports. Designed with a 14mm thread diameter and a 0.750” reach, features a gasket seat and is widely stocked in automotive retail stores. E3 spark plugs are renowned for their innovative DiamondFIRE technology, which includes three legs that securely fasten the DiamondFIRE electrode to the shell, ensuring exceptional heat transfer and creating turbulence within the cylinder. This design maximizes power output, boosts fuel efficiency, and reduces hydrocarbon emissions, making it an ideal choice for long-term engine performance. The spark plug also features a unique ground electrode and full-size center electrode, which enhances ignition reliability and ensures optimal performance for up to five years or 100,000 miles. The patented DiamondFIRE side wire technology promotes a faster, more complete burn, helping to lower fuel consumption while improving combustion efficiency. This technology’s open design generates an edge-to-edge spark path that replenishes the spark zone with fresh fuel/air charges and exposes the flame front more directly to the piston head. This results in smoother acceleration, improved engine power, and reduced carbon monoxide emissions. desertcart.com

Review: No other - E3 really surprised me I own a 25 year old BMW I've used Bosh which is factory recommended and car idles fine with the Bosch but where the E3 really surpassed the other brands is at higher rpm's the E3 will produce a stronger spark say when your cruising the highway at 80 + mph you'll notice a more complete burn of your fuel due to the stronger spark I highly recommend these plugs especially for a high mileage engine and my engine is at 230,000 miles and still runs strong.
Review: I have put these plugs in 3 different vehicles - We have 2 BMWs (650i and a 330ci) and 1 Audi (A6) in the household and I have installed E3s in all of them. First I would like to say that E3 should expand their marketing to include German built cars. My BMW dealership and other BMW specific repair facilities have never heard of them and warned me not to install anything but manufacturer recommended OEM replacement plugs as I would most likely generate a engine misfire or at the very least a check engine light that would cause me to have state inspection problems. None of these things have happened. In fact all three cars have never run better. They have more power and get better mileage. I would recommend E3s to anyone who asks.
