Designed with a colder heat range and yttrium-enhanced alloy, it supports performance modifications while extending spark plug life up to 100,000 miles.

## Description

The E3.62 auto spark plug is a 14mm, 0.708” reach plug with a taper seat. E3.62 is the same heat range as E3.54, but has a wider gap. 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: E3.62; 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.

Review: So I purchased a crate motor 2 years ago from jugs automotive when I purchase the engine I purchased AC Delco iridium spark plugs from desertcart after engine installation and spark plug installation I developed a knocking and pinging noise I replaced the knock sensor and of course it already had the new plugs wires cap rotor and everything else under the hood I do know at the time where we get fuel changed the quality of gas for the winter I then started using premium fuel to stop the pinging at low rpm under load . Well well well . I went ahead and bought a set of E3 spark plugs oh my gosh throttle response amazing idle amazing no more pinging and the 5.7 runs amazing hard to believe the E3 changed the engine that much ! Some people say they have snake oil to sell you and e3's are a joke but I'm here to tell you they work phenomenal
Review: desertcart sent me the wrong ones, I bought the right ones from a local brick and mortar. desertcart paid for the return and refunded my money. These are now the 3 set of these I have put in a car. This set went into a 3.1L 175hp Pontiac. Noticeable improvement in throttle response, and top end pull. BUT - don't expect to blown away. Combined with a Thrush baffled muffler, K&N drop in air filter, new OEM coils, and MSD 8.5mm plug wires, I probably netted +10% HP..... More impressive, my combined mileage has improved from 19.5mpg to 23.5mpg. Again, this is the combo of parts that achieved this, not the E3s alone.... For the mileage and meager performance increase, the full combo was well worth $300.... ***UPDATE*** 11.20.2020 I no longer own this car, but felt the need to update with other findings. Not all cars are happy with these. Most recently, a 2004 Grand Cherokee with the non-HO 4.7, responded poorly with rough idle and a top end that just felt off - like peak power started to roll off earlier. They were removed and factory spec copper plugs put back in. My 70 'Cuda was not happy either (340 stroked to 408, MSD distributorless ignition 6LS, Holly Dominator EFI). She has quite a bit of cam and already idles a touch rough. After the E3's she didn't want to idle at all despite attempts to tune the 6LS and Dominator systems to compensate. She was just plain angry. Never even bothered with a test drive. Autolite Platinums were installed. A 2000 Grand Caravan 3.0 v6 also suffered a poor idle, and actually saw an almost 1mpg loss. Autolite Platinums were installed.
