Odd design. But went right in. Truck needed a tune up so obviously got some more power but not sure if that was from the different design. Fuel milage did nothing.I run these plugs in all my cars and bikes.THESE ARE STRONG RUNNING PLUGS. BEST TO USE WITH HIGH PERF IGNITION AS SEEM TO USE MORE JUICE. I UNDERSTAND THEY BURN A BIT OF EXCESS OIL IN THE CYLINDERS.RECOMEND TO A FRIEND.The following products were ordered to pep up an old 1979 Chevrolet C-20 Single Cab Truck with a tired Small Block 305. I bought the old truck for $900.00 and it ran, but needed some fresh air. All of the products listed below were ordered from Amazon and installed recently. Everything listed not only fit perfectly, but also made an immediate and VERY Noticeable improvement in performance and Fuel mileage. Basically, my fuel efficiency increased by 40%. Torque & HP improved drastically, but I have no way of measuring that improvement.K&N 66-1401 X-Stream Top FilterK&N 85-3545 Base PlateK&N E-1650 High Performance Replacement Air Filter 14" Round 3" HeightAllstar Performance ALL26086 1" Air Cleaner Spacer and O-RingFlowtech 50230FLT Purple Hornies 3-Hole Header MufflerHedman 69094 Tork-Step Painted HedderAllstar Performance ALL26086 1" Air Cleaner Spacer and O-RingWeiand 108-4 5" Air Cleaner GasketCFR Performance Chevy/GM Small Block/Big Block 65K HEI DistributorE3 Spark Plugs E3.40, Truck, Van and SUV OEM Replacement Spark PlugEdelbrock 9905 Performer 600 CFM Manual Choke Remanufactured CarburetorAll of the items listed fit and performed as advertised. I Highly recommend any and all of these products. Thanks to the manufacturers and Amazon for breathing new life into my Old Chevy…Five Stars for these products all the way!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!This is the 4th set of these that I've installed in one of my cars. Every time I've put them in I've noticed performance gains the minute I took off in the vehicle. They are exactly as advertised. I notice that my rigs start easier, accelerate better, and do a bit better on gas mileage. My latest installation was on my 87 Chevy 4x4 pickup. First I installed an MSD 6A digital ignition box and the truck ran great. Then I put in the E3s. Wow! My truck runs excellent! Which is saying a lot as it has a 153K miles on it. I've gotten way more improvement out of these plugs than any other plugs I've tried. That includes: Splitfires, Bosch Platinums, and +2s and +4s, and any other conventional plugs I've used. E3s have always worked great for me.I like these little plugs. I’ve put them in several of my vehicles. From an old Aveo to a Chevy C20 big block. They are simple because they require no adjustments. They really are plug and play. You will feel immediate power increase and faster throttle response with these plugs. I highly recommend these for Chevy vehicles.Have been using E.3 plugs for many years, best plugs you can buy, they last at least 5 years easy, and you will see better performance and mileage.These Spark Plugs really work! They are delivering excellent gas mileage in hot or cold weather. Starting is better as well. I have gone ahead and purchased these Plugs for my 4-cycle lawn mower engine, 4-cycle snow blower engine, 2-cycle string trimmer engine, with excellent results in all. Highly recommended! They are made out of conventional materials and yet last forever. They are much cheaper than the Iridium or Platinum types. Check out their web-site and other reviews. You don't even have to worry about gapping these plugs ........ ever.2 Thumbs up!
