      Good seller. Had an issue with tracking that wouldn’t update and it seemed like the seller printed a label but wasn’t actually dropping off the package. After some short tempered messages from me, seller stayed professional and explained to me that USPS will pick up bulk items and just never update them until they’re out for delivery, and that’s exactly what happened. Shipping was super duper fast, and seller had great communication. Item was packaged great, and was the best value too.

      Ordered on a Saturday with a delivery date of Tues - Thurs. Told the seller I desperately needed them by the weekend because we all know the best price is usually the slowest delivery. Not here. They were on my doorstep three days later first thing Tuesday morning. Fair price and OUTSTANDING service. Thank you!!!

      My LT Headers came in right on time! Everything went smoothly from start to delivery! Kept me informed on shipment and the biggest part is They Came Thru With The Product. A lot of these other company’s will take your money and not have the item assuming the builder has them in stock then your stuck waiting 12-16 weeks for what you payed for!!!! I can’t thank you guys enough for being straight up and coming thru like you advertised.. I’ll definitely be purchasing from these guys again……

      1953 Hemi V8 Engine Vintage Spark Plugs

      I have a 1953 Chrysler Hemi V8 enginethat my Father and I put into a 1940 Ford Pickup, in 1958.. I have been buying the wrong spark plugs for my engine for over 15 years! I remember my Father showing me (30 years ago), that the original plugs did not use a gasket, like all other plugs use. I never could find the correct type, so I continued to buy the ones available. The Autolite AR82 Spark Plug do NOT use a gasket, therefore allowing the spark plug to go deeper into the Hemi cylinder heads, providing more horsepower, and better gas mileage. Thank you for the NOS vintage Hemi plugs! They work the way they were supposed to.

      I have a mildly modified sbc, in an old El Camino. I didn't pick up 100 horse power or anything like that, but it DEFINITELY has more power, and a smoother idle. They are pricey, but still a good value.

    • Greatest spark plugs on the planet

      I've used e3s on everything from my toyotas, chevrolet to lawn mowers. They are the most dependable, cleanest burning gas saving plugs money can buy. Never had a bad one.

    • I have the confidence these plugs will help my fuel econimy

      Five Star product: I installed these E3.40 plugs in my 1990 Ford pickup and have noticed an incredible noticeable ower increase, along with the 10.5 racing plug wires and new cap and rotor kit. I am hopeful they will also give me better fuel mileage also .

    • Will not change your world but will pep up your engine.

      I can't vouch for all the claims made about these but I can tell you they made a small noticeable difference in my engine, all for the better.
