Strong start
Once gapped correctly they got rid of the shake in the car. They fit a 2004 Camry 2.4ltr 4 cylinder.

Perfect for my Application
These are great spark plugs at a super low price. The work very well in a First Gen Neon. As always, make sure to check spark plug gap before installing. 5 stars, I would buy again!!

cheap spark plugs
cheap plugs these are not quality plugs. These are for the old work truck or lawnmower or whatever. They are so cheap the washers are not installed. You have to thread them on your self. I use these on all the old junkers I work on.If I am working on a new car I use better plugs.

Good temp range, Very strong spark, AWESOME PLUGS FOR BOOSTED CARS
If you have a turbocharged or supercharged car and if you're pushing high boost, USE THESE. I purchased these for my 1991 Toyota Supra because I decided to peak at 30Psi of boost, and all the boost was blowing out the spark with my old plugs after about 4.5k-5k RPM. I switched over to the Autolite Copppers and my car started freely revving all the way to redline at full boost without breaking up in the top end. If you want a good performance spark plug for your boosted car, I've found these have an awesome heat range suitable for relatively high boost. I HIGHLY RECOMMEND THESE IF YOUR GREEDY WITH YOUR BOOST LIKE ME.
