Autolite Copper Core Spark Plugs deliver quick starts, good fuel economy, and smooth acceleration. The copper-glass seal bonds insulator and terminal post center electrode together to ensure full required voltage at spark gap, creating a gas-tight seal that is 100 percent leak-proof. Copper Core spark plugs feature a cold-formed steel shell and precision rolled threads, and a one-piece terminal post that adds strength. The multi-rib insulator reduces the danger of flash-over to prevent misfires, and the resistor reduces radio frequency interference (RFI) and electrode erosion. The full copper core electrode provides better performance in all conditions. Autolite Copper Core plugs are your industry standard.
These copper spark plugs worked well for a while, but I found they didn’t last as long as I hoped. They improved my engine's performance right after installation, but the lifespan left me wanting. Still decent for the price!

Solid performance from Autolite!
I recently replaced my old spark plugs with these Autolite 458 copper ones and I’m impressed. The car starts smoother and feels more responsive. Plus, installation was a breeze for me!

Decent spark plugs for the price
I picked up these Autolite 458 spark plugs for a quick fix in my old truck. They did the job well enough and improved my fuel efficiency a bit. Great for a budget replacement, just don’t expect miracles!

Great fit for my older model!
I bought these Autolite spark plugs for my 2005 sedan, and they fit perfectly. The engine runs way better now, but I wish they came in a 4-pack instead of 1. That would be more convenient for a full replacement!

Not what I expected
I had high hopes for these Autolite spark plugs, but one arrived damaged, which was disappointing. I could still use the other, but it's frustrating to deal with. Might try a different brand next time.
