    • Good price and quality
Part Number: 401 Style: 1
I always use copper plugs in my 99 Chevy and have bought these for my last two. They fit right, each plug has so far been gapped properly and the performance of my old vortec is still smooth and sounds great when I get on it. Good value

    • Cheaply made.
Part Number: 401 Style: 1
Bought 10, received 9. Needed 8 to replace the plugs in my engine. One of the 8 didn’t thread into the cylinder head. Determined poor thread quality. You get what you pay for. Buy an extra just in case one doesn’t thread properly.

Part Number: 401 Style: 1
For me, this exact spark plug at the store was a little more difficult than anticipated. Luckily, I was able to find them on Amazon (as usual) and with the price being right. The threading on the plug is a perfect cut and installation was a breeze. Spark was immediate and I am back to mowing with no issues. I would recommend. ... show more
