Quality Ignition Part!

Based on my experience, this automotive ignition part is worth every penny. The performance and efficiency of my engine has increased significantly. The build quality and durability of the part are both impressive. However finding the right size for my vehicle was a bit of a challenge. Regardless, the NGK NX91 Premium Spark Plug is a must-have for anyone looking to upgrade their ignition system. .

Pros
  • Provides superior ignition and engine performance
Cons
  • Slightly more expensive than some other spark plugs on the market

Excellent replacement product

Cables match original equipment very well. The longer boot covers on plugs 2, 4 and 6 are not as stiff as the OEM kit. However, I managed to snap them into place without much difficulty. Performance seems excellent as it fixed an issue with my original cable that was installed on a car over 21 years old. Also, the light blue color looked cool.

Pros
  • High temperature (250°+ C / 482°+ F) silicone jacket resists moisture, oil/gasoline and cracking from extreme temperatures
Cons
  • Mostly good, but...
