Fantastic ignition upgrade

When I tried this automotive product I was amazed at the instant improvement in my car's performance. The Spectra Premium C 511 Coil Plug added better acceleration, smoother idling, and a noticeable increase in horsepower.It was an easy installation and fit perfectly into my vehicle. The only downside is that it's slightly more expensive than other coil plugs on the market, but the improvement in performance is worth the extra cost. Overall, i highly recommend this product to any car enthusiast

Pros
  • Improved performance, easy installation, perfect fit
Cons
  • Slightly more expensive than other options

Terrible quality, damaged my car

Using this automotive product, our team found that it caused severe damage to the ignition system in our car.The plug didn't fit properly AND caused misfires and rough idling. We had to take our vehicle to a mechanic to get it fixed and ended up spending more money than we saved. The only positive thing we could say is that the item arrived quickly. We would not recommend using this product..

Pros
  • Durable and long-lasting
Cons
  • May cause compatibility issues with certain vehicle models

A good rubber boot does not fall off its end.

The broken rubber boot came loose and stayed on the spark plug and I caught it removing so I could remove the spark plug with a wrench.

Pros
  • Pretty package
Cons
  • I don't remember
