Great Spark Plugs
Been using these spark plugs for three years now and the car is still running great! We saved a ton on money by going through this seller and Amazon. They were very easy to install.

Good plugs!
These are fine spark plugs, and are iridium, for the price of inexpensive platinum plugs. They came gapped at exactly .044, which is the specification for the car that they were installed in. Normally I would use NGK or Denso in a Japanese car, but these are much more reasonably priced, are excellent quality and should last for a very long time.

Decent spark plugs that perform well. I have everything used autolite spark plugs on many many makes/models of vehicles and have yet to have an issue out of the box or shortly after installing so I will continue to use them.

Not dependable
Garbage didn't even last 2000 miles. Changed a few months ago and had to change them with another brand. The ceramic part cracked and started causing a misfire. Would not recommend.

Fantastic spark plugs
They can't very fast, exactly what was ordered. The spark plugs worked perfectly in the vehicle. Absolutely improved the performance and fuel economy. I have used in 2006 Honda pilot and 2006 Honda civic.

Cheaper sparkplugs.
These spark plugs were an add-on item and I was tempted to buy the whole lot. So far my Honda cars start without issue and I've seen some improvement with gas and engine running. These are cheaper for old cars like mine.

Works well in small engines also.
Put a pair of these into a B&S Vanguard 35HP. So far they are running fine. Nice tan color on the plug after a few hours of use.
