Good Plug - Great Price
I bought this plug mainly becuase I wanted an Iridium plug that would have the durability, and reliability to match that of the OEM plugs. I spent a lot of time researching various plugs, but when it comes down to it; for a daily driver just about any plug will be fine. What I did like was that between the online savings code with Advance Auto and the mail-in rebate from Autolite, I was able to purchase these for less than $3 a plug. I put the plugs into both a 2002 Lincoln Navigator with the 5.4L and a 2002 Ford Mustang GT with the 4.6L. After a month of driving, both run very smoothly and are performing as expected. These are a good plug at a good price.

Not Pleased
I just installed the Autolite Xtreme Iridium plugs and the 19 yr old nissan 3.0 v6 motor developed a rough idle and drop in performance. So yesterday I reinstalled the old plugs and the engine runs quite abit smoother. Oh well..

Bottom Line No, I would not recommend to a friend
Works for 2014 Ford F-150 STX V8
Anyone who says you must use Motorcraft plugs in these engines is ignorant on how to properly replace spark plugs. In order to do this job correctly and get good results, first make sure to check every individual plug for a proper gap. I found one plug in my 8 that was too tight. This would cause an issue if not resolved. Secondly after replacing the plugs you must reset your computer onboard by pulling the negative off the battery for at least 30 seconds. Failure to do this will make the computer treat the new plugs like the old ones. They are clearly going to act differently. Once you cycle battery power and reconnect the battery, run the truck in park for a minute, in drive for a minute, and then drive around for about 10 miles for the computer to learn the new plug settings. If you don't do these basic things and find your engine is running weird, don't blame the plug manufacturer. You didn't do the maintenance correctly. Sometimes replacing plugs also won't resolve other reasons for rough idling and acceleration like dirty or broken sensors. Know what you're doing.
Bottom Line Yes, I would recommend to a friend

These Don't Cost They Pay
Staff Reviewer -
I installed these in my 1993, 4.0L 6 cylinder, 183K+ Jeep! Thought I was crazy for paying over $6.00 per plug! But it instantly improved my fuel economy from 14.8 MPG to 17.5 MPG. At first I didn't believe it but have been running them for over 6 months and the mileage hasn't fallen off. With gas at $3.40+ per gallon, like I said these didn't cost they pay! Well worth every penny! And the warranty is for 5 years! Why do they sell anything other than these? Or why would you buy anything other than these?
Bottom Line Yes, I would recommend to a friend
decent plug
it is a decent plug my major complait i dropped 3 mpg. If you have a dodge ram i would not recommend this plug. Taking them back and reinstalling E3 dimond fire. By far the best peformance and mpg of any plug i have tryed.
Bottom Line No, I would not recommend to a friend
