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..

Are these plugs pre gaped?
Verified Reply - Solomon
Hi Thomas, happy to help you! This Autolite Iridium Iridium XP Spark Plug (Part # XP3924) has a pre-gap size of .045"-inch. All the spark plugs are pre-gapped from the factory, the fact remains that the gap must be adjusted for the vehicle that the spark plug is intended for. Those with modified engines must remember that a modified engine with higher compression or forced induction will typically require a smaller gap settings.
Are these considered short plugs and what's the length?
Verified Reply - Steve
No, David, this Autolite Iridium Iridium XP Spark Plug (Part # XP3924) is not a short spark plug, it has a thread reach of 0.75"- inches.
How do I get the rebate in the mail? What do I have to do?
