Comments about Autolite Double Platinum Spark Plugs:
Changing spark plugs on a sideways V-6 is a daunting task. So, while my upper intake manifold was off I changed all the spark plugs. I think the OEM plugs were still in there! The electrodes were almost gone!
These plugs have performed just as well as the OEM did and I'm very happy with the installation and performance of the entire job.

Q:I need to order some spark plugs I need to get six but it does not say online if they are 1 in a pack or two in a pack can you help please.
A:Hi Tony, great question! I researched on our website and found that this double platinum spark plug is sold individually.
Q:the spark plugs needs gap or not?
A:Yes, the Autolite Double Platinum Spark Plug (Part No. APP646) needs gap. Gap new plugs as recommended in your owner's manual or a Spark Plug Catalog. Use a feeler gauge to measure the gap between the center and ground electrode. The gauge should pass through snugly but easily. If it's too loose or too tight, reset the gap.
