    Ok so im looking into changing my plugs and wires. I thought about double platinum AC Delco plugs and MSD wires. Any opinions or comments on my choice??

    For Plugs You would want.....the A/C Delco Iridium Tip Spark Plugs.....and the reason is.......the natural properties of iridium, with a melting point of approximately 700 degrees Celsius higher than platinum, help enable the plug to burn fuel more efficiently and to deliver better performance. As a result, the iridium plugs have a minimum service life of 100,000 miles.

    For Wires the MSD Wires are as Good as it gets....along with......JBA and Taylor.

    The Gap on the A/C Delco Iridium Tip Plugs is.....0.40......They will be Gaped right out of the box.....Check the Gap to be sure......But Do Not attempt to Re-Gap them as the Iridium Tip can be easily Damaged.

    ya be careful when checking gap.... just lightly check it. Its easy to screw up the tips and then your 7 dollar spark plug isnt worth much. I have heard nothing but praise out of the AC delcos.....

    stay away from the NGK iridiums. I bought some last year and I was always told not to gap them. I checked the gap on them and they were huge, like .060 or something like that. I tried them anyway. The truck ran terrible, rough idle. I returned them to advance auto and the guy tried telling be that I had to gap them. Too late they were already out and the stockers are back in. I will be going with the AC delcos when I do it next time.
