            Comments about Autolite Xp (Xtreme Performance) Iridium Enhanced Fine Wire Spark Plug:

            I have a 2005 Dodge Magnum R/T 5.7L HEMI. OEM plugs are Champion standard electrode..."change every 30,000 miles". Sorry, but I don't have time for that. I put 25,000+ miles or 2.5 hours/6 days a week. So, my point is I need something that will go more than 2 years on my car before I have to change it. Why? Because the awesome HEMI production team wanted 2 spark plugs per cylinder...so NOT 8 plugs but 16. I don't want to change spark plugs every year, bottom line. So I go with a minimum double platinum, or like this plug, iridium. Iridium is the second-densest element (after osmium) and is the most corrosion-resistant metal...on the planet! So I like it HARD, and NON-corrosive. And you should too ;) At least I think so!

                Installed these on two vehicles:
                2004 Saturn VUE 2.2 at @ 130k Miles (Mother in-law's).
                2006 Saturn ION3 2.4 at @ 99k Miles (My wife's car).
                -Driven 1 week:
                The VUE sounded much better right away and it sure has power. Definitely needed the change... it still had the original plugs which looked fine for that many miles.
                -Driven 2 weeks:
                The ION did not sound different at startup, but I really noticed the difference on the highway on-ramps.

                We may not see an improvement in gas mileage because we are enjoying the extra power from that little engine. It will take some time to see a real improvement.
                So far we have not seen a decrease in gas mileage, and that is a major PLUS.
                Average of 26mpg driving the north side of the Baltimore 695 Beltway during the rush hour parking lot.
                ----
                I hope that helps.

                My car was a little sluggish during acceleration at certain speeds. I replaced the old plugs with cheaper plugs and no change. I replaced the cheaper plugs with these and noticed and increase in response and no more sluggishness. It's been a month and car is still running great.

                          A:

                          Great question Laugy. The 2004 Dodge Ram 1500 with the 5.7L Hemi most likely came originally with Champion or NGK Copper Core spark plugs. These iridium plugs meet OE specifications to run in your vehicle. The iridium material should allow the plugs to last around twice as long as the original plugs if not more. The gap on these plugs is .045 and they are pre-gapped.

                          Hi Kevin, this Autolite Xp (Xtreme Performance) Iridium Enhanced Fine Wire Spark Plug - Part No. XP5263 was pre-gapped at 0.050 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 (to ensure ignitability in these denser air/fuel mixtures). As a rule, the more power you are making, the smaller the gap you will need.

                          Yes, there are a few high resistance spark plugs which are not recommended for a vintage Ford 289 small block engine. The Autolite Xp (Xtreme Performance) Iridium Enhanced Fine Wire Spark Plug - Part No. XP5263 is not compatible with this engine. Instead I would recommend the Autolite Professional Series Ignition Wireset - Part No. 96205 which is compatible with a Ford 289 small block.
