Autolite Iridium XP Automotive Replacement Spark Plug, XP5224 (1 Pack)

They work good so far. What is great is ordering spark plugs on Amazon comes out way cheaper than buying from a brick and mortar auto part store.

I bought these spark plugs for my 2015 Jeep Compass Sport 2WD 2.0L. Since then, I’ve found out that the Compass/Patriot like the NKG copper plugs the best for gas mileage and performance. However, these have worked well so far and I haven’t had any problems with misfiring or low gas mileage. I’m going to try the NKG on my next spark plug change, so I’ll update this review if I find the mileage is better or worse with the OEM ones. As I said, they’ve worked well so far in my 2015 Compass. My gas mileage around town is pretty low, but on the highway I get up to 29-30 mpg pretty regularly.

This plug was offered at a very good price and was highly rated. It worked perfectly for my 2009 CR-V. I’ve noticed an increase in gas mileage. Would buy it again in 100K miles.

Fair price quick delivery

Price was good. Packaging was not. Plugs came in an envelope and 2 were out of their package rattling around.

Perfect spark plugs, just like oem

Edit: I have completely rewritten the post that I previously had because no one seemed to like the wording of my story. I will be as unbiased as possible.About 3 years ago, I bought a set of 4 autolite iridium XP spark plugs for my 1998 Honda Civic EX. I had read about iridium plugs helping power and economy, and Autolite was having a special $2 off per plug deal, so I decided to buy these plugs. My car typically runs NGK V-Power copper spark plugs, OEM recommended.I used these plugs in conjunction with some new Bosch Plug Wires.I installed the plugs and torqued to manufacturer's specifications. I also installed the plug wires, with a firm click into place. Everything fit normally.On my initial test drive, I went on a 100 mile trip. About half way through, one of the 4 spark plug wires popped out of the engine block (I blame the plug wires, not the Autolites). After returning from the trip, I replace the plug wires with the stock plug wires I had initially changed out. The car ran fine.While using the Autolites for another several hundred miles, I noticed a drop off in gas mileage, and no noticeable power gain. I was down about 4 mpg, which is pretty significant to me. After another tank of gas, and similar gas mileage loss compared to stock, I opted to change back to the OEM recommended plugs. The car returned back to its normal gas mileage.To be fair, the autolites did work. They did not, however, return better gas mileage nor noticeable amounts of power.I do not advise others to change to non-OEM plugs because the manufacturer knows what spark plug works in their car best. If your car uses these plugs as standard, then by all means, use them. For my 1998 Civic, it did not perform as claimed and hence the review.To anyone who has read my review in the past, I did rant on the last review and have since cleared up any confusion. I write reviews to help people understand what they are buying. Just because you are buying something that Amazon says will fit your car doesn't mean it will perform better than what you currently have. Lesson learned.

Great plugs but poorly packed for shipping. Plugs where just thrown in a padded envelope, all but one had came out of there boxes inside the envelope and the ends bent had to reset the gap on 2 out of 4. Luckily there still usable.
