Autolite Iridium XP Automotive Replacement Spark Plugs, XP5325 (Pack of 4)

good performance as oem.

very good quality

Working well for my Dodge Ram 2016 v8 5.7

Good price and they work! Fit just fine in my 3.5L Toyota Aurion.

acabados de buena calidad, ajustaron correctamente en mi automovil, mejoro la marcha de vehiculo, pero una de las bujias venia cerrado el electrodo, aprentemente por un golpe.

تقريبًا هذي عاشر مرة اطلب من الشركة نفسها بواجي

Por el momento están funcionando muy bien.

I suppose it is a little difficult for the average garage mechanic to compare spark plugs from brand to brand, but cost is always a factor if you are not installing in a high performance vehicle. Autolite has been around for decades and I can honestly say that I have never been disappointed in the performance of any of their products. They are pre-gapped and thread in easily, despite the almost impossibly tight confines of V-8 engines these days. (Always check the gap anyway) These went into a 2015 Ram 1500, which has more room than most, but the plugs near the firewall are covered up with all the ancillary systems. In addition the Hemi requires 2 spark plugs per cylinder, so twice the effort and frustration. In the end, the truck runs great as usual and no difference in fuel mileage. All this adds up to success without paying a professional mechanic at the dealer some $200/hour. My only complaint had nothing to do with the quality of the parts, but the experience I had in getting them delivered. I ordered 16 plugs. It took about a week to get the first 4. I got 6 a week later and the remainder of the plugs were more than 2 weeks later. By this time, I had purchased some of the plugs from a local auto parts dealer to finish the job, so I returned some of them as unneeded.
