Review on 🔥 Fram Autolite XP5325-4PK Iridium XP Spark Plug: Enhanced Engine Performance - Pack of 4 by Jim Ball

I used them on my 2006 Toyota Tacoma as preventative maintenance, not to fix or fix a problem. They replaced the Iridium Bosch. So I wasn't expecting big performance improvements. So they increased gas mileage? Not really. Most cars older than 12 years lose kilometers. Did they improve the idle? No, there were no idle problems. Did they improve the zip code? Maybe small. Denso recommends changing the iridium plugs every 30-40,000 miles. Others say 60-70000. Bosch was just over 50. Do they last that long? Maybe time will tell. As a result, they haven't compromised performance and are currently half the price.
