39 dollars for parts? Hopefully they aren't champion plugs. Hell of a deal
Champion copper plugs are great! Why change if they are working perfectly? Copper is a better conductor than anything other than silver.
It doesn't look eroded. It looks like the centre electrode tip has fallen off. That shouldn't happen. I usually only use Bosch or NGK plugs. I've never heard of Auto lite...
Word to the wise, avoid using anything but the OEM recommended Champion Iridium plugs. Jeeps are pretty finicky when it comes to the sparkies.
When I started the vehicle up, it woke up really aggressive, there was a strong gas smell and it stuttered badly when driving her, along with the check engine light flashing at me when I did the test drive.\n\nAfter taking out the coil pack, I found that there was a lot of crap inside the springs within the boots...looked like dielectric grease gummed up by the previous owner. After cleaning all those springs and making sure they were straight, I took the new Spark plugs out (Champion Copper) I rechecked the gap and they were all good, after putting everything back together the old girl started up quick as hell, no shaking or anything. I drove it for 15 minutes and I had no issues whatsoever.
Changed valve cover/gasket and installed new Bosch plugs and NGK boots.
Car had slightly higher rpms at cold startup but didn\u2019t think anything was wrong. After a few days engine started to misfire. I did some research and it sounded like I should use OEM plugs. I purchased Nissan plugs from the dealer and replaced the Bosch plugs. Misfire went away, but higher rpms at cold start persisted.
the guy said the spark plugs I used are the issues because they are champion brand and I needed to use NGK brand for my Acura
I have a 21 xlt 4wd 2.7 and I do A LOT of driving for work. Recently crossed 80k miles and it started misfiring like crazy shortly after that and threw a code. Pulled the plugs and they were definitely fouled. I did some reading and saw most people change the plugs out around this interval so I went ahead and did it. EVERY auto part store near me only had 1 or 2 oem plugs and I couldn\u2019t really wait so I went ahead and got BOSCH iridium plugs. Well I\u2019m noticing when I get on it or go to speed up at higher RPMs/gears, I\u2019m getting what feels like stuttering or very minor misfires every now but it\u2019s not throwing any codes.
A few years back I bought a box set of eight Champion spark plugs that were made in Russia, and four spark plugs did that.
I've seen it multiple times in Champion in a small engine shop.
