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.
Word to the wise, avoid using anything but the OEM recommended Champion Iridium plugs. Jeeps are pretty finicky when it comes to the sparkies.
2005 Camry 2.4L just changed original plugs at 130k miles. I go 5k on synthetic oil and don't have to add any between oil changes.
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.
Champion are ok if you change them every 2000 miles, otherwise they tend to loosen up at the terminal and you end up having to retighten them on a rigid mount Harley every 500 miles or so.
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
A regional tire store / repair center "recommend" spark plugs on my Sienna at 92K for $850 (intake manifold has to come off to get at 3 of the plugs). I asked them what benefit would there be in replacing spark plugs at 92K considering Toyota sets the spark plug replacement at 120K.
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.
