Owner reviews for spark plug

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...

I only use NGK or Nippon Denso plugs, for a reason after a career as a technician.

Denso iridium spark plugs

Word to the wise, avoid using anything but the OEM recommended Champion Iridium plugs. Jeeps are pretty finicky when it comes to the sparkies.

New Denso Platinum spark plugs. Car drives great, no codes, no sputtering or stalling or hesitation.

NGK are my goto plugs but I’m pretty sure you’ve got the plugs that are notorious for breaking apart when removing them

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.

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.

I’ve had several Denso plugs do this on a couple Camrys I service, and our own. All 2.4 cars. Caused tow ins for both husband and wife’s cars. I’ve fired denso as a spark plug provider, too many failures.
