Owner reviews for spark plug

Ignition coil most likely. I have done many dozens of them. Takes about 2 minutes to replace.

Champion copper plugs are great! Why change if they are working perfectly? Copper is a better conductor than anything other than silver.

I’ve just bought some HKS spark plugs for the i30N.

I plan on doing the spark plugs soon just picked up NGK Iridium plugs.

I’m happy with HKSMR45XLZ sparks.

I’ve fouled a set of plugins on my ‘13 800 etec using that oil injection function before storing the second year I had it. I never used that function again, and I haven’t fouled any plugs since.

spark plugs and coils (first ride was smooth I though yeah but then manifested again) main motor mount (better revision, nothing changed, the vibration goes on)

Dont use autolite garbage, this isnt uncommon with cheap plugs. Get NGK Iridums

Pulled the spark plugs and #3 has burnt away the centre electrode. Plugs aren't all that old. Plug brand is Auto lite. Any ideas on what may be the cause?

Be glad it's not the 5.7 Hemi! Those take a special plug, and when jeep released the specs to the manufactures, they got it wrong! So if you put 16 plugs into your Hemi, it will buck and die on the highway.
