Hey guys I've been floating around this forum lately and it's helped me ton with my cobalt ss/sc. So I thought I'd just throw this out there to keep others from doing damage to their cobalts.

I installed E3 spark plugs in my car about three weeks ago. And they worked great for bombing around town and my typical short drives here and there, but over Christmas I drove approx 4 hours straight with them at (135km/h) on cruise control which caused one of E3 spark plugs to melt. The piece that melted off then hit the piston and bounced back up and broke off my exhaust valve. So save yourself time and money and stick with the AC delco.

Hope this can save someone else te hastle that it has caused me.

 

i thought it was already known to stick with stock style or ngk plugs.

 

old news man on the e3 plugs and the lsj dosent come with acdelco plugs it has ngk stock

 

Yeah there was a warning on here a while back about those. Products/Companies that false advertise like this need to be shut down. Hope you aren't out of pocket $$ too much.

 

Ngk ftw

 

Why would you skimp on something so cheap like plugs?

 

I don't think its a case of cheaping out, more of people thinking they are gonna gain 10 mpgs with the E3's

 

Shrug. e3 plugs are 5.99 and ngk are 7.09 at my auto store, that's for 1 obviously.

 

i pay $11 for a set of four bkr7e's from napa.. go to a different store hahah

 

I wasnt meaning to offend anyone, just trying to put out some helpful words so take it or leave it.

And where I live E3 are approx 3$ more over the NGK.

Lesson learned for me, just wanted to spread the word. Didn't know someone else has already brought it up.

So far it's crossed me 1004$ to put it all back together. Just waiting to get my head back from the machine shop.

 

holy **** dude, sorry to hear. what a mess coming from just a $3 spark plug

 

Yeah it's kinda a pain in the ass but atleast while this happened I can spruce up the engine. "Head gasket, oil pan gasket, tensioner, timing chain, sprockets, cam and what not.

I had extra money kicking around since I sold my CTS V to buy a house and I scooped up my SS for a fairly good price.

Also being handy with tools has saved me any labor costs dealerships would be charging an arm and a leg for

 

I'd be callin up E3... and maybe a lawyer?

 

I tried phoning e3 and they said they'll just send me new spark plugs. So I obviously don't want those

 

lmao ya think

 

 

sorry to hear man.

all of those multiple electrode plugs are trash and pointless.

 

Don't feel too bad. I did the same on my fourth gen - thinking the E3's would actually be better than the recommended AC Delco's, and I had issues until I swapped back to stock - and then I found that everybody on the LS1LT1 forum already had **** opinions about them.

Sometimes the only time you find stuff like this out is when it smacks you right back in the ass. Unfortunately yours included a valve.

 

Yeah I never looked into this issue until after it happened. But just got word that my head is fixed so I'll start reassembly tommorrow !!

 

Rock auto sells spark plugs for good prices, if i remember i got 2 sets of brk6's for like $15, that included shipping
