their sposed to generate a larger spark that any other plug. my friend says they'll weld your piston lol

 

Just about everyone who buys these ends up having something go wrong...

our engines dont like em..

i woudlnt buy them.

 

about 50 bucks for 2 spark plugs, they can be found on amazon.com also, if anyone reads import tuner magazine... they did a test with them. they actually make horsepower. tested them on a lexus 250

 

junque. GM spent more money researching and working with NGK to produce the Irridium plug for this car that for most people spend on their house purchase. For most of us, the original heat range works best. STAY WITH OEM. This is the best advice anyone can give you. Stage your car -2- 3 whatever? One heat range colder NGK . Period.

 

My stock plugs were platinum

NGK PFR6T-10G Laser Platinum

yeah i had to make dinner etc

 

where can i get the step colder plugs for the ss s/c?

 

There is a link in my signature. It talks about using plugs other than NGK. You should read it. Dont use anything other than NGK.



BKR7E (one range colder) or BKR6E (stock range) will work for 90% of the people out there dude.

 

I dont mind my autolites..

just dont get these spark plugs...

end of story..

 

sorry to be "that guy," but I have had these in my car since I got it 50k+ miles and i'd write a good review about them.

 

if these are anything like ZEX you DO NOT want them

 

Qfmft!

 

dont go buying these plugs...theres no point a spark plug is a spark plug..sure one might say it will last longer or provide a greater spark for more effiecncy power and gas mileage..but if so then why didnt they come in the car in the first place? Anyways id stay with factory plugs they are designed for the car and if gapped right then u should have no problem...U WILL NOT SEE A HORSEPOWER GAIN BY GETTING THESE PLUGS. a spark is a spark.
