Ok so today i went to Napa to get new spark plugs, i ordered the NGK BKR7E cause i have read in here that they are the best,

But the guy up front said that those where only some kind of resistors, and that they wont fit my SS/SC..

So i came home and looked at Advanced Auto Parts and they do have them but the will only fit 98 Aston Martins, 04 Volvos , 98 Grnd cherokees but it said nothin bout Cobalt, not one thing.

So i really would like to know if the NGk BKR7E fit the cobalt 2.0 or i have to get other ones,

I saw some NGKs laser platinum but i want either copper or iridum for my balt.

Help please!!

 

i along with a shitload of members have them in their car. it's not that they only fit in those cars, they probably come stock in those cars. i've noticed that lots of guys that work at the parts counter don't really know what they're doing, like in most jobs.

 

exactly. Most people in the world are idiots, you have to remember that. They go to there crappy minimum wage 9 to 5 job, or a few hours a day because they can't succeed in the real world. In return you get half a$$ed information that will make you think twice about the truth.

I have the ngk bkr7e's in my car and so do probably half the people on this forum. They are great plugs and extremely cheap.

 

factory replacement are iridium, so that's what they're little computer spits out, you've got the right part number so just tell them you need four of them. If you need more reassurance just compare the length of the threads of the old and new plugs, they should be identical

ive never been able to get the BKR7Es to work without knock

 

i have some BKR7EIX....will these work fine...whats the difference?

 

I have the OEM factory plugs. Those also work fine...


Are you modded? I'm 3"/42# and the stock plugs seeem ok to me.

 

thanks guys I really felt kinda stupid when he started talking like a professional,

but then he was going to give me a transmision filter and automatic transition fliud, and thats when i figured out that he needed help..

 

people that work at auto parts stores are not "professionals" they are making 8-9 bucks an hour to read a computer screen, theres not alot of knowledge needed, you will learn more on here than you ever would working there.

 

yes im modded 2.2 turbo w/60lb injectors 3"turbo back fully built head from bates forged internals....and i bought these because i thought they were a step or 2 colder....than the oem's is this right?

 

I m bout to get stage 3 in it..

so the NGK 's are copper so that are better conductors they dont last longer than the iridium ones but they good..

 

Is it good to use these plugs only when your car is modded, or is it just as benificial using them when your car is stock?

 

also autolites 3922 are a 2 step colder plug for our 2.0 cars

 

No the 3922's are step 1...

But you are on the right track with the autolite! ITs what i use..

If thats all you have.. one step colder should be fine..

Id stay 2 steps when you hit 300.. or closer to...

 

bkr7e have been discontinued and will be replaced with part number 4646 i beleive.

and rodimus prime what plugs do you use? i am always up for trying different things.

 

I use BKR6Es same heat range as stock, just a copper plug instead of platinum

I have them gapped at .040 and it runs fine

 

1. Plug type has nothing to do with the thread's pitch and length which actually determine whether a plug will fit in the engine or not.

2. Pretty much all gasoline engines in modern cars use resistor plugs.

3. Those are the correct plugs and will fit.



It can be bad for the car to run a plug that is too cold, maybe worse than running a plug that is too hot. On a stock SS/SC there is no reason to go with a colder plug. The typical rule of thumb I believe is around every 50 - 75 hp or so increase you go one step colder.

 

My plugs are still stock with 72,000 miles on them, and they don't miss a beet...

 

What are you doing feeding your cobalt vegetables?

 

It runs better on cabage, then tomatos... No I feed it only 93 octane. I ment to say beat... but still 72,000 miles on stock plugs???

 

I run the BKR8EIX... Iridium, 2 step colder, with my 2.7"... Work just fine...

 

I know I was just kiddin around. From what I've heard most new cars wont even need new plugs til after 100km.

 

i beleive the bkr7es are copper.

 

whats the difference between the bkr7eix from your 8's
