ezwong, does your car feel sluggish during cold starts with standard ngk7? Since they are colder plugs. I'm still using NGK6.

Alot of misconcepts about "Cold plugs".

The plugs itself does not radiate heat. Colder plugs are able to stand up higher combustion temperature rather than turning into a C.I engine glow plug and colder plugs have better heat dispersing capability.

It will not have any affect on cold starts.

how about more likelyhood of fuel contamination on standard cold plugs(not iridium tip)? Is that a misconception as well?

 

[Joeker]

Then you have to look into the air fuel ratio.

Unless you are burning way too rich to begin with, its unlikely your plugs will be coated with thick layers of carbon from uncombusted fuel.

But make sure if the plugs are fouled by carbon or sooty thick black goo. The former indicates rich while the latter could be a tell tale sign that you're burning too much engine lube.

i'm not using No.7 plugs in my car, my fren with GSR engine is.. and yes.. it's sluggish with cold-starts.. have to wait around 5-10mins to get it warmed-up. after that.. it's like normal, but according to my fren.. if he use No.6 plugs.. when he does high-rev the car jerks. after using No.7 plugs the problem of jerking went away.

EVO3, yeah RM35 for 4pcs

hehehe..change to NGK 6... the jerking not dere ne more ( i hope), try a few time but it OK lo... can't get NGK 7 in my area, mayb poor demand...heheh..cost me RM48 for 4 pcs.

The jerkin gone but the car tend to misfire in the morning...mayb i haven't adjust the plug gap yet..hehehe....

joeker - if the engine is burinig more fuel then the spark plug will be black right...how a bout a little white color with brown spot?

 

[Joeker]

white color with brown spot? sounds like pap smear infection :lol:

Difficult to say without seeing the plugs.

THis is how I read my plugs. If it looks like KFC friend chicken skin, golden brown, the A/F ratio is ok.

If its glazed powdery white, its lean.
