Spark Plug ... hot or cold - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Hey question ... just bought some Bosch Platinum +2's.

I have a 90 240 ... is this plug to hot or cold for this car?

Does the KA engine run better on a hot or cold plug?

Just a few dumb questions .. I know nothing about this
engine. Just trying to find the simple stuff out.

Thanks

Well, they could be fine...but since you didn't specify if you are talking about the stonk heat range, then who knows. Click the link and it'll tell you a little about the heat range and stuff...not much help...oh well

Hmm.... Ok. But I understand all that, but which plug runs
better in the KA engine???

Bosch or NGK
Platinum or Standard Crap-o ceramic garbage
(Forget Iridium plugz, WAY to much money!)

Thanks again guys.

p.s. I KNOW everyone loves the NGK V PLUGS ...
but I have the bosch plat's +2's and love them,
just trying to see whatever suggests.

Was your reply directed to my post? If you so, then you don't know. I can't tell you if a plug is too hot or cold based on who makes it. There is a temp range indication in the part number. If you want to know what temp range it is, you need to refence that.

Everyone seems to love NGK's. They're realatively cheap and seem to produce good results (platinum versus standard is really just a difference in life span, platinum costs more, and gets changed less, I don't think there's a big performance difference). I had some cold bosch platinum plugs from the previous owner (temp range 7 which is two colder than stock) which were fairly gummed up when I removed them. I replaced them with some NGK V-powers (heat range 5 which is stock) and really didn't notice any difference. I have yet to remove them to check how they are wearing though.

By the way, I'm not sure where you get your misinformation but all plugs I know of incorporate "crap-o" ceramic. The platinum is only the electrode, it is still set in ceramic. Standard, platinum, iridium...all have ceramic in their construction. Read the link dammit!!!^^^

Edit- I think I may have originally had my temp range for the plugs backwards. I switched it to read 5stock, 7=2colder which I now think is correct. I apologize since I changed these last spring and haven't thought about plugs since. I THINK these are the correct values, though I don't have a manual with me at work. If 5 isn't stock someone please post what is. I know 5 and 7 are the values, I just can't remember which was which.

ngks are the way to go, the platinums are pretty hot burning plugs. the ngks have diff heat ranges. Basically if your runinig nos or turbo you should be runing colder plugs. I use the coldest ones ngk offers. For na it really shoudnt matter that much, i think the platinums are a good choise, just for lifetime longevity.

Does it even matter which plugs i put in my stock ka24e?

Would it cause me to burn rich in any way?

Next time around I will stick with the NGK V-power plugs
I guess. Any specifics? Or just stick with the Vpower (stock
i think right in the KA?)

Eh, whatever. I give up on cars!
