spark plugs

When turbocharging a ka what plugs do you reccomend? Also what heat range?

Its going to go different for what application your running, best idea, talk to whoever is building your engine. If, for example, you are running high EGT temps your going to want a colder plug, and vice versa if your running colder EGT Temps. But first option and idea is to talk to someone who is either building your engine, or someone who has the same setup you have.

im building it my self im getting the nsport kit to start with as a base and upgrade my fuel system and so forth later on. i heard iridium plugs are suppose to be the best thing for turbo apps. im going to do all the tuning myself and building the engine except for serious maching. i'll have a shop do that.

Denso Iridium and then NGK-R Iridiums...I've had just about every type of plug installed in my car. Those have had the best results.

hey WD, whats the diff. b/w the Denso irisiums and NGK's iridium's?

i thought only ND had the ability to produce iridium so any plug labeled "iridium" was ND

[dufiwon]

what do you think about blitz iridium plugs?

1 to 2 heat ranges colder than the factory specs is good. If you are stuck with crappy california gas like I am 2 heat ranges colder.

hey if you dont want to spend alot of money and you want to play with different fuel setups I suggest stay with NGK. If you are going to go with the Nsport Kit Stage 1 go with NGK 6 plugs they are a step colder than the stock 5 plugs. The 5 and 6 are in the stock number I.E. BK6NRE or something like that. If you are building it yourself and are new to the game this will save you money when doing trial and error with fuel setups. They only cost 6 bucks a set and they work great.

hey dufiwon what part of florida I myself am south florida but north of miami

Sorry guys, been so busy lately I forgot I even made a post in this thread.

I was going threw a set of NGKs every 2 weeks, the ND's would last for a little over a month. This probably won't happen in your car. I went through alot of plugs because I was running a very lean A/F mix all the time.

Piggybacking on what Mr Wolf said, Get your car running right before you invest in a real good set of plugs. You don't want to foul a set of ND's cause you were idling super rich.

NGK makes Iridium tipped spark plugs as well as ND.

i live in north fl in jacksonville

NGK PN# BKR5E-11 B=thread pitch, like a M14x 1.25K=socket sizeR=resistor type5=heat range(1-10, 1 being hottest)E=i believe denotes the plug being a "v-power" plug11= 1.1 mm gap, or like .045 for you dermesticsthe NGk stock number happens to be 6953

[dufiwon]

what exactly does the heat range mean? does it mean it the plug stays colder than factory plugs?

[95_240sx]

No, I believe it is that the plug is able to fire when the engine is hotter, at least thats what I thought.

Maybe we'll learn something is someone wants to educate us.

heat range is dependant on a couple factors, the amount of ceramic insulating surrounding the ceenter electrode, and the air gap within the insulator

too cold of a plug and they will foul out, ie run rich and wont burn completely

too hot and you run into detonation and ****
