Hey guys, i have a b18b in my civic, i figured the integra forum would turn out the best for me. I have internaly stock b18b, same old same old bolt ones (i/h/e). But i just think i should get new spark plugs cus it's been a while. Is there any you would suggest? Im in the blue on knowlegde of individual spark plug specs. I can just go to advanced auto zone and they'll tell me what to buy, but here on honda-tech, you guys know your ****. So what do you think, what brand/power should i get?

thnx



what kind of spark plug for a b18b?

 

NGK Copper plugs 1 heat range colder than what autozone recommends.

Works like a charm and is cheap to boot! :D

 

tight, thnx for the suggestion.


just wondering, why do you think colder works better?

 

I really like the ngk's there are two different models, platinum and copper

copper - ngk zfr5f
platinum - ngk pzfr5f

 

so which ones better of those two. copper like xero-cool said? or the platinum which sounds better lol no, but really which is better?

if everyone thinks those NGK Copper plugs 1 heat range spark plugs are good, then i'll go get them

everyone agree?

 

BKR7E-11

use that plug. it works awesome. just make sure that thier gapped to ngk's specs.

 

I just switched over to the oem ngk bkr7e-11 and haven't had a single problem with them....For costing $1.59/plug, they're good.

 

xero-cool why one heat range colder,ive been told this before also but never got a respons as to why...

jdmotorsports..BKR7E-11 is a saab plug,according to ngk.com anyway,why do u suggest that plug...

i use the ZFR5F-11 for my b18b,they work well,one step colder would be zfr6f-11 correct?

for the original poster plats just last longer,but copper creates a better spark..

maybe this will clear it up for the original poster as well..
thanks

 

cause its 1 heat range below the normal plug and its the vgrove which had proven its self to work. when ever you do any serious mods to an engine you should run a colder plug. even mods like i/h/e can increase cumbustion temp. running a colder plug will pull that extra heat from the c.c. and bring some efficiency back.

well if you read the car user manual....it says to use 1 step colder plugs for "agressive conditions" or something like that.....

with some light mods you will be sucking in more air.....which will be getting more fuel which will be burning hotter so buying colder plugs will help dissipate the heat from the combustion chamber to your plugs better and help them run at a optimal temp....

 

get the NGKs. Stay away from Motorcraft on your import.....

 

cool so one heat range colder than the ZFR5F-11 would be ZFR6F-11 correct..and this will also prevent hot summer detonation under load too, i read that here in a thread a while back..

thanks fellas..

 

i used to run the cooler plugs for nitrous. but the stock plugs will do great for just bolt ons. either one you run, will work out good. they both only cost 1.50ish.

differece in the platinums and coppers will be price and how long they last. coppers actually spark a little better since coppers the better conductor, but copper burns up quick. platinum plugs normally dont have to be changed for 100,000 miles. platinum plugs i believe are around 10.00 appiece.

 

thnx everyone. also, do you recommend buying new spark plug wires? arent you supposed to change them out every once in a while?

 

ill say get denzo or ngk spark plugs, they both good about changing ur spark plug wires thats a gud idea but not necessary it depends on ur budget and depends if u wanna change it... but if u wanna chage it get the NGK one too the 10mm i think ..

this is bang on.

I really don't see a need for him to run a 7 heat range on a stock motor. Stick with stock heat range copper plugs.

 

plug wires usualy last about 80k miles. the ngk ones or bosch ones are fine. there is also a place http://www.wire4cars.com they sell custom made wires and are resonably priced.

 

if you haven't heavily modified your motor, i would just stick with stock heat range or if you really want to, go 1 step colder. i wouldn't recommend going 2 step colder as it wouldn't benefit you any, and MAY cause you problems during the winter. 2 step colder plugs are only recommended for forced induction or high compression motors. being that you have an LS motor, 2 step colder is not neccessary.

 

can anyone elaborate a little more on why running one step colder plugs would benefit a b18b just running bolt ons....i always though that for mildly modified engines it would be better to just run stock range plugs ...and that one step colder would result in a loss of power.

 

On the same note....not jacking the thread...just looking for a quick answer from all of the knowledgeable HT guys...what is the NKG part number for the 1 step colder plugs on my 92 GS-R.. B17A1...
Thanx in advance!
