Spark Plug choice

I have searched for diff posts and sites concerning new spark plugs for my 97 GSX' (Lightly modified). New stock turbo, boost at 15psi, down pipe w/ 3" back, type S bov, etc...

I plan to buy new spark plugs 2nite, and im not sure on which ones to buy. Its between these 2 :

NGK BPR6ES & NGK BPR7ES

I know the (7es) is one range colder, but I heard I might experience more back fire from it. as of now I don't plan on adding too much hp (need more gas money...GRR) so what would u do?

Also, what is the difference between BPR and BP?

BPR7ES, make sure you check the gap. this is probably the most recco'd plug out there, just make sure you change them every 10k or so. never heard of backfire problems from these.

why not just get denso sparkplug? are they any good? i hope so cuz i got four for mine and they costed me $50 for 4.

I'm sorry but spending $50 for spark plugs is just CRAZY!

NGK all the way. I spent about $15 total on mine.

i got the bosch platnum 4-pronged,had them for a couple mounths,and i got there wires too,no problems with mine,and why does everyone have ngk,cuz if there better i go get some,lol

Cause platinums SUCK!!!
Bosch sucks IMO

ok,cool why do they suck

Here this is from my chemisty book (never thought I would be using chemisty :p)
Best to worst..
Silver, Copper, Gold, Zinc, Platinum, Iron, Tin, etc.

My platinums misfired after 2k miles. From then it has been NGK!!

oh shit,lol i never knew they sucked,ok good cuz ngk are cheeper too so ill save money,,ps ashah000 with my taillight when you told me to use silicone to stop water from getting in,well i did it and that worked so thanks,ok cool

Use BPR5ES (this is for a NT car)

Call Napa, say you need part number 6953 for NGK. Those are the BKR5E-11 (one range hotter for N/Ts).

cool,thanks i will switch them then

[/waste of money]

hmmm... really? i am running them [iridiums] right now [t-25... don't laugh :P...] and i have had no problems as of yet. pushing 2k miles...

on another thought anyone heard any experiences about Nology Silverstone plugs?

Iridiums probally won't cause any problems and will last.. but come on how much did they cost 15 a plug?

i got mine for like 30 bucks total. but i get deals from my mech too. i had some missfire issues and so i hit him up for plugs and these were what he is putting in EVO8's [he said he got over 15 rides on them at the time, no more bpr7es's].

here is the link to the Silverstone's

Do you have the silverstones in there right now?

They seem awesome.. and these are the first plugs I have seen with silver. But I want to know more.

i'll stick with my copper BPR6ES NGK, their cheap and reliable. plus they get used in cars with a shitload more power than mine with no problems, why waste money when their is no need. save it for the strip club. :thumbsup:

i don't have them in now, i have iridium's.

ya, give the $$ to the strippers so they can get more expensive spark plugs for their cars! srippers need turbo's too!





god i love strippers...

god i love strippers...

yes me too...nothing like a night out to the strip club to make your week better. :evillol:

Last time I went to a strip club was after working on the car all day. It was snowing then. On the ride home we had to stop for some gratuitous AWD donuts on the stutterbox. Dont drink and drive... :p

But you use the colder ones for a turbo setup right?

yes, the 6-7 heat range
