Spark Plugs for 4G63T? [Merged 12-28-2021]

[TsiRacer93]

yea so my cars got like 100,000 miles on it, what are some good plugs to be using? i was thinkin bosh 4s but someone told me they would be bad for my car..

Also spray some compressed air in the holes before you remove the plugs to make sure nothing falls into the engine. RRE says to gap to .030 for up to 16 psi and .028 for 17 psi and up. Chiltons says you should check the gap every couple thousand miles cause the gap will slowly widen.

anyone know the cheapest places to get NGK plugs and Accel wires??

i asked at a local autozone and pepboys, but they don't carry them.

thanks

Iridium plugs at Schuck's go for $15.00 a piece where the ngk website is soooo damn inexpensive, it's sick! As far as wires go, I would not recommend Accel wires cause I used them before and meh they didn't do as well as the current MSD wires that I've got! If you have your heart set on Accels, then you can go to Schuck's also cause they should carry it or at least should be able to special order it in a day or so. I work at Schuck's so I've had the pleasure to test all the ignition wires & good stuff on my car. Yeah ngk.com should take care of your plugs for you! Make sure you use dielectric grease & anti-seize grease before you start installing it into your car.

DSMs have no use for iridium plugs.

this may be a dumb question but i am getting to platinum spark plugs and ngk wires for my 97 n/a . is there anything else i need to get in order to keep anything from going wrong (i.e. performance chip, injectors, etc)

 

[talon84]

hey guys its time to put a little more spark in my life..... looking for help picking out new spark plugs any guidence would be most kind........

 

[boriqueno96]

just get some regular ngk's.
there's no point in you spending a lot of money on your ignition system with what you have now.

 

[lilalex86]

NGK plugs, air filter, fuel filter, pcv, oil and filter,check rad hoses, check vac hoses, check trans fluid,check batt, etc. Stare at open hood long enough something will break then fix that.

 

[marcmsj]

just do your general maintenance checks periodically... then start modding and watch things break.

 

[Ja17Bmx]

Well if your going to be putting some mods on anytime soon, i would go with some ngk iridiums, but if not there is no point in putting any performance plugs in because there really wont do too much without any supporting mods like plug wires or a coilpack.

About the only thing the user gains from Iridium plugs is the "plug change interval", and a little hotter spark.
New cars today can go 100,000 miles before their first tune up, why, because most of them are a serious pain in the ass to work on.
I bought some Denso Iridiums for my GST, and didn't like them at all.
The car would idle rough, pop while idling and it just seemed laggy.
I bought some standard NGK BPR6ES, gapped to .028", and the car idled smoothly, and I had instant throttle response.

Save your money, buy the factory spec NGK's and get some good quality wires.
The plugs need to get the energy from some where right, you need to get a good set of plug wires with minimal resistance per foot of wire.
Check out MSD, they have some pretty good ignition upgrades for all vehicles.

I've seen threads about plugs wires and resistance... <a href = http://www.dsmtuners.com/forums/showthread.php?t=147476&highlight=ohms+per+foot>Click Here</a>

 

[marcmsj]

go for the ngk's BPR 7ES

they work great and go for under 3 bucks each.

 

[TheCzern]

Platinum plugs are a waste of money Imo.

just get plain copper NGK's. ive been running copper NGK's while running nitrous, and now that im turbo. plugs will not do much for you.

 

[Defiant]

I'm sure there aren't any spark plug threads for N/Ts anywhere on this site.

Platinum plugs are a waste of money Imo.

Seconded. A waste on N/T engines, and dangerous for turbo engines.

i am close to getting this thing back together and am wondering at what point do i need to bump from 6's to the 7's. basically have s16g plus supporting mods. would like 18 psi on pump. list will give info.

thanks,

jim

 

[TheCzern]

what do you guys think would be best for the car?

 

[Defiant]

BKR6ES-11 gapped at .050

 

[Defiant]

I'd stay with 6s until you start making them fail. Cars are driven a whole lot more in traffic than they are in races. If you go to the track, you might swap in 7s.

how would you know if they're failing?

misfires?

 

[99gst_racer]

Usually, most DSMers switch to the 7's once they turn up the boost w/ supporting mods, or once they do a turbo swap.

FORMONTOYA - In your case; a 16G @ 18 PSI on pump, I would def. recommend switching to the 7's.
