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..

 

[DSMraver]

thanks for the input so far, well i guess i'm going to veer away from Vpower if they are too short and don't meet the proper heat specifications. I'm not buying for 'extra' performance or anything, I just got this DSM, it sputters at high RPM and is propably attributed to old plugs[ previous owner was lacking when it came to even basic maintanence..its either plugs, or dirty injectors, or boost leak..maybe a mix of all 3...but i'm going to by plugs and narrow it down] . I just want some decent plugs that aren't going to fail, and I had heard good stuff about the NGKs on here. I'll go searching for NGK plugs at some other stores around here.

come to think of it, when i mentioned the plugs and he brought out the Vpower to show me he initially asked 'is it for snowmobile' ..so yea....not going with those.

To check if they have the correct plug, compare it with the one that comes out of the car. If it's correct, post the plug # up here.

I'm using NGK V power (heat range 7) in my car WITHOUT any issuse and ALL my friends with 1JZ and 2JZ engines are using them as well.

I have a 1996 turbo eclipse that just got rebuilt everything work great but...My spark plugs are sparking out of hand.there pretty dam loud...
what could be causing this??

I change the coilpack.
I change the plug wires.
I gapped the plugs to .28

 

[norice4me]

ok yesterday i bought a used coil from dsmotorsports and the plugs were fouled out so i got new ones and the same thing is happing again what shopuld i do.

 

[DSM90AWD]

Were your plugs fouling prior to the getting the new coil? Is it the right coil for your car?
There is diff p/n btw 1990 and 1991-1994.

 

[norice4me]

no they are old plugs and they werent fouling befor the new coil and yes the coil is rite for my car i got it from dsmotorsports.com could it be the plugs just being old

If you're running 7s, go back to 6s.

 

[Deathmug]

I just picked up some Bosch supers (7506) & they came gapped at .036.
I was going to gap them at .028. Is it safe to just push down the ground electrode?
Or should I just take them back & get some NGK BPR6EY's?

 

[haut]

when I have to close the gap on a plug I put it in a vice with wood blocks and carefully gap it correctly...


Never heard of a bosch supers, but IMO, all bosch products are garbage

Get a set of NGK's

you might even want to go a step colder if your not running stock boost levels

I second that...NGK BPR7ES and gap it in a vice.

 

[ryanman]

Take them back and get NGK 6's. You more then likely don't need 7's.

 

[IHeartTurbo]

Well most likely, the reason they are gapped at .036" is because they are for a non-turbo application. That's a normal non-turbo gap.

 

[blackGSX2g]

I'm not sure what boost he's running, but he should be runnning a better turbo than stock with a good 3'' exhaust...if your running stock boost, go with the 6s, if you are gonna run higher its a good idea to switch to the 7s.

I don't believe in "pre-gapped" plugs. I check and gap every plug as it comes out of the box. It's amazing how far off they are at times.

^ ^ ^ Bingo. There's no such thing as a "pre-gapped" plug. Anyone who says there is, is not only full of crap, but a lazy mechanic.

Gapping gauges come with a bit for bending the side electrode.

No mechanic will ever admit to closing up a gap by tapping on the electrode. And every last one of them does.

Gapping pliers are worth the $15 bucks. Especially after tuning up the third V-8 that day.

German motors love Bosch plugs. For DSMs, stay with NGKs.

Thank you all for the input! I’m going to order up some NKGs.
Does anyone have any experience with the V-power plugs?
Or are the normal ES’s the way to go?

 

[Defiant]

The ES plugs seem to be just fine. I've not found any backup to any magic plug claims since back in the sixties when they tried to hawk suface-gap aircraft plugs to the car market. Then there were the Splitfires...... gaaaak.
Interestingly, the stock DSM turbo plugs were twin-electrode NGKs. There's no apparent advantage, as the BPR6 or 7ES seem to be the favorites.

 

[IHeartTurbo]

There's no point in split fire plugs anyway. Electricity travels the path of least resistance, so all it's going to do is jump to the electrode that has the least resistance. It's not going to split up between the two, all of it is going to go through the same one. So it's going to be just like a normal spark plug with one electode.

I am actually runing with the BPR6EY (V-Power) plugs.... the car feels excellent. I don't have any claim about those NGK... I believe that they are almost the same that the BRP6ES, except for the electrode in "V". That's all... Price is almost the same also...

About the missfire (splitfire) plugs, IMO I never would use them :thumbdown :thumbdown

Good Luck!

sup everyone, duno what type of plugs to be using on the new motor. i'm currently just usin the stock 6es with stock turbo and fuel setup. gonna change everything after smog to 660cc injectors, 50trim, afc, etc..etc.. i just want to know if it matters whether i use the 6es rihgt now or should i just stick to the NGk 7es?

 

[c5chris]

Stick with the colder ones.

 

[diambo4life]

What he ^^ said. I personally run NGK BR8ES (no typo! ) and I love them.

 

[MrPikolo]

What he ^^ said. I personally run NGK BR8ES (no typo! ) and I love them.

Yeah, I'd run either the bpr7es or the br8es.

 

[1LE]

I run the 7ES and am contemplating stepping back up to the 6ES. 7ES make the car kind of hard to start and is a minor contributing factor in my ongoing "won't idle when cold out" problems.

 

[Defiant]

CRIMINY!

Is it the 28th already?

Wrong forum. Nice searching. And everybody, find something worthwhile to bicker about.
