Halo Spark Plugs

[Island Solara]

Hey guys! I don't know too much about cars & need your help. I wanted to change (upgrade maybe?) my spark plugs soon, but got mixed results from askin' around. Most people said to use NGK spark plugs, a couple people said to use Halo Spark plugs. See link below.

I haven't heard of Halo Plugs before, but I did check their site out. Not sure if it's better or worse than NGK plugs.

Any input, opinions, exprience welcome. Thanks!

NGK because it's a name I know.

im on NGK, its the brand that came out of my car stock. Just replaced with the ones recomended for boosted cars

NGK plugs are very good quality. Platinum plugs are DURABLE, but NOT the best conductor... I stay AWAY from them. (The drawback is you can't go as long without a change...) The BEST plugs I have ever used are Beru Silverstone Plugs... 99.?% pure silver core/electrode. I believe they are about the LOWEST resistance plug out there. (Standard equipment on Porsche 911 Turbos... I have heard... the 3SF size, I think...) It just so happens that is the same size for my Turbo Supra, and since I am running NOLOGY HOTWIRES with them, my performance/mileage improvements were DRAMATIC. I would study the topic further, however, in that NO resistance means NO delay in transferring the spark to the cylinder gases, and since CONVENTIONAL RESISTOR plugs have SOME delay, the Silverstones may have an adverse effect on this "subtle" phenomenon. The reason they work so well for me is the COMBINATION of the NOLOGY WIRES which have capacitor windings that serve as the "charge/capacitor" that delays this spark, and then delivers a much more intense, short duration spark to the combustion chamber... initiating a better frontal end burn.

HALO? Not familiar... but if I haven't heard of it, I would DEFINITELY stay clear... (The web link/page looks GENERIC to me... not a good sign. Perhaps another "SPLITFIRE" gimmick?)

NGK, NGK "R", NGK IRIDIUM.... all very good selections.


(Next, consider spark-plug "indexing" for optimized combustion....)


Lastly, REMEMBER boys and girls... it is NOT an EXPLOSION in the piston/cylinder chamber... it is a CONTROLLED BURN that you want... a GOOD FRONTAL END IGNITION at JUST THE RIGHT TIME and you DON'T NEED multi or rapid fire ignitors... just ONE GOOD WELL PLACED SPARK at JUST THE RIGHT INSTANCE... from there, the properly controlled burn should PUSH the cylinder through it's stroke with a STEADY, COMPLETE burn path through the mixture....



....er.... at least... I COULD be right......

Thanks for the input guys! Especially Crisp, nice write up. So, for the Solara, what would you recommend? NGK? If so, which one?

[Nyyankees3511]

Stick with densos or ngks. I personally have denso iridium sk20sr11 and those are oem on ES300s and most of all lexus models. Either way you will not gain any hp with plugs you will just bring back lost hp.

[woa_its_j3ff]

i have denso iridiums i find them pretty good

[crispone]

Bump to Denso's as well. They are good plugs. (NY is correct, overall.)

So, it's NGK vs. Denso in a sense. Any one of these better? or is it either or? Sorry for all the questions, but I'm learning.....a lot! Thanks for all the info though everyone.

[crispone]

You will be fine with either.

Sounds good to me. BTW, love the avatar Crisp!

[crispone]

Thank you. iinokturnolii set me up with it. He did a nice job.

Both are great, denso is what lexus uses now. But it doesnt matter.

According to the sticker under the hood of MY solara, it clearly says use platinum multi-ground plugs.

I installed denso PK20TR11 that look like this...


On that same sticker there is a big "NO" cross through the single ground that looks like this...


I noticed a hell of a lot of people on this board are fans of the IRIDIUM PLUGS (i.e. denso IK20) that are "TRADITIONAL" SINGLE GROUND, installed in defiance of the almighty sticker! Why would Toyota affix a warning advising against these plugs?

Here is some info from www.sparkplugs.com:

Thus by having more ground electrodes you extend plug life. It is important to note that multi-ground does not mean multi-spark, there will still only be one spark at a time. Therefore a multi-ground plug will not perform any better and may actually perform worse than a traditional plug, unless the engine is designed for a multiple ground plug.

Am I missing out on potentially more power by using these OEM multi-ground platinum plugs? Is the only reason Toyota recommends them because of the time interval between platinum plug changes? Does anyone else's Solara have this spark plug sticker on the hood? How do platinum multi grounds compare to iridium single grounds in terms of performance and longevity?

A while ago, Jim@foreign affairs mentioned the NGK BKR6EQUP (3199). He had some problems with the Densos. Personally, I've had my Densos for 3 years now without a problem.
Anyway, Jim recommended the NGKs. I found out that those are the same plugs that are used in the BMW M5. That is one bad car. If the M5 uses it, I'm going to use it.
I recently ordered a set from sparkplugs.com. I haven't installed them yet though. I am waiting to but a few more things to make it a whole day project (Mangecor wires, supercharger oil change kit, etc...)
