I just got my new Nology Hotwires for my xA from mmrusa.com

The install took about an hour to complete.
It's an amazing difference in power
I haven't had it on a dyno yet (doubt that I will) but best guess is 5 to 10 hp gain.

I also added a set of Beru spark plugs, also from Nology.

Has anyone else gotten these wires yet?

Scion Bob

maybe 5-10 hp in ego?

Sorry to say, but just upgrading wires won't produce such a result.

i want pics...

i'd definately like pics , i'm wonderin how they even have hot wires on a car without spark plug wires.

Hotbox05 : The 1NZFE does have sparkplugs.

Heck you were the last one to post on that topic.
Of course if I were posting at 430am I wouldn't remeber either

I think what Hotbox was trying to say was that the xB does not have spark plug WIRES. The ignition system is a coil-on-plug setup. When most people refer to plug wires they are talking about the wires that run from the coil to the plug. In the case of the 1NZFE each plug has an individual coil (and igniter) that sits directly on the plug. So perhaps he was just curious as to how the ignition was retrofitted to run the plug wires. I am as well.

Since we are on the subject of beefing up the ignition, one thing that has caught my attention is the AEM Capacitive Discharge system. It was designed for distributor-less ignitions with coil on plug setups. The only problem is that we would need to find coils that do not have the ignites integrated. A guy on the AEM Power site recommended 300M coils and said that he could build me a aluminum plate for our valve covers so they would fit. Any thoughts?

dead on minsk99., yes i know about that , that is just a spark plug change , i'm talking about the nology setup. diga der..... lol

its been done on a ford that also has coil-on-paks

but i still want to see it on the scion....

So, was that 5-10 hp at a particular RPM, or throughout the band? Always amazed by butt-dyno results...

thats a completely different setup , the scions have the coils on top of the plug versus the ford , the ford has distributerless ignition , the scion has direct ignition system. i believe these are the correct terms.

yeah, i thought there was a diff. (was not really sure)

i'll be the first to call BS...
this one post wonder has to prove me wrong...

I'm working on getting some pics taken, I don't have a digital or I'd have them already.

I don't have a lot of the specs, I'm not a mechanic.
I know that they do work. Maybe my "butt dyno" needs to be recalibrated, but the power difference is there. Acceleration is better and the torque increased too.
I've only had them on for a day now, but I'm sold.

My last car (Expedition) had the Nology wires on as well, which is why I went back for more. On my expedition the reason I got the wires was for the fuel savings (10% gain, don't need a dyno for that one).

The extra power in my Scion is a add-on for my underpowered car.

Just got off the phone with a sales guy over at mmrusa.com and here is what he said. The coils are relocated (not sure where) so that the wires can run between the coils and the plug. He claims that the nology wires have a capacitive element to them so that the spark discharge is increased.

hmmmm. how much will that run the usual nology price between 199-299? maybe cheaper? (probably not but one can hope)

I saw it on the website (mmrusa.com) . They did relocate the coils and mount them outside the engine. Have to remove the engine cover to use this setup.

I don't know what is inside the Nology wires. Seems to be like they use normal plug wires and wrap them with conductors tied to the engine frame. This make a capacitive effect alright. I might try doing it myself and see what happens :tap:

:rofl: Why in the world would you add wires to a car that has none? The ignition setup on modern cars are monitered to assure ZERO misfire and the MIL will light if any misfire is recorded (P0300, P0301, P0302, P0303, P0304) This is snake oil at its finest and if there was 5-10 hp available so easily, these guys would be working for a Major Automaker or would liscense their products to an Automaker and we would all have them. If you got a 10% increase in mileage on your Expedition with a mere wire change, you must have had an extremely whipped set of wires on it and It would most probably have had a check engine light on. Sorry to be so skeptical, but I have been wrenching for a long time and accidently picked up a little knowledge along the way. :lalala:

Just add the NGK iriduim sparkplugs and you'll be fine. No need for the wires. Just upgraded plugs. :D

Ah, the Iridium plug debate of 2004. It seems as though it were just yesterday. Kidding, kidding. Anyways, I've been considering these plugs for a while if for no other reason then I am addicted to farting around under the hood :silly: . Anyways, my question is this. Is there a need for a plug that is hotter or colder then stock just from the typical mods such as header, intake and exhaust or would FI or internals have to come into play? Any advantage to these Iridium besides a long life? I'm assuming that Toyota put plugs in there that burn all the fuel efficiently even at high RPM?

id have to agree with scott17 this sounds like the biggest bunch of barnicals i have come across in a long time (exept for the fuel rail magnet remember that one :rofl: )
i have been working on toyotas for 17 years and cannot think of any benefit of this
setup if someone has proof i would like to be proven wrong but i still think its all a bunch o crap to me :rofl: :rofl: :rofl: :rofl: :rofl:

i think that nology is dumb , at least for this car. i will put some denso iridiums and see what happens. can't get any worse.

for normal mods this is way overkill, but for FI this is usefull.

Why? At what compression pressure would the stock system give up the ghost? There are 4 coils, so coil saturation at high RPMs would never be a factor, and the voltage is high enough to light at way crazy pressures, so where would the benifits be? Sometimes a little knowledge, misapplied can be costly to the pocketbook and performance. Stylis always has to toss in the irridium plug "solution" and this is also silly but it won't hurt anything and they should be good for 100k miles. Just don't get your hopes up for any power increases unless you have a vivid imagination. :no: Why do they sell this junk? Because SOMEBODY will surely buy it! :rofl: And yeah that fuel rail and gas line magnets surely take the cake! :rofl: Extremely ingenious solutions to non-existant problems.

Yes sir!! everyone that has installed them over here in the norcal has had nothing but good things to say about them. :D

Nothing wrong with using the premium gas once in a while, now is it. :) I never push anything unless I have it on my car or have tried it out for myself.

Just changes the plugs every 30k and making sure they are gapped properly is just as good.

Iriduims rule! :D A little more expensive, but worth it. I drive my box pretty hard so I would have to change mine a little before every 30,000 miles.

Why? :doh:

Why? :doh:

Why not? :P

i like my engine bay to be clean looking with out all the extra spark plug wires imo

Why? :doh:

Why not? :PBecause.

Its a 1.5 liter w/ high compression that is meant to be used for gas economy and commuting. Are some of these mods necessary for performance? Plus, the ECU has yet to be cracked. For those who want to runthis, props to you, but my 41k miles xB has been doing just fine w/o it.

Why? :doh:

Why not? :PBecause.

Well, that answers everything! :P

Just doing a simple spark plug change restored the responsiveness I felt I was losing. Not gonna claim hp gains or anything but I can feel a difference when pushing the gas and it's idling smoother again. The gap on some of the plugs was up to .36 or so.

Another question maybe someone can answer without having to start a new thread.

I noticed the Denso and NGK plugs run a .032 gap while the Champions and Autolites for the same application run a .044 gap. Why the difference?

This is exactly the problem with many aftermarket parts! The Densos and NGKs are the only plugs recommended by Toyota and this is precisely why. Other plugs fit many other applications and if the thread size, reach, and heat range are the same (or close), they will list that plug for that application weather it is correct or not. That's why I only recommend the stock plug nowadays for ANY car! (Along with wires, oil filters,.....)

What other factors are involved besides these? thread size, reach, and heat range

Style, gap, and quality.

gap is changeable , style as in what how many prongs? quality is for ya know the consumer to decide if they want crap quality they get crap quality.

Well the beauty of this is that Toyota got some pretty smart fellers together when they were designing this engine and hammered out all these factors and options and picked the best plug for this engine and then installed them in your new car for no extra charge!SWEET!

And then you have the so called "experts" who will say differently.

just a lil fact stock obviously isn't always the best. . all i'm saying is that if the spark plug has the same reach , the correct gap , and the correct heat range it will work.

But will it work better? Cheaper?

cheaper probably , better that depends on whether you believe in spark plugs creating performance , truthfully you won't gain very much but a slight bit. i'm just stating that other plugs can be used. if u buy the reccomended plugs theres just less work , but did u know that those recommended plugs are probably factory reccomended for many other cars? the nippon denso's for my supra were stated to fit like 3 or 4 other cars , outta the box. i will say iridium plugs gap should not be changed.

Like I've asked many times before,Exactly which plug do you think is "better" than the stock plug in an Xb?

Hmm, I'd like to know also. Ya know, for future reference.

Iridiums ,i've always liked denso's. ngk's are goot too. i've gone through 3 sets of denso iridiums between different cars and i could feel thru the ol butt -o-meter a tiny gain. theyre not too much , and online is cheaper than in store , in a store they normally run like 12.99 and they can be found about as cheap as 7.00 per plug online.

hey brad what are you running right now?

oh and whatever you guys do, do not run the bosch platinum 2's 3's or 4's they are overpriced and the insulator(the white ceramic part) comes loose letting the spark foul and your motor will bog , it has happened to me twice in different cars and has happened to a friend twice and another friend once. bosch is great but apparently their plugs are not.

NGK #BKR5EYAs. I'm not using a different ignition system, different timing, cams, and such, so I don't see a need unless of course I change fuel mixtures, which I won't.

I've tried them all in the past, and only saw differences when I changed them on motorcycles.

I changed to different plugs when I had my Celicas, but that was because one had an 18RG that was slightly massaged, and the other Celicas had modified 20R with different cams, dual sidedrafts, inner valve springs and a whole lot more.

So if my xB wasn't stock, then I would prolly have different plugs.

Ditto on Bosch platinums, junk.

NGK iridiums, great design. I did a tune up on my buddies toyota corolla and found bosch 4 tips in there. Found the rough idle problem! :D Moved to NGK and had the most perfect idle! :)

Is it just me or is THIS SCOTT17 one of the worst people on Scion Life. Either provide info backing your claims or shut up. People buy parts like these because they want them. This site is used to give help not run your idiot mouth!!!!!!!

It's just you. Really. All I ask is for YOU to provide info to back your claims or shut up. And providing people with ACCURATE info is helpful for those with good sense. Toyotas engineers and the fact that the car comes with a certain plug backs my claim rather nicely, don't you think? If you're looking for support from me because you believe hype and bought into it, you will certainly be dissapointed. Any _______ can call someone an idiot, but do you know enough to educate me so I won't have to be an idiot? I am really eager to learn. :lalala:
