E3 Spark Plugs

[SubSonic]

has anyone tried these in there car yet. i had them in my old Jbody and got 2 mpg better, and was wondering if anyone has tried them on this motor yet

I'll be watching this thread

Just buy an indexing washer kit and index your plugs. Not that I don't believe you but I'm just not convinced shrouding the spark with a bunch of electrodes can possible help. I don't know if they're still out there but there were spark plugs with 4 electrodes a while back, they didn't do much.

There are more then one spark witch ignites the gas more evenly

 

[Stew]

There will be only one spark to whichever electrode is easiest to get to. Electricity follows the path of least resistance.

It has also been debated that the multi pronged plugs act as a barrier agianst the air/fuel and flame front. Haven't seen adequate evidence to determine if they are an improvement or downgrade from single prong plugs. Although my race bike had noticably worse throttle response with a four pronger.

Haven't heard much about the E3s so they're nuetral in my book thus far.

You have a point..... I also knew this..... guess its time for me to go to bed

I know they are suppose to run hotter than most plugs. I really wouldn't like to use them with a turbo. On all my dsms I have run NGKs 1 step colder.

Changing the plus in my z24 restored in a slight bump in economy. I replaced the old ones with the same part number plug as came out. I do not trust the claims made by e3 or those sponsored by them. To much room for bias.

These Plugs really help 1.8L vehicle.... BECAUSE RACECAR!!!

Anymore data on this yet? I have searched the E3 website and they do not even list a part # for the Sonic?

It took me a little bit for a cross reference but i found it to be part number e3 64. E3 has a lot of bad reviews as does pulstar. Im afraid to try them haha

I swear by auto light and nkg.

 

[BRNZY]

I have used the E3's on a few vehicles and have never had a problem. As far as improved MPG or performance, I cannot say for sure.

 

[klb1.8]

So has anyone actually used these on either engine?

 

[GeneralZod]

As was said, indexing works big time. Just by indexing on my LT1 I saw 4HP at the wheel. It was also a massive PITA when you can't see the plug. The LT1 really liked indexed plugs.

I thought about doing it to the 1.4.... Because commuter car!

 

[mitdr774]

Not sure how much gain could be had by indexing on a DOHC engine. If you gained 4hp on a 350, i dont see a whole lot of gain on an 83 or 110ci engine.

 

[sx sonic]

Throttle response or MPG could see a measurable improvement. Personally when it comes to plugs, wire, coils unless the system comes from the factory inadequate (not too common) then no measurable gain will be had as long as all those components are in good working order/not worn out.

Once the engine starts getting leaned on and making more power or revving high some gains can be had. Or from my viewpoint+expierences, loses can be prevented.


Genreralzod- it wouldn't be a bad idea to check your plug gaps. Many members, myself included got plugs improperly gapped (some close, some way off). Some have reported better drivability and/or mpg after regapping. .28" for the 1.4T. .32-.35" 1.8
