Too fancy for a plug. Just stick to NGK's

**4thGenTA** · 01-17-2010, 06:41 PM

**Mr. Luos** · 01-17-2010, 08:06 PM

I could have told you this long before you installed them...

Try a set of the plain old autolite 103s, been running them for the last 50,000 miles in the goat with no problems at all, I change them about every 20,000-25,000 miles and they still look new

Another vote for Autolites. Great plug, I run them in everything anymore. They do as advertised.
Don't care for NGK's.

Watch the sponsor list on horsepower tv and you will learn why E3 plugs look like a great product on the show.

yea i no that now lol

**Z28_Driver** · 01-18-2010, 05:31 PM

No offense meant. Just hate to see people taken by BS advertising claims.

**Wesman** · 01-18-2010, 05:43 PM

When I saw the title of this thread I figured this would be the result. E3 is just another marketing gimmick.

On the topic of plug designs though, has anyone seen/tried those new Pulstar plugs?? They are very expensive, but they claim big things of course.

I actually am switching from the NGK's to the AutoLite's.
In both cars.

AP606 for the Grand Ma GT (changed today---25 minute chore), and AR103's for the slow car (changing soon---45 minutes).

**Hi-Po** · 01-18-2010, 10:46 PM

Have had zero problems with my autolites, NGKs are a fine choice as well. Those E3 logs are right up there with Weapon X's. Which is a very bad thing.

For most of us who drive the cars on the street. Any sparkplug that is changed often enough will do the job just fine. If you have the extra money to spend on premium plugs, go for it. If you have good results or bad let us all know.
As for the marketing gimmick:
We all have some kind of personal preference for certain brands. Marketing people know this. They see this as a sign that marketing works. If it didn't work we would all by the lowest priced product. Consumers are willing to pay more for a difference in the product, whether that difference is real or just BS.
I personally would avoid any product recommended by a host on a show that is sponsored by that product. They have an interest in that products success. Just my .02.

I rarely ever pay attention to market hype. I don't mind going out and trying new products. I like to experiment whether people say it's good or bad. I've found mixed results.
As far as plugs I had the luxury of experimenting on a dyno one day. We found the NGK's never really made any difference in exhaust gas temps when changing heat ranges.
Not that it's a bad plug, I'm sure they work. We just weren't impressed with colder heat ranges having no affect on cylinder temps. Generally one heat range changes temps about 30 degrees. Didn't see that with NGK's.

On the other hand, the Autolites performed perfectly in this mannor. For that reason alone I switched to Autolites.

I've also been a fan of ACdelco plugs. But unfortunately they don't offer colder heat ranges for the LS1 with these long .708 reach plugs they use. So that cans ACdelco's for me as far as LS engines go, or any aftermarket aluminum headed engine that requires the long reach plugs.
ACdelco does however still offer colder heat ranges for the old 1/2 inch reach plugs used in older engines, in which they work fine, and I still use them in those applications.

I am willing to bet the misfire wasn't the E3 plugs you put in now that I saw your other thread about the cam install.
Get your car tuned before putting in A GOOD plug in. Get AutoLite AR103's once it is tuned.

And never use a plug with more than one 'prong' or whatever they call it.

Bosch is terrible.
