Thread: SLP Header Installed

Hi Chris
yeah i sure will
do a scan for you...
I will put the scan on and do a long run with it
and post up the findings....

The plugs i just took out were installed in Sept 29th 2007
and were AC Delco 12568387 -- ITR 4A -- 15

I believe this is a stock plug for the GTP's..

The scan that is on here now was taken while sitting in the parking lot,
and was done as it just warmed up..
I will do a proper reading and post it up soon.

I will find out what plug the one guy is useing..
as he has alot of boost i believe around 10 or 12 PSI
But don't quote me on that as i am not sure..
and has a cam rockers et... he is in the 12 sec club so has
some work done.. --->He uses the same plugs GOR15LGS

we went for a long run tonight to Toronto which is about 135 miles
from here on the 401.
All i can say is wow awsome responce and power is right there.

As is it is hard to tell jumping from the AC Delco to these,
and would like to test the 104's and these to see the difference..

Thanks John

I would waste the time trying AL 104's they are just a plug and nothing special.
I never got a response to my second email about running their non resistor plugs. I remember these now. Last time I did the email thing with them I couldn't get consistant answers.

That is to bad..
I hate that when companys
will not answer questions or responces..
I'm going to give them a call also..

Thanks John

I think I'm going to call them. I like the idea of silver plugs because of their electrical and thermal properties. Of cousre copper has better properties than iridium and the iridiums seem to be a better plug for my car.
I'm going to call Brisk later today and find out why they recommended a non resistor plug for my car. Since I am a sparkplugaholic, I almost have to try something they offer in a silver.

You and I have something in common. I try just about all of them that come out. The most recent ones I tried were E3 plugs. I cant say they got a good test because one of the plugs failed on me. It shorted out which I dont think I have ever seen a plug do, but it shorted out internally.

Well is way to soon to be saying this,
But i have had the plugs in since Thursday
and i am still very much impressed....
Our gas milage around town has improved..
we were getting 21 to 22--- is is now holding at 25
for city driving.
Hwy driving was at 28 to 31 and now is 35.8
Traffic pendending...
The motor once it warms up is just awsome
and very smooth and can still feel the difference
in the power..

But like i said is still to early to be making judgement calls

That is a great initial review. I wished I could run that type of plug. We shall see what they tell me over the phone later today, as I only want to buy the right Brisk plug for my mod level. Heck I'm excited for you.

Update on my Brisk search. I spoke with someone at Brisk a few minutes ago. He confirmed that only a stock or mildly modded car should use the LGS series plugs. The reason behind this is that on a boosted or higher compression vehicle, with the plug gap on the LGS not being adjustable, it is too wide and the center electrode will arch to the resistor burning it out. Weird, I never considered my car as anything but mildly modded.

The gentleman I spoke to today also told me to run the G14YS. He said the silver racing plugs were the ones that tested to improve HP by 4 and not the LGS. However, he is looking into the recommended plugs not being a resistor plug. He or the initial person I emailed on Friday will call me back after noon today with more information. The madness continues.
